Exam 6: Protein

Lysosomes are found in all mammalian cells.

Urea synthesis only occurs in the liver and kidneys.

The liver is the site for transamination of all amino acids.

Transamination and Deamination: What are these two reactions in amino acid metabolism (draw a diagram if that is helpful)? Why are they important? (Hint-transamination is important for two reasons; deamination,essentially one.)How do different tissues factor into these reactions?

Legumes are limited in sulfur-containing amino acids,methionine and cysteine.What food group is considered complementary because it supplies these amino acids?

A particular amino acid is very important for several metabolic pathways in enterocytes and so it is often added to nutritional mixtures used for hospitalized patients.The important amino acid is ____.

Total body water increases steadily from birth to 12 months of age,after which it begins to decrease at a similar rate in all adults.

Bile is needed to produce taurocholate and glycocholate.

An intracellular deficiency of protease will interfere with ____.

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

What is the current Tolerable Upper Intake Level established for protein and amino acids?

Which process is NOT a source of ammonia ions in the body?

Which amino acid is used to synthesize glutathione?

A variety of transporters exist on cell membranes to handle all of the different types of amino acids.

Dietary proteins must be completely hydrolyzed to free amino acids,because only free amino acids are absorbed by the enterocyte.

Incomplete proteins are derived from foods of animal origin such as eggs,milk,cheese,meat,and fish.

One of the body's responses to metabolic stress is ____.

Choose the correct order of enzyme activities in protein digestion.

A genetic defect diminishing branched-chain alpha-keto acid dehydrogenase (BCKAD)complex activity results in ____.

When the amino group has been removed from an amino acid,the carbon skeleton or α-keto acid may be used in many different ways.Which of the following is NOT a possible fate for the carbon skeleton?
