#1
Front (Question)

where?

Back (Answer)

stroma

#2
Front (Question)

• stage 1

Back (Answer)

• CO2 enters through stomata and diffuses into stroma of chloroplast • combined with ribulose bisphosphate (RuBP) 5 C compound and catalysed by enzyme rubisco • gives unstable 6 C compound which breaks into 2 molecules of 3 C compound glycerate 3-phosphate (GP)

#3
Front (Question)

• stage 2

Back (Answer)

• hydrolysis of ATP (from light dependent reaction) energy to turn 3C compound GP into different 3C compound triose phosphate (TP) • requires H+ ions which come from reduced NADP (recycled to NADP) • some TP is then converted into useful organic compounds e.g. glucose. some continues in calvin cycle to regenerate RuBP

#4
Front (Question)

• stage 3

Back (Answer)

5 out of every 6 molecules of TP produced in cycle are used to regenerate RuBP which uses rest of ATP from LDR

#5
Front (Question)

carbohydrates

Back (Answer)

hexose sugars (glucose) 2 x triose phosphate joined

#6
Front (Question)

lipids

Back (Answer)

glycerol (which is sythesies from triose phosphate and fatty acids) fatty acids synthesised from glycerate 3-phosphate

#7
Front (Question)

amino acids

Back (Answer)

glycerate 3-phosphate

#8
Front (Question)

how many turns of the calvin cycle make one hexose sugar (e.g. glucose)

Back (Answer)

6

#9
Front (Question)

why does it take 6 turns to make 1 hexose sugar

Back (Answer)

5 out of 6 TP molecules used to produce RuBp after 3 turns only 1 TP produced to make hexose sugar 2 TP molecules needed to form 1 hexose sugar
