Photosynthesis Flashcards
1
Q
What is the equation for photosynthesis?
A
co2 + water (with light) = glucose + oxygen
2
Q
Where does photosynthesis occur?
A
Chlorophyll found in chloroplasts
3
Q
Name the uses of glucose in plants?
A
immediate energy soruce
stored as starch
used to make cellulose
4
Q
What is energy fixation?
A
Chlorophyll converting light energy into chemical energy
5
Q
What is photosynthesis?
A
A chemical process that takes place inside a plant, producing food for the plant to survive.
6
Q
What are the two stages of photosynthesis?
A
Photolysis (stage 1) and carbon fixation (stage 2)
7
Q
Explain photolysis?
A
- Water molecules split using light energy to produce oxygen and hydrogen. ATP and hydrogen are carried on to stage 2
- Its a light dependent stage
8
Q
Explain carbon fixation?
A
- Cycle of enzyme controlled reactions
- Is temperature dependent
- Hydrogen and co2 combine to form glucose
