Document Summary
Redox reactions electron transport chain"s generate a hydrogen gradient across the membrane. Three phases: carbon xation, reduction, generation of co2 accepted. Photorespiration- o2 substitutes for co2 in the active site of the enzyme rubisco. Photosynthetic rate is reduced (closed stomata) costs atp. C4 plants minimize the cost of photorespiration by incorporating co2 into for carbon compounds and mesophyll cellshey. Cam plants: open this someone at night and bring in co2 to make organic acids. Intermembrane space: holds the proteins that transports protons electrons. Electron transport chain allows the proton gradients to build with hydrogen ions. Atp synthesis pumps the hydrogen ions down into the matrix reacting the.
