Answer:
Answer is D - cAMP.
Explanation:
cAMP is a small molecule that functions as an intracellular signaling molecule - a second messenger. The first messenger would be the thing that activated the GPCR (e.g. a hormone). The GPCR is a signal transducer (converts extracellular signal to intracellular signal). Once activated, the GPCR activates adenylate cyclase which can be called a signal effector - it is an enzyme that produces cAMP.

The answer is C, gravitational potential to kinetic, but just a side note beware of posting questions that are that kind of evaluation. People can track you down for using any sort of site for help. So just keep in mind just send in the picture but not type in the entire question so that way you don’t get detected or have to retake the entire thing. Good luck btw
