• Lipase

What is a common inorganic cofactor mentioned in the video?

• Calcium

• Iron

• Vitamin C

• Vitamin D

What is the role of a coenzyme in enzyme activity?

• To change the enzyme's shape

• To assist in substrate binding

• To inhibit enzyme function

• To provide energy for the reaction

What is the difference between competitive and noncompetitive inhibitors?

• Competitive inhibitors bind to the allosteric site

• Noncompetitive inhibitors increase enzyme activity

• Noncompetitive inhibitors bind to the active site

• Competitive inhibitors block the active site

What is feedback inhibition?

• A process where enzymes are permanently deactivated

• A process where enzymes are activated by their substrates

• A process where enzymes are produced in excess

• A process where the end product inhibits the first enzyme

How do ACE inhibitors help in managing high blood pressure?

• By increasing angiotensin II production

• By blocking angiotensin-converting enzymes

• By enhancing enzyme activity

• By reducing enzyme production
