Enzymes,vitamins,and hormones are classified into a single category of biological chemicals because they all.........

How do enzymes increase the rate of chemical transformation?

Assertion : Enzymes have active sites and substrates have reactive sites on their surface respectively.
Reason : Active and reactive sites push the enzyme and substrate molecules away from each other.

Regarding the catalytic cycle of an enzyme action,select the correct sequential steps:
$A$. Substrate-enzyme complex formation.
$B$. Free enzyme ready to bind with another substrate.
$C$. Release of products.
$D$. Chemical bonds of the substrate broken.
$E$. Substrate binding to active site.
Choose the correct answer from the options given below:

Enzymes are the polymers of

Water-soluble and colloidal catalysts made of proteins are:
