| True | |
| False |
Homework Answers
1. A competitive inhibitor binds to the active site of the enzyme and inhibits the substrate binding. In this, the carbon monoxide acts as a competitive inhibitor. A non competitive inhibitor binds to the site other than the active site of the enzyme.
The answer is A.
2. The scaffolding molecules,can ermanently hold groups of signaling proteins together in one place. These are key hubs of information downstream of activated GPCRs.
THe answer is true.
