Lipid and Amino Acid Metabolism

Question 1

Transport Molecules for Lipids

Answer 1

chylomicrons, VLDL, LDL, IDL, HDL

Question 2

Key enzyme in cholesterol biosynthesis

Answer 2

HMG-CoA reductase

Question 3

Fatty Acid that we can synthesis

Answer 3

Palmitic acid

Question 4

Palmitic Acid synthesis

Answer 4

produced in the cytoplasm from acetyl CoA transported out of the mitochondria

Question 5

Fatty Acid Oxidation

Answer 5

Occurs in the mitochondria following transport by the carnitine shuttle, via beta oxidation

Question 6

Ketogenesis

Answer 6

ketone bodies form during a prolonged starvation state due to excess acetyl-CoA in the liver

Question 7

Ketolysis

Answer 7

regenerates acetyl-CoA for use as an energy source in peripheral tissues

Question 8

Protein Catabolism

Answer 8

digestion of proteins occurs primarily in the small intestine, carbon skeletons of amino acids are used for energy either via gluconeogenesis or ketone body formation, amino groups are fed into the urea cycle for excretion

Question 9

Fatty Acid Biosynthesis Occurs in

Answer 9

the liver
