megasheet - calvin cycle

calvin cycle - location

stroma of chloroplast

stroma characteristics (2)

low [H+], high ph (acidic)

stages of calvin cycle (3)

carbon fixation, reduction phase, regeneration of RUBP

carbon fixation characteristics

no ATP or NADPH needed

reduction phase characteritics (2)

+∆G - requires 2x more ATP than regeneration phase

regeneration of RUBP characteristic

+∆G - no NADPH needed

calvin cycle: carbon fixation - step 1

CO2 - removed from atmosphere, combined with RUBP by RUBISCO (enzyme)

calvin cycle: carbon fixation - step 2

organic molecules are transferred through the cycle by enzymes (reactant becomes product)

calvin cycle: reduction phase - step 1

NADPH and ATP - oxidized by electrons > energy used to reduce the organic molecule

calvin cycle: reduction phase - step 2

organic molecule transferred through the cycle by enzymes

calvin cycle - between reduction and regeneration phases

1 3C - exits cell to be used by glucose/other organic molecules

calvin cycle: regeneration of RUBP - step 1

remaining organic molecules - rearranged using ATP > creates more RUBP

calvin cycle: regeneration of RUBP - step 2

more RUBP - allows for continuation for calvin cycle

calvin cyle - per 1 glucose..

1 glucose molecule = 6 turns of calvin cycle
