How are enzymes and substrates related? a. the enzyme and substrate are identical. b. each enzyme binds to one specific substrate c. the enzyme and substrate are mirror images of each other d. the enzyme produces the substrate.

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.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
