What is the relationship between CdKs and cyclins?

Cyclins activate CdKs during the cell cycle.

Cyclins are deactivated by CdKs during the cell cycle.

Cyclins and CdKs act independently of one another.

Cyclins create CdKs that are used during the cell cycle.

Answer:

The relationship between cyclins and CdK is that cyclins activate CdKs during the cell cycle.

Explanation:

CdK is the term used for cyclin-dependent kinases, molecules responsible for the phosphorylation of specific proteins within the cell cycle.

Both kinases and cyclins are cell cycle regulators, intervening in various steps of the human cycle. Kinases must be activated by cyclins in order to be able to couple to their substrate, being directed in this process by the same cyclins.

The other options are not correct because:

  • Cyclines do not deactivate CdKs.
  • CdKs and cyclines do not act independently in the cell cycle.
  • Cyclines activate CdKs, they do not create them.

Answer: A!! Cyclins activate CdKs during the cell cycle.

Explanation: just took the test!
