What type of enzyme can activate another enzyme by adding a phosphate from ATP?

Here my answer goes

Explanation:

In biochemistry, a kinase is an enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates. This process is known as phosphorylation, where the substrate gains a phosphate group and the high-energy ATP molecule donates a phosphate group.

b - the respond is innate and varies over time.

good luck!
