Which of the following statements regarding the similarity in glycogen in animal cell and starch in plant cell is/ are NOT correct ?

1. Both are mixtures of amylose and amylopectin
2. Starch and glycogen, both represent the storage form of carbohydrate in liver cells

Select the answer using the code given below :

Result
Your answer: —  ·  Correct: C

Explanation

Both statements are incorrect. Statement 1 is incorrect because starch is a mixture of two polysaccharides: amylose (linear) and amylopectin (branched). In contrast, glycogen is a single type of highly branched polymer of glucose, often referred to as "animal starch," but it does not contain amylose.

Statement 2 is incorrect because starch is the primary storage polysaccharide in plants, whereas glycogen is the storage form of glucose in animals, found primarily in the liver and muscle cells. Liver cells do not store starch; they store glycogen to maintain blood glucose levels. Since the question asks for statements that are NOT correct, the correct answer is C (Both 1 and 2).
