The regulation of a biomolecule through the addition or removal of a molecular tag involves __________ reactions.
A) coenzyme-dependent redox
B) reversible covalent modification
C) metabolite transformation
D) isomerization

Question

Quizplus · Accepted Answer

Reversible covalent modification involves adding or removing a molecular tag, such as a phosphate group or methyl group, to regulate the activity of a biomolecule. This process is a form of post-translational modification that can occur quickly and efficiently in response to cellular signals. Coenzyme-dependent redox reactions involve the transfer of electrons between biomolecules, metabolite transformation involves the conversion of one metabolite to another, and isomerization involves the rearrangement of a molecule's atomic arrangement to form an isomer. These processes do not necessarily involve the addition or removal of a molecular tag, making them less applicable to the regulation of biomolecules through reversible covalent modification.
