light independant reactions

Question 1

Where does this take place?

Answer 1

= this takes place in the stroma

Question 2

What does this use?

Answer 2

= carbon dioxide
= reduced NADP
= ATP

Question 3

What happens first?

Answer 3

= ribulose bisphosphate (rubh) 5 carbons
= reacts with co2- this is an co2 acceptor 6 carbons , and is catalysted by the enzyme rubisco
= this forms 2 molecules of glycerate 3 phosphate, splits, as it is unstable- a 3 carbon molecule
=

Question 4

What happens in the next stage?

Answer 4

= glycerate 3 phosphate is reduced into triosphoshate using energy from ATP and the hydrogen from reduced NADPH- so this is oxidised
= there are 2 triosphosphate
=spme of the carbon from tp leaves tge cycle each turn to convert into useful organic substances
= cycle happens 6 times, 6 carbons haev been removed and this forms hexose sugar
=
= the rest of the molecule is used to regenerate rubp, with the energy from ATP, requires ATO
=

Question 5

What is formed?

Answer 5

= the monoscharide can join together to form dissacharides, such as surcrose, maltose and lactose, or polysacharides
= or can be stord
