What is denaturation?
a) when an enzyme is given special powers to work better
b) when the rate of a reaction will happen faster
c) when an enzyme's active site gets deformed and loses is specific shape
d) when enzymes work at a faster rate
What does a competitive inhibitor do?
a) It competes with the substrate for the active site and slows down the reaction
b) It speeds up the rate of the reaction
c) It helps the reactants to react faster
d) It does not affect a reaction at all.
What is a catalyst?
a) increases the activation energy
b) like an enzyme and it lowers the activation energy
c) it is like an inhibitor and stops reactions
d) it does nothing
How does substrate concentration change the rate of a chemical reaction?
a) The higher the substrate, the slower the rate of reaction
b) The lower the substrate the faster the rate of reaction
c) The higher the substrate the faster the rate of reaction
d) There is no change
Increasing the temperature of the reaction will do what?
a) increase the rate of the reaction
b) stop the reaction
c) lower the rate of the reaction
d) cook all of the reactants
Where does your body get the energy for reattaching a third phosphate to ADP, creating ADP?
a) from the sun
b) usually from carbs
c) from nucleic acids
d) from breaking ATP
Which of the following reactions DIRECTLY provides chemical energy for most cell functions?
a) ADP = ATP + P
b) ADP + P = ATP
c) ATP + P = ADP
d) ATP = ADP + P
Which phrase BEST describes the function of the ATP molecule?
a) absorbs energy
b) increases energy
c) stores energy
d) creates energy
Energy is released from an ATP molecule for cellular processes when it
a) converts a phosphate group to ADP
b) attaches an extra phosphate group
c) loses a phospate group
d) produces a sugar molecule
Reactants bind to enzymes at the
a) substrate
b) product
c) activation energy

The molecule that an enzyme binds to is known as its
a) substrate
b) monomer
c) polymer
d) matching base
If the activation energy of a biochemical reaction is lowered, then
a) the reaction will happen faster
b) the reaction will happen more slowly
c) this will not affect the rate of the reaction
d) the reaction will not happen at all

a) catalyst (enzyme)
b) reactant
c) product
d) substrate

b) 6H20, C6H12O6, and 6CO2
c) 6CO2 and C6H12O6
d) C6H12O6 and 6O2
Chemical reactions that ABSORB more energy than they release are called
a) exothermic
b) catalyzed
c) endothermic
d) activated
What phrase best describes an exothermic reaction?
a) does not absorb energy
b) forms products with higher bond energy than reactants
