Concept explainers

Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the p…

Lock And Key Model

The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique dist…

Textbook Question

Chapter 3, Problem 3.24P

When oxaloacetic acid and acetyl-coenzyme A (acetyl-CoA) labeled with radioactive carbon-14 in position 2 are incubated with citrate synthase, an enzyme of the tricarboxylic acid cycle, only the following enantiomer of [2-^l4C]citric acid is formed stereoselectively. Note that citric acid containing only ¹²C is achiral. Assign an R or S configuration to this enantiomer of [2-¹⁴C]citric acid. (Note: Carbon-14 has a higher priority than carbon-12.)
