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:
Both 1 and 2
Both statements are incorrect. Being a mixture of amylose and amylopectin is a defining feature of starch, not glycogen, which is a distinct, more highly branched polysaccharide. Also, starch is stored in plant cells, not in liver cells, so describing both as a storage carbohydrate 'in liver cells' is wrong. Hence, statements 1 and 2 are both NOT correct.

In eukaryotic cells, covalently attached lipids help to anchor some water soluble proteins to the plasma membrane. One group of cytosolic proteins are anchored to the cytosolic face of membrane by a fatty acyl group (e.g. myristate or palmitate). These groups are generally covalently attached to which amino acids present at the N‐terminus of the polypeptide chain?
