Specialized proteins which function as catalysts for organic reactions are:
aldehydes ketones enzymes amino acids

enzymes

Explanation:

Enzymes are the special protein molecules present in the cells of the living organism. Enzymes do not participate as reactants in a chemical reaction instead they speed up the chemical reaction. This is the catalytic property of the enzyme. A substrate binds to the active site of the enzyme and gets converted into product. They play important role in respiration, digesting food, muscle and nerve function.

On the basis of the above description, Specialized proteins which function as catalysts for organic reactions are: enzymes.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
