Photosynthesis is not quite as simple as adding water to CO2 to produce sugars and oxygen. A complex chemical pathway is involved, facilitated along the way by a range of enzymes and co-enzymes. The enzyme RuBisCO is responsible for "fixing" CO2 – that is, it attaches it to a carbon-based molecule to form a sugar, which can be used by the plant, releasing an oxygen molecule along the way. … WebThe theory relating the formation of ATP to electron flow in the membranes of both chloroplasts and mitochondria (the organelles responsible for ATP formation during cellular respiration) was first proposed by English biochemist Peter Dennis Mitchell, who received the 1978 Nobel Prize for Chemistry.

WebThere are two important adaptations that allow C4 plants to do this: First, C4 plants use an alternate enzyme for the first step of carbon fixation. This enzyme is called phosphoenolpyruvate (PEP) carboxylase, and it has no oxygenase activity and has a much higher affinity for CO2 than rubisco. As the name “PEP carboxylase” suggests, the ...
