Question

How does your body use the protein once it has been ingested? Consider the following statements and select the correct ones regarding protein use. Select all that apply. ► View Available Hint(s) Amino acids are used to create new proteins. If you ingest more protein than your body needs, the protein is stored in muscle. The liver uses amino acids to create glucose. If calorie intake is inadequate, amino acids can be used for production of energy

Answer 1

Ans.)

1. Amino acids are used to create new proteins.(TRUE)

When we take proteins, they are broken down by the body into amino acids.These amino acids are then reassembled into the type of protein that our body needs.

2.If you ingest more protein than your body needs,the protein is stored in muscle.(FALSE)

Our body cannot store proteins like carbohydrates and fats.So, excess proteins/amino acids are converted into glucose, can be used for energy production or excreted out.

3.The liver uses amino acids to create glucose.(TRUE)

Gluconeogenesis is the process by which amino acids(or other non carbohydrate sources) are utilized in the production of glucose.

4.If calorie intake is inadequate,amino acids can be used for energy production.(TRUE)

But this is not the ideal condition as our primary source of energy is carbohydrates followed by fats.

1.)Mouth

• Mechanical digestion begins here.

2.)Stomach

• HCl is secreted here.
• HCl denatures protein here.
• Pepsin is formed from pepsinogen here.

3.)Small intestine

• Single amino acids, dipeptides and tripeptides are absorbed here.

4.)Pancreas

• Enzymes that digest amino acid chains are produced here and delivered via duct to the small intestine.

5.)Liver

• Amino acids that enter the blood stream from the small intestine travel to here.
