2. A molecule that binds to a receptor to trigger a cellular response.
3. A mechanism in which the output of a process influences its own activity, helping to regulate cellular signaling.
5. Main character of this story
7. The process by which a cell converts an external signal into a functional response, often involving a series of molecular interactions.
9. The addition of a phosphate group to a protein, typically by a kinase, which can activate or deactivate the protein.
10. An enzyme that catalyzes the addition of phosphate groups to proteins, thus activating or deactivating them.
