Light independent stage Flashcards
what is the calvin cycle
a metabolic pathway of the light independent stage, occuring in the stroma where co2 is fixed with products of light dependent stage to produce organic compounds
where does calvin cycle take place
stroma
How many RuBP and carbon dioxide is required to make 12 glycerate phosphate
6RuBP.
6CO2
How many carbons atoms are in RuBP
5
how many carbon is in 1 molecules of glycerate phosphate
3 carbon
what is the carbon fixation stage
when the enzyme RuBisCO catalysies 6 molecules of carbon dioxide to bind with 6 RuBP, to produce glycerate phosphate
what is the reduction stage pf the calvin cycle
The products of light dependent stage are reduced after glycerate phosphate is produced, to produce 12 triose phosphate from 12 GP.
ATP—- ADP + Pi
NADPH—— NADP
what is the product synthesis stage of the calvin cycle
when 2 molecules of triose phosphate are joined through condensation to produce 1 glucose molecules
Describe the difference in carbon atoms of triose phosphate and glucose
TP is a 3 carbon compound and glucose is a 6 carbon compound
how many triose phosphate molecules are required to produce one molecule of glucose
2 molecules of triose phosphate (3 carbon) needed to make on glucose ( 6 carbon)
what is the regeneration
10 triose phosphate molecules to make 6 RuBP molecules
what are the steps of the calvin cycle
1- fixation of carbon
2- reduction stage
3- product sysnthesis stage
4- regeneration stage
in the carbon fixation stage. what molecules need to enter the active site of RuBPisco
6 co2 and 6 RuBP
what are the yses if triose phosphate
tp can be used to synthesis amino acids, fatty acids, glycerol
Glucose is converted to starch and cellulose
