What is Cellular Respiration and what is the formula for it?

Answers

Answer:

Summary. Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).

Explanation:

i said it first

Cellular respiration is the process in which the cells convert sugars into energy. The formula for cellular respiration is: C6H12O6+6O2>6CO2+6H2O

Explanation:

Enzymes are an example of a class of organic compounds called proteins.

PROTEINS:

Proteins are one of the four major biological molecules in nature (others being carbohydrates, lipids and nucleic acids).

Proteins play vital roles in living organisms, which includes regulating biochemical reactions, repair of structures etc.

Enzymes are biological catalysts that helps to regulate the rate of a reaction. Enzymes are proteinous in nature i.e. they are made of proteins.

Therefore, enzymes are an example of a class of organic compounds called proteins.

Why is there Cholesterol in your cell membrane?

Answers

Answer:

Cholesterol functions to immobilise the outer surface of the membrane, reducing fluidity. It makes the membrane less permeable to very small water-soluble molecules that would otherwise freely cross. It functions to separate phospholipid tails and so prevent crystallisation of the membrane.

Explanation:

Cholesterol functions to immobilise the outer surface of the membrane, reducing fluidity. It makes the membrane less permeable to very small water-soluble molecules that would otherwise freely cross. It functions to separate phospholipid tails and so prevent crystallisation of the membrane.

It helps to restrict the passage of molecules. Since it is small, it can work to fit and block off water soluble molecules from diffusing into the membrane.

how many codons equal one amino acid

Answers

Explanation:

hope the answer was helpful

Three codons equal one amino acid

CODON:

A codon is a nucleotide sequence consisting of three bases. The genetic code is read in a group of three nucleotide bases at a time, which are called codons.

Each codon encodes an amino acid. For example, codon AUG encodes methionine amino acid.

Each codon is read during translation to form an amino acid sequence. This means that the number of codons in a mRNA (nucleic acid) sequence determines the number of amino acids in a sequence.

Therefore, three codons equal one amino acid.

In mice, there are three options for fur color: black,grey and white. What type of inheritance is shown by these mice?

A. Simple
B. Co-dominance
C. Incomplete dominance
D. Sex linked inheritance

Answers

Answer:

C. Incomplete dominance

Explanation:

Incomplete dominance is a type of non-mendelian inheritance in which one allele does not completely mask the phenotypic expression of the other allele in a gene, hence, the blending of both alleles give rise to an intermediate third phenotype.

According to this question, there are three options for fur color in mice namely: black, grey and white. This is so because the alleles for black and white coloration exhibits INCOMPLETE DOMINANCE, hence, they produce a third phenotype (grey) that is a blend of both parental phenotypes.

Answers

The two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.

What are proteins?

Proteins are a major group of biological macromolecules composed of a linear chain of aminoacids that are linked by means of peptide bonds.

Proteins are fundamental macromolecules present in all biological systems and they can be made by one or more polypeptides in order to form molecules that exhibit primary, secondary, tertiary, and quaternary structures.

These macromolecular structures can be evidenced by the tridimensional shapes that adopt different proteins, which can be globular or fibrous.

In conclusion, the two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.

Describe the two stage life cycle of plants: the gemetophyte stage and the sopophyte stage

Answers

Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle.

Answer:

Photosynthesis is the process used by plants, algae, and certain bacteria to convert the energy from sunlight (or other usable light sources) into chemical energy. Chemical energy is the energy these organisms use for different metabolic processes. During this process, they take in the carbon dioxide produced by all breathing organisms and release oxygen, which we breathe in once again, into the atmosphere.

Read the excerpt from Story of My Life by Helen Keller.When we arrived in Baltimore, Dr. Chisholm received us kindly: but he could do nothing. He said, however, that I could be educated, and advised my father to consult Dr. Alexander Graham Bell of Washington, who would be able to give him information about schools and teachers of deaf or blind children. Acting on the doctor's advice, we went immediately to Washington to see Dr. Bell, my father with a sad heart and many misgivings, I wholly unconscious of his anguish, finding pleasure in the excitement of moving from place to place.
