You have isolated a previously unstudied protein, identified its complete structure in detail, and determined that it catalyzes the breakdown of a large substrate. you notice it has two binding sites. one of these is large, apparently the bonding site for the large substrate; the other is small, possibly a binding site for a regulatory molecule. what do these findings tell you about the mechanism of this protein?

1 it is probably a cell membrane transport protein–like an ion channel.
2 it is probably a structural protein that is involved in cell-to-cell adhesion.
3 it is probably an enzyme that works through allosteric regulation.
4 it is probably an enzyme that works through competitive inhibition.
5 it is probably a structural protein found in cartilage or skeletal tissue.

The accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. the accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. chimpanzees and gibbons are the most closely related the chimpanzee's closest surviving relative is humans orangutans are the primates least closely related to chimpanzees old world monkeys and gibbons are the most closely related
