MCAT Biological and Biochemical Foundations of Living Systems Flashcards: 1a Enzyme Structure Catalysis

Study 1a Enzyme Structure Catalysis in MCAT Biological and Biochemical Foundations of Living Systems with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

What does a low KmK_m indicate about an enzyme for its substrate?

Tap card or press Space to flip

ANSWER

High apparent affinity (less substrate needed to reach Vmax2\frac{V_{max}}{2}). Lower KmK_m means stronger binding, requiring less substrate for significant activity.

Practice questions

1 of 46Practice questions for this set
An enzyme-catalyzed reaction shows a burst phase: rapid product formation in the first few seconds followed by a slower steady-state rate, despite constant substrate excess. A single-turnover experiment suggests chemistry is fast but a later step is slow. Which mechanism best explains the burst kinetics?
