Types of Inhibition: Focus on the Basics
Michaelis-Menten enzyme kinetics, and especially keeping track of the various kinds of reversible enzyme inhibition, is one of the most challenging areas of biochemistry for many MCAT students. It’s extremely easy to get lost in the details of memorizing terminology, types of graphs, x-intercepts, y-intercepts, and so forth – but superficially memorized information is very READ MORE

MCAT Biology Question — Carbon Reactions
In the Felkin model, a carbon which is originally achiral can undergo a reaction to generate a single enantiomer with 98% yield (with the remaining 2% generating the opposite enantiomer). This type of reaction is best described as: A) Chiral chromatography B) Racemization C) Asymmetric induction D) Unimolecular elimination READ MORE

MCAT Biology – Substrate Concentrations
Noncompetitive inhibition differs from uncompetitive inhibition in that a noncompetitive inhibitor binds to an allosteric site on the enzyme and prevents it from catalyzing a reaction, whereas uncompetitive inhibitors bind to the enzyme-substrate complex and prevent catalysis. Increasing the substrate concentration would have which of the following effects? A) Increasing impact of uncompetitive inhibitor and READ MORE

MCAT Biology – Genetics
Cystic fibrosis is an autosomal recessive disease that causes severe breathing difficulties and a number of other symptoms. If a male and female, both of whom are carriers for the disease, have one child, what is the probability that the child will also be a carrier? A) 0% B) 25% C) 50% D) 100% READ MORE
