Which statement BEST describes the relationship between MPF and the cell cycle? A. Cyclin binds with an enzyme to produce MPF Cyclin, and as its concentration rises, it promotes mitosis. B. Cyclin binds with a factor to produce MPF enzyme, and as the enzyme's concentration decreases, it promotes mitosis. C. The MPF Cyclin concentration remains constant, as the rise and fall of the MPF enzyme controls the cell cycle. D. The MPF Cyclin concentration increases and decreases in a cycle, but does not control the cell cycle.

Option A

Explanation:

Cyclin binds with an enzyme to produce MPF Cyclin, and as its concentration rises, it promotes mitosis.

Therefore, cyclin binds with a factor to produce MPF enzyme, and as the enzyme's concentration decreases, it promotes mitosis; the MPF Cyclin concentration remains constant, as the rise and fall of the MPF enzyme controls the cell cycle; the MPF Cyclin concentration increases and decreases in a cycle, but does not control the cell cycle are not best described the relationship between MPF and cell cycle.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
