What is photosynthesis?
answer
The process in which producers use light energy to convert into glucose
question
What are the starting materials of photosynthesis?
answer
carbon dioxide, water, and light energy
question
What pigment is present in the highest amount in a chloroplast? What is its purpose?
answer
Chlorophyll is the pigment in the highest amount. Its job is to absorb light energy.
question
Are there other colored pigments in chloroplasts? If so, why are they important?
answer
Yes, there is also red, yellow, and orange pigments (cartenoids). They help absorb light that cholorphyll doesn't.
question
What are the end products of photosynthesis?
answer
Glucose and oxygen are the end products.
question
What are the 2 processes of photosynthesis? Where do they take place?
answer
The light reactions happens in the thylakoids, and the Calvin cycle happens in the stroma
question
Explain the three products that are made in the light reactions and where they go after they are made.
answer
Oxygen is the waste product made. It is transported out of the cell. ATP and NADPH are also made but transported to the Calvin cycle.
question
Why is it necessary for water to be split in the light reactions?
answer
Water is split to replace lost electrons in chlorophyll of photosystem I.
question
Where is glucose actually made?
answer
All of the glucose is made in the Calvin cycle.
question
What is sent back to the light reactions from the Calvin cycle?
answer
ADP and NADP+ are returned to the light reactions to be recycled.
question
BONUS REVIEW QUESTION: What is the difference between NADP+ and NADPH?
answer
NADP+ is an electron carrier. NADPH is the electron carrier that has the H+ ions and the electrons attached to it.
question
BONUS REVIEW QUESTION: What is the balanced equation for photosynthesis?
answer
6H20 +6CO2 (light)------> C6H12O6 + 6O2
question
BONUS REVIEW QUESTION: What color of visible light does chlorophyll absorb the best?
answer
Red and blue are absorbed the best.
question
BONUS REVIEW QUESTION: What color of visible light does not chlorophyll absorb at all? What happens to that color of light?
answer
Green is not absorb. It is either transmitted or reflected.
