What is the role of cyclin-dependent kinases in the cell cycle?

Biology
1 answer:
jasenka [17]3 years ago
3 0

Answer:

They initiate various stages of the cell cycle.

Explanation:

Cyclins and cyclin-dependent protein kinases function to control  the cell cycle. A group of cyclins: the G1 cyclins, are synthesized during G1 phase and function  to activate CDPKs which initiate DNA synthesis at the G1/S checkpoint. The cell fails to  progress to S phase if there is no sufficient synthesis of G1 cyclins. After a cell passes through  this point, the G1 cyclins are degraded, allowing for another group of cyclins: the M cyclins  to be synthesized. M cyclins activate a second group of CDPKs which allow  the cell to pass the G2/M control point and into mitosis.

Natali [406]
The correct sequence is; Glycolysis-pyruvate-acetyl CoA-krebs cycle-electron transport chain. 
Glycolysis is a sequence of reactions for the breakdown of glucose to two molecules of pyruvic acid under aerobic conditions, Krebs cycle is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the energy carriers, while electron transport chain involves a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions and couples this transfer with the transfer of protons across a membrane.
