What is a difference between starch and glycogen?

Answer 1

Answer:

Glycogen is produced by animals while starch is produced by green plants

Explanation:

Following are the differences between starch and glycogen-

1. The structure of starch is larger as compared to that of glycogen. Glycogens has one molecule while starch has two molecules of glucose

2. Glycogen is produced by animals in their liver, muscles, brain, uterus etc. therefore it is also known as animal starch while starch is produced by green plants.  

3. Glycogen has only branched structure while starch has both branched and chain structure.  

Answer 2
