What is the role of creatine kinase in the myofibril?

Answers

Answer 1

Answer:

Creatine kinase (CK) has several functions in cellular energy metabolism. It catalyzes the reversible transfer of high-energy phosphate from ATP to creatine, facilitating storage of energy in the form of phosphocreatine.

Answer 2

The evidence suggests that the myofibrils' creatine kinase is sufficient to maintain typical tension and relaxation, typical Ca sensitivity, and typical kinetic properties.

What is myofibril?

On the long axis of the myocytes, groups of myofibrils—long contractile fibers run parallel to one another (long single multinucleated cells that combine to form the muscle).

On the cell's long axis, the myocytes are situated next to one another in parallel.

Creatine, a molecule found in your muscle cells that aids in the production of energy by your muscles, needs a phosphate group added to it by CK.

Creatine becomes the high-energy molecule, phosphocreatine, which your body uses to produce energy, when CK attaches phosphates to it.

According to the research, the myofibrils' creatine kinase is enough to keep their regular kinetic features, like tension and relaxation and Ca sensitivity, in place.

Thus, this is the role of creatine kinase in the myofibril.

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis ____________ .

Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy ____________ and oxidation of fat for energy ____________ .

Overall, when carbohydrate intake is excessive, lipogenesis ____________


Increase or decrease

Answers

Answer:

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis  decreases.

The process of conversation of stored glycogen in the liver and muscles  to glucose is Glycogenesis. It takes place when the blood glucose drops,below certain levels and the body cells need glucose for biochemical activities.Therefore, when there are excess CHO consumption,more glucose would be in the blood,and thus no need for glycogenesis.(breakdown of glycogen)

Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy __Increases__________ and oxidation of fat for energy ___decreases_________ .

Definitely, this is a simple logic.As the storage for glycogen is limited,excess glucose  move into the blood, since they can not be converted to glycogen.The glucose is expended through cellular reduce the amount in the blood. Therefore, Gluconeogenesis, the production of glucose from non-CHO substances drops. Hence beta- oxidation drops.

Overall, when carbohydrate intake is excessive, lipogenesis increases.The process of converting excess CHO to fatty acids.Biochemically it is the process of converting the Carbon precursor of acetyl co -A to fatty acids.Therefore this increases to synthesized more fatty acids from CHO

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be present in urine. Why do you think this symptom is especially concerning for young people?

Answers

Answer:

S.A for Edmentum and Plato

Like and Rate

In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.

Two differences between hormones and the nervous system

Answers

Answer:

Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.

Explanation:

Answer:

the nervous system and endocrine system (hormones) is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.

Which of the following is not a reason that nonnative species are reared outside their native ecosystems?
a. They are commercially important.
b. They are used to replace native species.
C. They are used for restocking programs.
d. None of the above

Answers

Answer:

D

Explanation:

All of the given reasons are reasons that nonnative species are reared outside their native ecosystems. The correct option is D.

What are nonnative species?

Non-native species are animals, plants, and other organisms that do not develop natively in a region but are instead introduced through intentional or unintentional human activity.

Non-native species, unlike invasive species, do not necessarily threaten or threaten the existence of other species within the ecosystem.

Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.

Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.

They are employed in restocking efforts, to replace native species, and for commercial purposes.

Thus, the correct option is D.

"Oh, well," replied the Hare, who was much amused at the idea, "let's try and see"; and it was soon agreed that the fox should set a course for them, and be the judge.

Meanwhile the Tortoise kept plodding on, and in time reached the goal. At last the Hare woke up with a start, and dashed on at his fastest, but only to find that the Tortoise had already won the race.
