Please help answer questions 25-29

The synthesis of palmitic acid (16 C) requires ________ molecules of malonyl CoA A. 1 B. 7 C. 8 D. 16 After a 24-hour fast, which of the following sources of energy will be substantially decreased? A. glycogen B. triacylglycerides C. glucose D. amino acids E. Fatty acids The digestion of ingested lipids in the intestine requires: A. peptidases B. bile salts C. pancreatic lipase D. A and C E. B and C During each turn of the B oxidation of fatty acids, the products of appear in the following order: A. NADH, FADH_2 and acetyl CoA B. FADH_2, acetyl CoA and NADH C. acetyl CoA, NADH and FADH_2 D FADH_2, NADH and acetyl CoA E. None of the above reflects the sequence Acyl carrier protein (ACP): A. is a SH containing prosthetic group of the fatty acid synthetase complex B. transports long-chain fatty acids in the blood C. transports long-chain fatty acyl groups across the inner mitochondrial membrane D. is a cofactor of the dehydrogenases involved in beta oxidation E. none of the above With respect to lipoprotein metabolism: A. VLDL are converted to LDL mostly in the capillaries of adipose tissue B. lipoprotein lipase is activated by glucagon C. free fatty acids in plasma are carried by lipoproteins D. chylomicrons contain high concentration of protein

Explanation / Answer

25)b , i.e it requires 7 molecules of malonyl coA.

26)c, glucose, but after prolonged duration of fast amino acid level begins to decrease.

27)e, as their actions result in tiny droplets of fats and separate from the watery components.

28)c

29)c, because it is an important component in synthesis of fatty acid as it transport fatty acyl grp across inner motochondrial membrne.

30)A
