The _____ model describes how the enzyme and substrate change shape upon binding.
Understand the Problem
The question is asking for the name of a specific model used in biochemistry that explains the interaction and conformational changes that occur between an enzyme and its substrate during binding. This is likely referencing a concept related to enzyme action mechanisms.
Answer
Induced fit model
The final answer is the 'induced fit' model.
Answer for screen readers
The final answer is the 'induced fit' model.
More Information
The induced fit model explains that upon substrate binding, both the enzyme and the substrate undergo a conformational change to achieve an ideal fit for catalysis, enhancing the interaction strength.
Tips
A common mistake is confusing the 'induced fit' model with the 'lock and key' model, which suggests a rigid and non-flexible enzyme active site.
