← ScienceWhich consequence results when backpressure decreases the rate controlling step enzymes?
A)Increased substrate availability enzyme
B)Product inhibition within pathway reverses
C)Intermediate metabolite build-up toxicity✓
D)Substrates consumption faster enzyme rate
💡 Explanation
Intermediate metabolite concentrations lead because a slower enzymatic rate-controlling step inhibits the effective product removal via feedback inhibition; therefore toxic build-up, rather than rapid flux or removed product inhibition, results because those alternate hypotheses involve different mechanisms.
