Question

question 9 (10 points)listenthe specificity of an enzyme to a substrate is currently best explained bythe allosteric model.the \lock and key\ model.the induced-fit model.the receptor model.

Explanation:

The lock-and-key model was an early idea but does not account for enzyme shape changes. The allosteric model describes regulation, not substrate specificity. The receptor model is not related to enzyme-substrate interactions. The induced-fit model, which states enzymes slightly change shape to fit their substrate perfectly, is the current best explanation for enzyme-substrate specificity.

Answer:

the induced-fit model.
