Photosynthesis Flashcards
1
Q
Role of NADP in light independent stage
A
reduces glycerate-3-phosphate to triose phosphate
2
Q
Effect on RuBP conc. if DCPIP gets reduced instead of NADP
A
RuBP conc. decreases as it reacts with CO2 to form (—>unstable intermediate ‘6C’); glycerate-3-phosphate and thus not regenerated
3
Q
Relation of Light Intensity and time to decolorize DCPIP
A
As Light Intensity Increases, time decreases because more Light energy absorbed by photosystem and electrons ejected faster making DCPIP reduce faster
4
Q
Why is the temperature kept low in redox indicator reaction involving chloroplast extract
A
to reduce the activity of enzymes and to prevent damage to chloroplast
