Multiple Choice

Which of the following statements about glycogen is correct?

Glycogen synthesis occurs mainly in the mitochondria.

Glycogen is the main storage form of fatty acids in animal cells.

Glycogen is composed of repeating units of fructose linked by $eta$-1,4-glycosidic bonds.

Glycogen is a highly branched polymer of glucose found primarily in liver and muscle cells.

Verified step by step guidance

Step 1: Begin by understanding the structure and function of glycogen. Glycogen is a polysaccharide composed of glucose units linked together by glycosidic bonds. It serves as the primary storage form of glucose in animal cells.

Step 2: Analyze the incorrect statements one by one. The first statement, 'Glycogen synthesis occurs mainly in the mitochondria,' is incorrect because glycogen synthesis occurs in the cytoplasm, not the mitochondria.

Step 3: Evaluate the second statement, 'Glycogen is the main storage form of fatty acids in animal cells.' This is incorrect because glycogen stores glucose, not fatty acids. Fatty acids are stored as triglycerides in adipose tissue.

Step 4: Examine the third statement, 'Glycogen is composed of repeating units of fructose linked by β-1,4-glycosidic bonds.' This is incorrect because glycogen is composed of glucose units, not fructose, and the glycosidic bonds are primarily α-1,4 and α-1,6 linkages.

Step 5: Confirm the correct statement, 'Glycogen is a highly branched polymer of glucose found primarily in liver and muscle cells.' This is accurate because glycogen is stored in these tissues to provide energy during fasting or physical activity.
