Answer to Question 1
2
Rationale: The body derives energy in the form of adenosine triphosphate (ATP) from the metabolism of carbohydrates, fate, protein, and alcohol contained in foods and beverages. Energy is needed in the human body to power our body and to produce heat to maintain body temperature. We obtain this energy from stored chemical energy in foods we eat. Lactic acid, calcium carbonate, and potassium biphosphate do not produce energy for the body.
Answer to Question 2
B
Very high fever may denature body proteins, because the extreme heat changes the shape of the protein. Drug overdoses, vitamin deficiencies, and high stress levels do not denature proteins.
