What is the role of enzymes as biological catalysts?
What is the role of enzymes as biological catalysts?
- They permit reactions to occur only at extreme conditions and process few molecules every second
- They permit reactions to occur at body conditions and process few molecules every second
- They permit reactions to occur at body conditions and process millions of molecules every second (correct)
- They inhibit reactions to occur at body conditions and process millions of molecules every second
What is the effect of enzymes on activation energy (Ea) in a reaction?
What is the effect of enzymes on activation energy (Ea) in a reaction?
- Enzymes increase the activation energy, making the reaction slower
- Enzymes stabilize the activation energy, keeping the reaction constant
- Enzymes have no effect on activation energy
- Enzymes reduce the activation energy, making the reaction faster (correct)
What are the two basic components of an enzyme's active site?
What are the two basic components of an enzyme's active site?
- Allosteric site and regulatory site
- Substrate site and product site
- Catalytic site and binding site (correct)
- Inhibitory site and stabilizing site
