Acell forms glycogen from simple sugars when food is plentiful. which statement describes this process?
a it is a catabolic reaction that is endothermic.
b it is an anabolic reaction that is endothermic.
c it is a catabolic reaction that is exothermic.
d it is an anabolic reaction that is exothermic.

The correct answer is-

B It is an anabolic reaction that is endothermic.

A cell forms glycogen from simple sugars when food is plentiful. In human beings, carbohydrates ( glucose) are stored in the form of glycogen in muscles and adipose tissue.

The formation of glycogen from glucose is called as glycogenesis and it requires large amount of energy ( endothermic reaction) as a larger molecule is formed from simple glucose molecules, which shows an anabolic reaction.

Thus, option B) is the right answer.

a bird that nests only in a particular tree species.
