Concept explainers
Interpretation:
The correct or incorrect statement is to be deduced from the given statements, and reason for each of them is to be explained.
Concept introduction:
A coenzyme is a varied group of small nonprotein, organic, freely diffusing compounds that are loosely attached with an essential that allows enzymatic activity, acting as the carrier molecules that transfer electrons, chemical groups, etc. The well-recognized coenzymes comprise adenosine triphosphate (ATP), which transfer the phosphate groups; nicotinamide adenine dinucleotide (both NADH and NADPH), which transfers hydrogen and electrons; coenzyme A, which transfers the acetyl groups; and the S-adenosylmethionine coenzyme, which transfers the methyl groups.

Why is the decrease of activity frequently much less when the solution contains high concentrations of the substrate?arrow_forward
