Question

How are enzymes and substrates related?

Answer 1

The correct choice is B. The enzyme binds to the substrate. The other choices are incorrect.

Answer 2

Answer:

The correct answer is option B.

Explanation:

Enzymes bind with specific chemical reactants called substrates in specific reactions.  Enzymes are very specific to substrates or reactants as they have a unique active site that only permits particular substrates to bind to the active site.

Each enzyme has a unique region on the enzyme surface known as the active site. This is a cleft or groove in the protein surface where the specific substrate binds. It has a unique shape that fits the reactant or substrate like a lock and key fits with each other and their specificity also similar to lock and key.

Thus, the correct answer is option B.
