Protein structure and enzyme function

Protein structure and enzyme function is part of Biochemistry in the MCAT Biological and Biochemical Foundations section. The questions below are written in the style of the real test, each with the answer and a worked explanation.

Question types you will see here include michaelis-Menten and reciprocal plots, inhibition type identification, allosteric and covalent regulation and residue substitution and structure.

Common traps: reading the x-intercept as -Km instead of -1/Km; mixing Vmax with the rate at a single substrate concentration; equating low Km with low affinity.
