Final answer:
Starch and glycogen are both polysaccharides composed of glucose units. However, they differ in their structure and function.
Step-by-step explanation:
Starch and glycogen are both polysaccharides composed of glucose units. However, they differ in their structure and function.
Starch is found in plants and serves as a storage form of energy. It consists of two polymers: amylose, which is linear, and amylopectin, which is branched.
Glycogen, on the other hand, is found in animals and functions as a storage form of energy. It is a highly branched polymer of glucose units, and it is more highly branched than amylopectin.
