Photosynthesis Light Independent & Nutrient Transport Flashcards
what is the cycle for light independent reactions
the Calvin cycle
what is the first phase of the Calvin cycle called
carbon fixation
what is phase two of the Calvin cycle called
reduction
what is phase three of the Calvin cycle called
regeneration
what happens in carbon fixation
the enzyme RuBisCO adds CO2 to RuBP
what happens in reduction
energy from ATP and electrons from NADPH are used to produce glycerol-3-phosphate (G3P)
what happens in regeneration
ATP is used to regenerate RuBP
where does the energy come from for the Calvin cycle
ATP and NADPH from the light dependent reactions
what is the function of the xylem
it transports water upwards
what is the function of the phloem
transports sugars from sources to sinks
how does energy flow from light to sugars
photosynthesis and from sugars to ATP via cellular respiration
how many CO2 enters per Calvin cycle
3 CO2
