Briefly describe how the cell cycle is controlled and why phosphorylation of proteins plays a major role.
Phosphorylation
Phosphorylation is a biochemical process that involves the addition of a phosphate group to a molecule, crucial for energy transfer and signal transduction in cells.
Cell Cycle
The series of events that take place in a cell leading to its division and duplication.

Final Answer :
Concepts to Consider: The cell cycle is controlled through cell cycle checkpoints which ensure that certain criteria are met before the cell proceeds to the next cycle phase. Proteins that catalyze cell cycle events are either activated or inactivated by phosphorylation. Cyclin-dependent kinases (Cdks) control the phosphorylation of other proteins, allowing them to regulate the transitions between phases of the cell cycle.
