<h3><u>Question</u><u>:</u><u>-</u></h3>
The active site of an enzyme
a. Is where the semi-permeable membrane is located
b. Is a specific bulge of protuberance on an enzyme
C. Is a groove or crevice in the structure of the enzyme into which the substrate fits
d. Rigidly resists any alteration of its shape
<h3><u>Answer</u><u>:</u><u>-</u></h3>
C. Is a groove or crevice in the structure of the enzyme into which the substrate fits.
<h3><u>Explanation</u><u>:</u><u>-</u></h3>
The active site is one such gap or pocket to which the substrate adapts and binds to the enzyme.
The active site is the region of the enzyme to which the substrate molecule binds and causes a chemical reaction. The active site is composed of amino acid residues that form a temporary bond with the substrate.
Answer:
<u>protein and lipids</u>
Explanation:
Proteins, like carbohydrates and lipids, are compounds of carbon hydrogen and oxygen. However, unlike carbohydrates and lipids, proteins also contain the element nitrogen and are hence referred to as nitrogenous compounds. In addition to nitrogen, proteins may contain phosphorus or sulphur or both. Some proteins such as haemoglobin contain other elements such as iron.
The sodium concentration is higher outside the cell than
inside the cell and the potassium concentration is higher inside the cell than
outside the cell.
Because the sodium-potassium exchange pump moves sodium and
potassium ions in opposite directions, the pump generates concentration
gradients for these ions that are opposite in direction.

A nonsense mutation occurs. The presence of the stop codon results im the production of a shortened, and most likely nonfictional protein.
