Why does one molecule of epinephrine release millions of glucose molecules?
- A
Hormones bypass enzymes entirely
- Bcheck_circle
Multi-step phosphorylation cascades amplify the original signal
- C
Glucose is stored as a pre-made signal
- D
Each epinephrine molecule binds millions of receptors simultaneously
Explanation
At each stage of the cascade, one active enzyme can produce many active downstream enzymes—giving exponential amplification of the original hormone signal.
