What is photosynthesis???​

Answers

By definition, photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.

With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter.

Photosynthesis takes place in 2 stages:

In the first stage the plants absorb water from the soil through the roots. Through their stems they transport it to their leaves. In these it meets the sunlight captured by chlorophyll, which breaks the water molecule, separating hydrogen (H) from oxygen (O₂). The other stage is capturing carbon dioxide. This provides the carbon and oxygen atoms that, together with hydrogen and stored energy, will form the glucose molecule, from which compounds are produced that are the basis of food for plants and other living beings.

Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.

Which of the following best predicts the effect of not having ATP available to supply energy to this
process?
A. H+ ions will stop moving through the protein.
B. H+ ions will move in the other direction through the protein.
C. H+ ions will continue to move through the protein in the original direction but at a slower rate.
D. H+ ions will begin to move through the phospholipid portion of the membrane in the original direction.

Answers

H+ ions will stop moving through the protein is the effect of not having ATP

available to supply energy to this process.

ATP is the form of energy used by cells and it ensures that cells perform their

daily activities optimally. ATP is needed in a lot of metabolic reactions and

transportation of materials within cells.

When there is a lack of ATP, it means there is no energy required to

transport or move substances within a cell. This means that the H+ ions will

stop moving through the protein and is the most appropriate choice.

DNA and RNA are ______ that serve as templates that form proteins

Answers

Answer:

In the first step, the information in DNA is

transferred to a messenger RNA (mRNA)

molecule by way of a process called

transcription.... The mRNA sequence is

thus used as a template to assemble-in

order-the chain of amino acids that form a

protein.

A type of RNA that is called as ribonucleic acid type called as transfer RNA that is used for the production of the amino acid at a time and the protein assembly takes place at the ribosomes.

What is the role of DNA and RNA for the sake of protein synthesis ?

       

DNA are responsible for the providing out the code for the cell's activities and the RNA are responsible for providing out the service to make them proteins.

Each group of 3 bases in the  mRNA constitutes a codon and each codon is specifying  a particular type  of  amino acid. The mRNA sequence therefore used as a template to make the  assembly in order of the chain of amino acids which form a protein.

It is found that in all biological cells , usually occurs in cytoplasm of cell though its production takes place in nucleus. Whereas DNA is  providing the code for cell's activities and RNA is responsible for converting that code into proteins which carry various cellular functions.

nucleus...controls all the activities of the cell and carrries the genes

mitochondria..site for respiration that yields energy for the cell

endoplasmic reticulum... protein synthesis and lipids metabolism

vacuoles.... handle waste products and are responsible for regulation of osmotic pressure of a cell also

Explanation:

is this helpful?

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

A euglena is a unicellular organism. Choose an everyday object, such as a car, to use as a model of this euglena. Explain how the parts of the object model how the euglena's cell parts help it stay alive.

Answers

Answer:

a car:

Flagellum  is a long thread-like structure that works as a navigator or a steering wheel in a car. The thin filament helps an euglena to move forward in any direction it desires.

Cell membrane is like the doors on a car. They regulate what goes in/out. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.

The Nucleus is like the front seat of your car because the driver is in control of what the car does, goes, and what happens inside of the car.

Vacuoles is like the Trunk of your car because you store food, water and other wastes into your trunk, like were all the things go in the vacuoles.

Mitochondrion is like the battery on a car. It gives the motor energy so it can run like the mitochondrion produces energy for the cell.

Eyespot is like a radio, because in some cars, radios pull power directly from the battery from the car battery, and this is why you will get the car radios on while the engine is off

Explanation:

The internal structures found in a typical photosynthetic Euglena are as follows:

Pellicle: A thin, flexible membrane that supports the plasma membrane and helps them to change shape

Plasma Membrane: The selectively permeable membrane that protects the inner content of the cell from the outside environment

Cytoplasm: A jelly-like substance distributed throughout the cell that contains all the cell organelles

Chloroplast: Contains the green pigment chlorophyll that helps them to produce food using sunlight by photosynthesis

Nucleus: A membrane-bound organelle that contains the genetic material, DNA. It also contains a distinct nucleolus that contains RNA and helps the cell to synthesize proteins

Mitochondria: The energy-producing organelle that forms ATP. All cellular activities such as movement and reproduction are performed using the mitochondrial energy source

Ribosomes: Consists of RNA and proteins, and are responsible for producing all cellular proteins

Golgi Apparatus: Manufactures, stores, and transports large molecules such as carbohydrates and proteins within the cell

Endoplasmic Reticulum: The extensive network of membranes that helps to package and transport proteins to different organelles. It is of two types: rough endoplasmic reticulum (RER) – containing ribosomes attached to it; and smooth endoplasmic reticulum (SER) – devoid of ribosomes

Lysosomes: Small membrane-bound organelles filled with hydrolytic enzymes that break down large molecules such as carbohydrates, fats, and proteins

Contractile Vacuole: It maintains the water and salt balance within the cell

Reservoir: The inward pocket present near the base of the flagella where contractile vacuole dispels excess water

Flagellum: A long whip-like structure attached externally to the cell body that helps in cell movement. An amoeba contains two flagella, a short one that does not protrude out of the cell, and a long one that helps in swimming

Eyespot: A region that is highly colored and contains red-colored carotenoid pigments that help in the detection of light. It is sometimes called a stigma

Photoreceptor: Also known as the paraflagellar body, it is the light-sensitive region located near the flagellum that helps to detect light. It also helps in their movement towards and away from light stimuli, a process known as phototaxis  

Paramylon: They are stored starch-like carbohydrate granules composed of glucose produced during photosynthesis. Paramylon enables the organism to survive in low-light conditions when photosynthesis is not possible by acting as the food reserve for the cell. When the paramylon is enclosed in a sheath of polysaccharide, it is called the paramylon sheath of pyrenoid.

The flagellum of euglena, can be compared to the wheels of a car, as they are responsible for the movement of both.

What is Euglena?

Euglena is a genus of single-celled flagellated algae that can occur either as free cells or in colony form.

What is flagellum?

Euglenophytes have the presence of flagella as their main characteristic. They have two flagella, one longer than the other. The smaller flagellum does not emerge from the cell. The larger one is mainly used for locomotion.

With this information we can conclude that euglena has flagella for locomotion just as cars have wheels for locomotion.

How do we know that the ocean is continually absorbing carbon from the atmosphere, helping with climate stability?
O Increased carbon in the oceans have made them more acidic.
O Ocean pH has increased significantly in the last decade.
O There are bubbles like carbonation on the ocean surface.
O Fish we catch and eat from the ocean are made of carbon.

Answers

The concentration of carbon is increased in the oceans have made them more acidic.

Increased carbon concentration in the oceans which have made the ocean water more acidic is the indication that more carbon is absorbed by the ocean. When carbon absorbed by the ocean, the carbon reacts with water which produced carbonic acid.

This carbonic acid decrease the pH of the ocean water that adversely affect the marine organisms especially coral reefs. When the pH of the ocean water increases, bleaching of coral reef occurs because the algae living on them die so we can conclude that the concentration of carbon is increased in the oceans have made them more acidic.
