AP Biology Unit 3: Cell Metabolics
Chapter 6: Metabolism
Compare anabolic to catolic reactions
Explain the relationship between potential and kinetic energy
State the first and second laws of thermodynamics
Explain/Sketch the induced fit (lock & key) model of enzymes
Describe the structure of ATP and ADP
List factors that affect enzymatic speed
Recognize names of enzymes and substrates (Ex. sucrose & sucrase)
Compare competitive to noncompetitive inhibition to feedback inhibition
Review the lab on hydrogen peroxide and enzymes, be able to write the reaction and explain how different factors affect the rate of reaction.
Chapter 7: Cell Respiration
Be able to write the equations for both cellular respiration and photosynthesis.
Describe the mitochondrion, be able to label specific structures within the mitochondrion.
With regard to respiration, summarize the events of glycolyss, the Krebs Cycle and the electron transport chain. Identify how much ATP is produced in each. Know where each of these processes take place.
Describe the membrane system that generates ATP, define the role of ATP synthase and concentration gradients in the process.
Discuss how fermentation is used in food production.
Chapter 8: Photosynthesis
Describe / Label the structure of a leaf.
Describe / Label a chloroplast and be able to identify where the major events of photosynthesis take place
Compare the action spectrum to the absorption spectrum
Discuss factors that influence the rate of photosynthesis
List the events that occur in the light reaction
List the events that occur during the light-independent reaction (Calvin Cycle)
Compare the events of photosystem I and photosystem II
Describe / label / sketch the events of the light reaction (see coloring)
Review lab on photosynthesis, understand how the design of the experiment allowed the rate of photosynthesis to be measured and what factors affected that rate.
Essential Questions: Respiration & Photosynthesis
- How do the processes of photosynthesis and respiration form a cycle?
- How does photosynthesis create food that is used for energy in cellular respiration?
- How is ATP generated by cells?
- Why is oxygen necessary and what happens when oxygen is not available to cells?
