Photosynthesis

Question 1

LIR (calvin cycle)

Answer 1

CO2 reacts with RuBP to form two molecules of GP (3 carbon compound)
This reaction is catalysed by Rubisco

GP is reduced to TP by energy from ATP and by accepting a H from reduced NADP

Some of the carbon from TP leaves the cycle each turn to be converted into useful organic substances and the rest is used to regenerate RuBP (with energy from ATP)

Glucose is the product but can form disaccharides such as sucrose

It can also be converted into glycerol and combine with fatty acids to make lipids for the plant

Question 2

LIR (calvin cycle)

Answer 2

CO2 reacts with RuBP to form two molecules of GP (3 carbon compound)
This reaction is catalysed by Rubisco

GP is reduced to TO using energy from ATP and by accepting a H from reduced NADP

Some of the carbon from TP leaves the cycle each turn to be converted into useful organic substances and the rest is used to regenerate RuBP (with energy from ATP)
