Bio I
Test 6 Study Guide
What form of energy does food and ATP contain?
Define chemical energy
Where does the energy for photosynthesis come from?
Know the difference between autotroph and heterotroph
Difference between photosynthetic and chemosynthetic organisms, which are two types of autotrophs
Know the difference between herbivores, carnivores, and omnivores, which are different types of heterotrophs
What is the purpose of cellular respiration?
Why don’t living things use energy directly from food? Why do they have to use energy from
ATP?
What does ATP stand for and what are its structural components?
Remember adenine and ribose together is adenosine which is part of ATP
How does ATP store energy?
What type of bonds are between the phosphate groups in ATP?
How is energy released from ATP, and what is produced in this process?
Be able to explain the ATP-ADP cycle
What is phosphorylation?
Definition of photosynthesis
Definition of cellular respiration
Chemical equation for photosynthesis
Chemical equation for cellular respiration
Know what the reactants and products are in each equation
Explain how photosynthesis and cellular respiration are sort of the opposite of each other?
Know what the waste products are in each reaction
Is photosynthesis endergonic or exergonic?
Is cellular respiration endergonic or exergonic?
Where does the energy go that is released during cellular respiration?
Remember light is part of the electromagnetic spectrum
What is chlorophyll? What does it do?
Why is iron important for plants?
Why do plants appear green?
Does chlorophyll absorb green light?
Know how the different plant structures that we discussed in class are related
Know the other names for the light dependent phase
Where does the light dependent phase occur?
What happens in photosystem II, which is the first part of the light dependent phase?
Explain the process of chemiosmosis which is part of photosystem II
Where do electrons come from that replace the electrons that leave the special chlorophyll molecules in photosystem II
Where does the oxygen that’s produced through photosynthesis come from?
Remember the purpose of photosystem II is to produce ATP (chemical energy)
What happens in photosystem I, which is the second part of the light dependent phase?
Where do electrons come from that replace the electrons that leave the special chlorophyll molecules in photosystem I?

Remember the purpose of photosystem I is to produce NADPH (electron carrier)
Remember ATP and NADPH are products of the light dependent reactions that are used in the
Calvin Cycle
Be able to identify the different parts in the diagram for the light dependent phase
Know the other names for the Calvin cycle
Where does the Calvin cycle occur?
What happens in the Calvin Cycle?
Be able to label parts in the chloroplast
Know what stomata and guard cells are
Be able to interpret and explain the graph that shows light absorbance of chlorophyll a and b
