Question

question 3/enzymes that catalyze the removal of electrons from one substrate and the addition of electrons to another are called
a lyases
b isomerases
c transferases
d oxidoreductases
e ligases

Explanation:

Oxidoreductases are enzymes that catalyze oxidation - reduction reactions. Oxidation involves the removal of electrons (or hydrogen atoms, which are equivalent to electrons + protons) from a substrate (the substance being oxidized), and reduction involves the addition of electrons (or hydrogen atoms) to another substrate (the substance being reduced).

• Lyases catalyze the addition or removal of groups without hydrolysis.
• Isomerases catalyze the rearrangement of atoms within a molecule.
• Transferases transfer functional groups from one molecule to another.
• Ligases catalyze the joining of two molecules with the use of energy (usually from ATP).

Answer:

D. oxidoreductases
