Select false statements for an enzyme promoting a chemical reaction by
1 Only (i) and (iv)
2 Only (ii) and (iii)
3 Only (ii), (iii) and (iv)
4 Only (iii) and (iv)
Explanation:
(c) Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur. Enzymes bind temporarily to one or more of the reactants the substrate(s) of the reaction they catalyze by lowering the amount of activation energy needed and thus speed up the reaction.
