22. A young animal has never had much energy. He is brought to a veterinarian for help and is sent to the
animal hospital for some tests. There they discover his mitochondria can use only fatty acids and amino
acids for respiration, and his cells produce more lactate than normal. Of the following, which is the best
explanation of his condition?
(A) His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial
membrane.
(B) His cells cannot move NADH from glycolysis into the mitochondria.
(C) His cells contain something that inhibits oxygen use in his mitochondria.
(D) His cells lack the enzyme in glycolysis that forms pyruvate.

(A) His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane. 正確
(B) His cells cannot move NADH from glycolysis into the mitochondria.
沒有太大的關聯
(C) His cells contain something that inhibits oxygen use in his mitochondria.
可用脂肪酸和氨基酸呼吸作用，代表後續電子傳遞練也OK，所以沒有抑制氧氣的問題
(D) His cells lack the enzyme in glycolysis that forms pyruvate.
製造乳酸代表有pyruvate
