From the statements given below regarding enzymes, choose the correct option:
A. Enzymes that catalyze the inter-conversion of optical, geometric, or positional isomers are called Isomerases.
B. Dehydrogenases catalyze the transfer of electrons from one substrate to another.
C. Hydrolases catalyze the linking of two molecules using ATP.
D. Proteases and Lipases belong to the class of Hydrolases.
E. Transferases only transfer hydrogen atoms between substrates.
Choose the correct answer from the options given below:
A, B, C only
B, C, E only
A, B, D only
C, D, E only
A (True): Correct definition of Isomerases.
B (True): Dehydrogenases (part of Oxidoreductases) catalyze the transfer of electrons/protons.
C (False): The enzymes that link molecules together using energy (like ATP) are Ligases, not Hydrolases.
D (True): Digestive enzymes like Proteases and Lipases break bonds using water, making them Hydrolases.
E (False): Transferases transfer groups other than hydrogen. (Transferring hydrogen is the job of Oxidoreductases/Dehydrogenases).
