Among the following options, what is the primary storage form of carbohydrates in mammals, and where is it predominantly stored?
Lactic acid in Cardiac muscles
Glycogen in Liver and Skeletal muscles
Glucose in Liver and Adipose tissue
Glycogen in Liver and Spleen
Option 2, Glycogen in the liver and skeletal muscles, is the correct answer. In mammals, glycogen serves as the primary storage form of carbohydrates. It is predominantly stored in the liver and skeletal muscles. Glycogen acts as a glucose reserve that can be broken down when energy demands increase. Hence, the correct answer is option 2.
