- light intensity
- temperature
2
Q
how does CO2 affect photosynthesis?
A
- low concentration
- low levels of RuBP to GP
- low levels of GP to TP
3
Q
how does light intensity affect photosynthesis?
A
- higher light intensity
- photosystems and pigments absorb more light
- higher levels of ATP and NADPred
4
Q
how does temperature affect photosynthesis
A
- enzymes used (eg RuBisCO) will denature at high temp - changes shape of active site
- proteins in chloroplasts denature
