An animal that is endothermic and homoeothermic A. uses metabolic energy to regulate its body temperature and maintains a relati
rusak2 [61]

Answer: The correct option is A (uses metabolic energy to regulate its body temperature and maintains a relatively constant body temperature).

Explanation:

HOMOEOTHERMIC animals are also called endothermic animals. They are the warm blooded animals which uses heat energy generated metabolically to regulate and maintain a relatively constant body temperature. Examples of animals that are endothermic include the birds and mammals.

The temperature which they maintain is deep inside the body and not the skin temperature.

Also the temperature of a body is affected by the heat it gains and losses. The body gains heat mainly:

--> by absorbing it from its surroundings

--> from the heat released during the catabolic reaction that occur all the time in the body cells.

--> by conduction, convection and radiation from the surface of the body

--> through evaporation, especially of sweat and

--> in the air that is exhaled and urine that leaves the body.

Under normal circumstances, the heat the body gains is balanced by the heat it loses. A RISE in body temperature stimulates the following processes to get rid of excess body heat:

--> A decrease in metabolic rate: the body slows down its activities to decrease the metabolic rate. This reduces the heat released by metabolic reactions, hence minimizing heat production within the body.

A FALL in body temperature stimulates the following processes to produce and conserve heat:

--> increasing metabolic rate: The body increases its metabolic rate, especially that of the liver, to produce more heat

The benefit of measuring the initial rate of a reaction, V0, is that early in the course of the reaction, A) Km is the substrate
aleksandr82 [10.1K]

Answer:

Rate of product formation is linear and [S] has not been lowered significantly.

Explanation:

The rate of enzyme-catalyzed reactions is affected by several factors, the contraction of substrates [S] is one of them. The substrate concentration keeps on changing as the reaction proceeds. This is why the reaction rate is measured at the initial stages of reactions when the substrate concentration [S] is much greater than the concentration of the enzyme. It is called the initial rate or initial velocity.

Under the conditions of higher substrate concentration and relatively much lower enzyme concentrations, only a few molecules of substrates are being converted into product. At a relatively higher substrate concentration, the rate of product formation increases linearly.

Darya [45]

Not sure if I'm correct but my best guess is the cell membrane seeing as it surrounds the cell itself and is responsible for allowing certain molecules to diffuse in or out of the cell. Good Luck! :)
