Exam 6: Protein

The DIAAS assesses the digestibility of the amino acids in the ____.

Which of the following is a nitrogen-containing,nonprotein compound that performs an important function in the body?

During protein digestion,peptides are broken into free amino acids mainly ____.

What two major systems are used for protein degradation in most cells?

Purine degradation results in the formation of xanthine and creation of _____ by xanthine oxidase.

A mutation in the genetic code (i.e.,DNA)could result in the wrong amino acid inserted into the synthesis of a given protein,thereby affecting the ability of the protein to function properly due to changes in its conformation.

What are the indicators of visceral protein status and why are some more sensitive to changes than others?

The product(s)of pepsin's action is/are ____.

Serotonin is made from which amino acid?

For a transport protein that spans a cell membrane,one would expect to find hydrophobic amino acids clustered together within the membrane.

It is estimated that the intestine uses 30-40% of some of the essential amino acids absorbed from the diet.

Which of the following amino acids is ketogenic?

Damage-associated molecular patterns (DAMPs)are released in response to which process?

The measure of how much nitrogen is retained in the body for maintenance and growth rather than absorbed is the ____.

If you were deficient in vitamins B₆ and B₁₂ and had high blood levels of homocysteine,what dietary substance could remove some of the homocysteine by donating a methyl group to form methionine?

Match the amino acid to its precursor(s). -arginine

During fasting conditions,the circulating levels of glutamine and alanine are elevated-why is this? Hint: this question is focused primarily on the muscle,but also includes other tissues.

Which level of organization determines the final form of a protein molecule consisting of several polypeptide chains?

Succinyl-CoA is generated by the oxidation of ____.

Explain why genetic defects that prevent the synthesis of functional transporters may be serious.Give an example of a disease where this occurs and describe the symptoms associated with it.
