The enzyme-substrate complex is
A) best described by the lock and key model.
B) not influenced by pH.
C) a terminal point for both the enzyme and substrate (neither can be reused).
D) more likely to occur in a 20 degrees C environment than a 40 degrees C one.

Question

Quizplus · Accepted Answer

The enzyme-substrate complex is best described by the lock and key model, where the substrate fits into the active site of the enzyme like a key into a lock. The other choices are incorrect because pH can influence the activity of enzymes, both the enzyme and substrate can be reused after the enzyme-substrate complex is formed, and the optimal temperature for enzyme-substrate complex formation can vary depending on the specific enzyme and substrate.
