11.3 the light- independent reaction Flashcards
1
Q
describe the events in the Calvin cycle (7)
A
- CO₂ + RuBP breaks into 2 GP by reduction
- catalysed by Rubisco
- GP converted to TP
- NADPH provides H⁺
- ATP provides energy
- from Pi from ATP
- for regenerating RuBP
2
Q
explain how the chloroplasts are adapted to carry out the light-independent reaction. (3)
A
- stromal fluid contains all the enzymes needed to carry out the LIR
- stromal fluid surrounds grana so ATP and NADPH can diffuse readily
- contains DNA and ribosomes so can quickly and easily manufacture proteins for the LIR
3
Q
what is RuBP short for?
A
ribulose bisphosphate
4
Q
what is GP short for?
A
glycerate 3- phosphate
5
Q
what is TP short for?
A
triose phosphate
6
Q
what is the light independent reaction also called?
A
Calvin cycle
7
Q
which co-enzymes are involved in photosynthesis?
A
NADP
