If the pinsulin receptor, a, example of an integral membrane protein, is cotranslationally inserted into the ER membrane with th
kicyunya [14]

Answer:

The correct answer is option C.

Explanation:

As the proteins are produced in the endoplasmic reticulum membrane, they amalgamate with the vesicles and then they are conducted towards the membrane's cell surface where they act as an integral membrane protein.  

The outer end will bind with the ligand and the other one will get attached towards the cytoplasm. Thus, the pinsulin in the given case will combine with the C terminus of the protein.

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
