What is metabolism?
Describe catabolism and anabolism.
Describe anabolic pathways.
Energonic vs. exergonic
Oxidation vs. reduction
What is free energy?
o What happens to free energy for systems in equilibrium,
o What type of reactions have a positive G.
o What type of reactions have a negative G.
Why is ATP such an important molecule in metabolism? How does ATP provide energy?
What is a catalyst?
What is an enzyme
Describe how catalysts/enzymes work.
What is activation energy?
Know the following:
o Active site
o Substrate
o Product
What is the induced fit hypothesis?
What is a coenzyme?
What is a cofactor?
Know the different types of inhibition:
o Allosteric
o feedback
o Reversible inhibition etc..
What is a non-competitive inhibitor vs. a competitive inhibitor
Explain how disappearance of enzyme, substrate, product etc.. affect rate of enzyme
catalyzed reactions.
Be able to interpret a graph that shows the differences between an enzyme catalyzed
reaction and the reaction without an enzyme:
o Activation energy
o Net energy change
o Energy state of products vs. reactants
Cellular Respiration – Ch. 9
**Know all key vocabulary and understand the following:
o Know all three phases of cellular respiration – know what goes into each phase and what
comes out of each phase.
 How much ATP is produced by each phase of cellular resp.
 From one molecule of glucose know:
o How many ATP are produced (in each phase)
o How many carbon atoms enter each phase (glycolysis/Citric acid/ETC)
o
 How is ATP produced – specifically (proton gradient etc…)
 Evolution of cellular energy – what stages evolved first?
 What is chemiosmosis and how does it occur in the mitochondria?
 What happens during glycolysis?
 Why is ATP a good energy source for organisms?


Know the job of each of the following (in terms of electrons)
o FADH2
o NADH
o Oxygen (why is oxygen so important??)
 Know their oxidized and reduced forms, which one has more energy
etc…H
What is reduced and what is oxidized during cellular respiration?
What is chemiosmosis?
What is oxidative phosphorylation?
Where does glycolysis take place?
What are the two types of fermentation.
o Under what conditions does fermentation take place?
o What are the products of both types of fermentation.
Which pathway is common to both fermentation and cellular respiration?
Where in the mitochondria does the ETC take place?
Where is ATP synthase located – specifically in the mitochondria?
Photosynthesis – CH. 10

Know the function and reactants/products of the light reactions and where does it take
place

Know the function and reactants/products of the Calvin Cycle and where it takes place

What does Chlorophyll do – how does it work?

If a leaf appears green, what colors are being absorbed/reflected??

Where does the Oxygen released during photosynthesis originally come from?

How is the energy of visible light used by the plant – what does it do?

Understand the relationship between photosynthesis and respiration – similarities and
differences etc…I suggest making a comparison chart to study.

Where is the electron transport chain located in photosynthesis?

How many turns of the Calvin Cycle are needed to produce a glucose molecule?

Review section 10.4 in book and understand the process of photosynthesis used by C4
and CAM plants – understand why these are appropriate adaptations for the type of
plants that use these alternate methods of photosynthesis. Know some details about
how they are different from regular photosynthesis (pg. 58 in the study guide book is a
good review!!)
