epithelium. This type of epithelium with tall columnar cells is adapted for absorption
and is also protective. The epithelium of the proximal convoluted tubule has microvilli
that increase the surface area for reabsorption of water and minerals back into
the bloodstream. </span>

Answer: Option D) cofactor that is an activator of the enzyme.
Explanation:
A cofactor is a non-organic component (usually a metal) of an enzyme or protein, that enhances its function. Good examples of Cofactors include iron in hemoglobin, zinc in carboxypeptidase.
Zinc at the active site of the enzyme, carboxypeptidase helps it in cleaving off aromatic amino acids.
The three important agents which are involved in chemical weathering are –water,, carbon dioxide and oxygen. Among the three most important chemical weathering agent is water. With a simple formula H2O, the two hydrogen atoms bonded to one oxygen atom. This structure of water gives it a polar molecule property due to which it can polarize itself into negative and positive poles. The hydrogen is the positive pole with (+1) charge while the oxygen is the negative pole with (-2) charge and they attract ions opposite to their charge numbers.This exerts a molecular force on the surrounding molecules and they dissociate to get polarized and form new molecule. This process is called hydrolysis where a mineral is dissolved in water and ions from the minerals are carried away. These elements undergo the process of leaching.
