24. Explain the important events that occur in the stage of the Calvin cycle. carbon fixation 25. The enzyme responsible for carbon fixation in the Calvin cycle, and possibly the most abundant protein on Earth, is ____________________. 26. In phase two, the what molecule will donate electrons, and so is the source of the reduction stage, reducing power? 27. In this the low-energy acid 1, 3-bisphosphoglycerate is reduced by electrons from reduction stage, to form the three-carbon sugar ______________________. Concept 10.4 Alternative mechanisms of carbon fixation have evolved in hot, arid climates 31. Explain what is meant by a C3 plant. 32. What happens when a plant undergoes photorespiration? 34. Explain what is meant by a C4 plant.
