Topic 1: 200• Question:• The chemical energy used for most cell

processes is carried by _________• Answer• Adenosine Triphosphate

Topic 1: 400• 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

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

Topic 1: 800• Question: How do consumers produce ATP?

How is energy released from ATP?

• Answer• Digestion of food. Removal of phosphate

group.

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

Topic 2: 200• Question:• What is the basic definition of

photosynthesis?• Answer• A process that captures energy from sunlight

to make sugars that store chemical energy

Topic 2: 400• Question:• Why is chlorophyll important? What are two

kinds of chlorophyll?• Answer• It is a molecule in chloroplasts that absorbs

energy in visible light• A and B

Topic 2: 600• Question: What are the disc shaped parts of

the chloroplast? What is the whole stack called? What is the gray space known as?

Topic 2: 800• Question:• Send someone to the board to write the

chemical equation of photosynthesis • Answer

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

Topic 3: 800

Topic 3: 1000• 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.

Topic 4: 200• Question:• What does ATP synthase mean? What does it

do?• Answer• Enzyme that makes ATP. Adds a phosphate

group to ADP

Topic 4: 400• Question: Where do light-dependent

reactions occur?• Answer

Topic 4: 600• Question:• The light dependent reactions require what

reactant? How is that reactant used?

• Answer

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

Topic 4: 1000• Question:• Describe all the steps of the Calvin cycle

• Answer
