Prepare for NEET Biology Biomolecules (Enzymes) with MCQs & PYQs on NEET.GUIDE. Access free practice, previous year questions, and expert guidance to examine enzyme kinetics, specificity, and regulation.
Oxygenic compounds of biological process, which activate chemical reactions are
Vitamins
Hormones
Enzymes
Fats
Choose the correct options
E + S → ES → E + P →EP
E + S ⇌ ES → E - P → E + P
E + S → ES ⇌ E - P → E + P
E + S ⇌ ES ⇌ E - P ⇌E+P
