Explanation:
The best description of the function of the enzyme protein kinesis among the given options is:
- It activates protein phosphatase molecules.
Protein kinases are enzymes responsible for adding phosphate groups to proteins, a process known as phosphorylation. This phosphorylation can activate or deactivate proteins, depending on the specific protein and its role in cellular signaling pathways. So, protein kinesis would activate protein phosphatase molecules by adding phosphate groups to them, thereby modulating their activity within the cell.
