Question:
What is meant when an organism is described as a “producer?”
Answer
An organism that produces its own energy from inorganic sources such as sunlight
Back

5. Topic 1: 600 Question: Explain the relationship between ADP and ATP
Answer
ATP is formed by adding an additional phosphate group to ADP. Adenosine Diphosphate to Triphosphate
Back

6. Topic 1: 800

7. Topic 1: 1000
Question:
How do lipids, carbohydrates, and proteins differ in ATP production?
Answer
Lipids provide more energy than carbs which provide the same as protein

Question:
Send someone to the board to write the chemical equation of photosynthesis
Answer
CO2+ H2O  (light, enzymes) C6H12O6 + O2

12. Topic 2: 1000
Question:
Overall is photosynthesis endothermic or exothermic? What are the two major stages of photosynthesis? In what significant ways do they differ?
Answer
Endothermic
Light-dependent/independent. One creates major energy carriers, one creates sugar

Question:
In what step of light-dependent reactions is active transport occurring? Passive transport? Describe the steps.
Answer
Active- step 3. ETC helps move hydrogen ions across the thylakoid membrane against the concentration gradient
Passive- Step 6. Diffusion of hydrogen ions across thylakoid membrane.

18. Topic 4: 200 Question: What does ATP synthase mean? What does it do?
Answer
Enzyme that makes ATP. Adds a phosphate group to ADP

21. Topic 4: 800
Question:
How is ATP (and NADPH) used in the Calvin cycle? Where did they come from (where were they made in the first place)?
Answer
They came from the light-dependent reactions.

28. Bonus Question: 2000 pts.
Briefly describe the 7 steps of light-dependent reactions.
1. energy from sun absorbed by cholorphyll, energized electrons enter ETC
2. water molecules split into protons, electrons, and oxygen. Electrons replace ones that left chlorphyll
3. ETC helps transport protons into thylakoid. Active transport
4. more sunlight
5. Electrons from ETC change NADP+ to NADPH
6. hydrogen ions diffuse out of thylakoid
7. ATP synthase makes ATP from ADP by adding phosphate group (get energy from chemiosmotic gradient in step 6)
