October 24, 2011 Biology 311C Lecture 25 To live is to transform energy. When you stop, you are dead. Cellular respiration is a form of energy transformation. In photosynthesis, it is also energy transformation except they can use light energy and convert it to chemical energy. The immediate product is ATP. Plants are the only creatures can do light reactions. In the Calvin cycle, it can take inorganic molecules (CO 2 ) and turn into something organic like sugar (CH 2 O). The light reactions provide ATP and NADPH to the Calvin cycle, and the Calvin cycle returns ADP, Pi, and NADP+ to the light reactions. ADP and NADP can go back to pick up more energy from the light reactions and deliver it to the Calvin cycle. The sugars reduced in the Calvin cycle can be converted to glucose and be exported to the mitochondria to create ATP. It can also combine to make starch for energy storage and also serve as the starting ground like triglyceride.
