Question

The end product of carbohydrate metabolism is

• A. CO${}_2$ and H${}_{2}O$
• B. NH${}_3$ and CO${}_2$
• C. NH${}_3$ and H${}_{2}O$
• D. CO${}_2$

Answer 1

The correct option is A CO${}_2$ and H${}_{2}O$

• Starches or other complex carbohydrates are digested in the small intestine to glucose, which is absorbed into the blood.
• The absorbed glucose is transported all over the body to the cells. Glucose is metabolized to carbon dioxide, water, and ATP in the cells by three respiratory cycles glycolysis, Krebs cycle, and electron transport chain.
  

So, the correct answer is option A.
