Answer:
On the explanation.
Step-by-step explanation:
Hello,
a. At first there exist an active site on the enzyme with a specific tertiary constitution, which is done by means of the hydrogen bonding gathering the amino acids in the primary structure. Such 3D structure brings to bear that only one substrate with complementary shape can dovetail to the aforesaid active site forming an enzyme substrate complex.
b. However, pH is a measure of hydrogen concentration present in the solution. Now, by considering that into the structure of the enzyme and its active sites are held by hydrogen bonds, varied concentrations of hydrogen ion can cause a decrease or increase of the ions, this could turn out in the diminishing of bonds numbers or the breaking of bonds, which could affect the shape of the enzyme's active site.
c. Next, the temperature has a directly proportional relationship with the enzyme molecule kinetic energy. Thus, high-order vibrations at high temperatures could promote the breaking of and cause the active site of the enzyme to be denatured. On the contrary, low temperatures causes both the enzyme and substrate to have low kinetic energy so the reaction could not be attained.
d. The active sites have a slight capacity to shape around multiple substrates, not just one, it means that similar substrates could bind with the active site and occupy the enzyme, consequently, there are less enzymes to react with, causing a halting in the chemical reaction.
Best regards.
