Which of the Following is a Common Energy Storage Polymer

Question

Which of the following is a common energy storage polymer in microorganisms?
A) acetyl~S-CoA
B) glycogen
C) adenosine triphosphate
D) H₂

Accepted Answer

Glycogen is a common energy storage polymer in microorganisms. It is a branched polysaccharide composed of glucose residues that can be quickly hydrolyzed to provide energy. Acetyl~S-CoA, adenosine triphosphate, and H₂ are all involved in energy metabolism but are not energy storage polymers in microorganisms.
