問BIO 2005 CE MC Q.11 , Q.13 可唔可以解釋下個答案問黎?

最佳解答:

11. The answer is D. Excess amino acid will be converted to urea and carbohydrate in the liver. Amino acid will be deaminated then further converted to urea. (Amino acid → urea, it is NOT deamination.). Also, the amino base will be converted to carbohydrates and store in the body. For A, bile consists of old red blood cells, bile salt, but not amino acid and its by-products. For B, it is protein to make new cells. For C, it is explained above. 13. The answer is C. For A, bile is produced by the liver, not gall bladder. It is the gall bladder stores the bile. For B, bile consists of bile salt, which can turn fat into smaller oil droplets to increase surface area of lipase to digest fat. But bile does not contain an enzyme to digest fat. For C, it is stated above. For D, this is not a fact.
