(LE 2) Cell Respiration and Metabolism

Question 1

What is beta oxidation of fatty acids?

Answer 1

enzymes remove acetic acid from fatty acid to form acetyl CoA to be used in the Kreb’s cycle

Question 2

What is transamination?

Answer 2

Pyruvate and other Kreb’s cycle intermediates are converted into amino acids by adding an amine (NH3) group. Requires vitamin B6 as coenzyme

Question 3

What is oxidative deamination?

Answer 3

Removal of an amine group from an amino acid leaving pyruvate or another krebs cycle intermediate to make energy or converted to glucose or fat

Question 4

What is gluconeogenesis?

Answer 4

formation of glucose from amino acids and occurs in the Cori cycle

Question 5

What is glycogenolysis?

Answer 5

Hydrolysis of glycogen to yield glucose 6-phosphate for glycolysis or if in the liver free glucose

Question 6

What is gluconeogenesis?

Answer 6

glucose production from noncarbohydrate molecules like lactic acid or amino acid
