If the product of a pathway down-regulates its own synthesis, this phenomenon would be called:
Correct answer: A. Feedback inhibition
- A. Feedback inhibition
- B. Feedback regulation
- C. Positive Feedback
- D. Enzyme activation
Explanation
Feedback inhibition is a specific type of regulation where the end product of a metabolic pathway acts to decrease its own production. This is done by inhibiting the activity of enzymes involved in its synthesis, helping to prevent excess accumulation of the product.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
