List the 2 types of enzyme inhibitors and how each one works.
-Competitive inhibitor: binds to the active site of an enzyme
-Non-competitive inhibitor: binds to another part of an enzyme
What is a spontaneous reaction?
A spontaneous reaction happens without energy input, and increases the entropy of the universe
________ energy is associated with motion and heat, while _________ energy is associated with location and chemical energy.
-Kinetic energy is associated with motion and heat
-Potential energy is associated with location and chemical energy
Differentiate between catabolic and anabolic reactions.
-Catabolic: release energy, break down, spontaneous, ∆G:neg, exergonic
-Anabolic: consume energy, build up, non-spontaneous, ∆G:pos, endergonic
What is a nonprotein enzyme helper called? Hint: they are usually small metallic ions.
Cofactors are nonprotein enzyme helpers
What is activation energy?
Activation energy is the initial energy needed to start a chemical reaction
What binds to the active site?
A substrate binds to the active site of an enzyme forming an enzyme-substrate complex
What is the second law of thermodynamics?
Every energy transfer increases the entropy of the universe
What are the two factors that can influence optimal enzyme activity?
-Environmental factors (temperature, pH)
-Chemicals that specifically influence the enzyme
