Photolysis
Occurs in the grana of a chloroplast Solar energy (trapped by accessory pigments and chlorophyll) is converted into chemical energy. Photolysis of water: when H2O is split into hydrogen and oxygen by light energy. Produces Hydrogen, NADH and ATP (oxygen is the by product) Hyrdrogen and ATP used in next stage of photosynthesis (Carbon Fixation)
Carbon Fixation
Occurs in the stroma of a chloroplast. Enzyme controlled reactions occur in cycle. Carbon dioxide enters the cell by diffusion. Carbon Dioxide combines with a RuBP to form a 6-carbon molecule. 6-carbon molecule is unstable, so splits to form GP. GP is the converted into triose phosphate (by the hydrogen and ATP from photolysis) Triose phosphate is used in the regeneration of RuBP
Glycolysis
Occurs in the cytoplasm a 6-carbon glucose is broken down to form 2 molecules of 3-carbon pyruvic acid. requires 2ATP and produces 4ATP the first stage of respiration
Kreb's Cycle
Pyruvic acid (from Glycolysis) diffuses into the central matrix of a mitochondrion Pyruvic acid is converted into acetyl CoA 2-carbon acetyl CoA reacts with a 4-carbon compound and forms 6-carbon Citric Acid Hydrogen is the product, carbon dioxide is the waste product
