Photosynthesis Final Quiz Flashcards
How many times must the Calvin cycle run to create 1 glucose molecule?
6 times
What is the main difference between light dependant and light independent reactions?
Light dependant reactions absorb energy from the sunlight by the chlorophyll and store it.
Light independent reactions, the energy stored in light dependent reactions drives the assembly of sugar molecules from the carbon dioxide.
Where do light independent reactions take place?
Stroma
Where do light dependant reactions take place?
Thylakoid
What products from light dependant reactions are necessary for light independent reactions to occur?
NADPH and ATP
What major product is produced through light independent reactions?
High energy molecules (carbs)
What is PGA
Phosphoglyceric acid (3 carbon molecules)
Where in the chloroplast does the Calvin-Benson cycle occur?
Stroma
How many times must the Calvin cycle run to produce 1 glucose molecule?
6 times
What is glucose used for?
Make ATP for cellular respiration and Transport to other cells
Compare light independent reaction vs light dependant reaction
Light independent:
- Stroma
- creates ADP + Pi
- creates NADP+
- carbon dioxide in, then water, G3P/PGAL out
Light dependant:
- thylakoid
- creates ATP (ADP + pi)
- creates NADPH
- photolysis (water in oxygen out)
What are the factors that affect the rate of photosynthesis?
Carbon dioxide, water, sunlight, and chlorophyll
Photosynthesis rate with stomata?
plants with few and large stomata tend to have lower photosynthetic rate compared to those with many and small stomata
What is light independent reaction cycle known as?
Calvin benson cycle
