Biochemistry Test (AAM)

What is the main role of Amino Acids?

Synthesis of structural and functional proteins

How are essential amino acids gotten?

From diet

T/F: The body's amino acid pool is always in a dynamic steady state.

True

What is amino acid pool?

The amino acid pool is the total amount of free amino acids present in the body at a given time that is available for metabolism and protein synthesis.

What is meant by the statement "the amino acid pool is always in a dynamic steady state"?

Because amino acids are constantly added to and removed from the pool while its overall size remains relatively constant.

Discuss the digestion of proteins

What are the classification of proteolytic enzyme

Endopeptidases: Acts on peptide bonds inside the protein or peptide chain, producing smaller peptides.

Exopeptidases: Acts on peptide bonds at the end of the protein chain, releasing amino acids

How many carriers has amino acids? What are they?

5 carriers

Neutral, Basic, Acidic, imino, and beta amino acid

What is Nitrogen balance?

The measure of the difference between nitrogen intake and nitrogen excretion.

When is the body in positive nitrogen balance

1. Active growth and tissue repair after surgery

2. Pregnancy

When is the body in negative nitrogen balance?

1. Fever

2. Starvation

Anabolism vs catabolism

Anabolism is synthesis or build up. Catabolism is breakdown.

What are the five stages of nitrogen cycle?

1. Nitrogen Fixation

2. Nitrification

3. Assimilation

4. Ammonification

5. Denitrification

Nitrogen is most readily absorbable by plants in what form?

Nitrate(
