Which one of the following statements about glycogen is correct? Glycogen is found in the muscle and liver cells of humans. Glycogen is the only storage form of glucose in humans. Glycogen is formed exclusively by gluconeogenesis. Glycogen is less branched than amylopectin. all the above a and b b, c, d c and d

a and b

Plants store glucose in which form(s)? Amylose Glycogen Amylopectin Maltose all the above a and c b and d a, c and d

Why can't the human body breakdown cellulose? The human body lacks the enzymes to digest cellulose. Cellulose contains fructose, which is difficult to use in metabolic pathways. Cellulose is insoluble in water so it cannot be broken down The bond configuration between glucose molecules is different in cellulose than it is in glycogen. all the above a, b and d b and c a and d c and d

a and d
