4. If carbohydrate or total energy intake is too low, the body has the ability to use amino acids(from dietary or body proteins) to provide energy?

True

False

5. The brain and nervous system have a constant need for:

Fat

Glucose

Protein

6. As proteins enter the stomach for digestion, what acid uncoils or denatures the protein so that digestive enzymes can begin dismantling the peptide bonds?

Sodium Chloride (NaCl)

Citric Acid

Sodium Hydroxide (NaH2)

Hydrochloric acid (HCl)

7. Proteins cannot be used for potential energy by being stored as fat.

True

False

Once in the bloodstream, the amino acids have several fates: they can be used for protein synthesis, immediate energy, or potential energy (fat storage).

Explanation

Once in the bloodstream, the amino acids have several fates: they can be used for protein synthesis, immediate energy, or potential energy (fat storage).
