Question

Quizplus · Accepted Answer

- Statement 1 is false because intermediates in glycolysis are phosphorylated derivatives of glucose, not glycerol or acetone.- Statement 2 is true; carbohydrate digestion begins with salivary amylase in the mouth, continues with limited action in the stomach due to the enzyme's denaturation by stomach acid, and is completed in the small intestine with the help of pancreatic amylase.- Statement 3 is true; glycogen is indeed the storage form of glucose in the body, synthesized through the process of glycogenesis.
