What is a common role of a coenzyme in a reaction as stated in class Group of answer choices To lower the activation energy of a reaction further The donation of atoms to a reaction To alter the enzymes shape To assist the substrate by binding to the enzyme, enabling substrate to active site engagement

To assist the substrate by binding to the enzyme, enabling substrate to active site engagement

Explanation:

A coenzyme is a molecule that functions to aid the enzyme in catalyzing a reaction. The coenzyme does this by binding to the active site of the enzyme, then allowing substrate to bind to the enzyme for reaction to occur.

In other words, the coenzyme assists the substrate by binding to the enzyme, enabling substrate to active site engagement.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
