[单选题]
Which of the following (sy0o99ygo ,kvez /hhmacromolecuzt p:ej)*gafki u3u60les describe a typical enzyme?
A. Macromolecule is Protein, Type is Fibrous
B. Macromolecule is Lipid, Type is Hydrophobic
C. Macromolecule is Protein, Type is Globular
D. Macromolecule is Lipid, Type is Hydrophobic
参考答案: C
本题详细解析:
Almost all enzymes are globular proteins and differ freda6m0+tp aybg 1q(+/ ko(zno om fibrous proteins in that they are sensitive to pH and temperature and are mostly water soluble.
Fibrous proteins (Choice A), unlike globula/gakbo61en+yd+aot ( (qzp0m r proteins, are long and narrow, less sensitive to changes in pH and temperature and are generally insoluble in water. Enzymes are not lipids (Choices B, D). Enzymes tend to be hydrophilic, not hydrophobic since they are mostly soluble in water.
