Epinephrine is a hormone that regulates cellular energy metabolism to break down glycogen into glucose. The signal transduction pathway involves the production of cAMP. If caffeine blocks the activity of cAMP, what would happen to the signal transduction pathway? The signaling pathway will amplify and produce more glucose.
The signaling pathway will conform to bind to the receptor cells.
The downstream components will be altered and ultimately affect production of glucose.
The downstream components will function normally.
