The action of protein kinases in the cell is often described as a form of___________

Answer 1

Protein kinases in the cell are a form of cellular signaling.

Step-by-step explanation:

Protein kinases, which are enzymes that catalyze the transfer of a phosphate group onto proteins, are often described as a form of cellular signaling. They play a crucial role in regulating various cellular activities by activating or deactivating target protein molecules through phosphorylation. This process involves the addition of a phosphate group to the target protein, leading to changes in its structure and function.
