Answer 1

1) glycogen is formed from glucose it is a polymer of glucose, breaking down of glycogen to glucose is not a synthesis reaction so the answer is b. glycogen forming glucose molecules

2) protein is formed by joining amino acids so the answer is amino acid.

3) starch is the polymer of glucose similarly protein is the polymer of amino acid so the answer is  a protein is to an amino acid.

4) glycogen is formed from glucose it is a polymer of glucose, breaking down of glycogen to glucose is not a synthesis reaction so the answer is b. glycogen forming glucose molecules
