MCB Exam #1 Questions with correct answers
Substrate Competitive Inhibitor - ✔✔Km increases
Vmax unaffected
acts at the active site
Non- Competitive Inhibitors - ✔✔Km is unaffected
Vmax decreases
Substrate Dependent Inhibitors - ✔✔Km decreases
Vmax decreases
Ways Enzymes catalyze reactions - ✔✔1. Lowering activation energy
