[問題] 求救生物化學兩題
剛剛做生物化學的考古題遇到兩題不會的..
1.Non-steroidal anti-inflammatory drugs(NSAIDS) like aspirin and ibuprofen act
by blocking production of:
A) biological waxes.
B) prostaglandins.
C) sphingolipids.
D) vitamin D.
2.Fatty acids are activated to acyl-CoAs and the acyl group is further
transferred to carnitine because:
A) acyl-carnitines readily cross the mitochondrial inner membrane,but
acyl-CoAs do not.
B) acyl-CoAs easily cross the mitochondrial membrane,but the fatty acids
themselves will not.
C) carnitine is required to oxidize NAD+ to NADH
D) fatty acids cannot be oxidized by FAD unless they are in the acyl-carnitine
form.
麻煩高手幫我解答這兩題，感謝。
