Photosynthesis and Respiration

Photosynthesis and cellular respiration are ‘opposite’ reactions in the carbon cycle – one is endothermic (requires the input of energy) and one is exothermic (releases energy). Once you have read Chapter 3 and answered the chapter review questions, watch these videos and test your understanding by completing the “Photosynthesis/Respiration” worksheet. Whereas photosynthesis occurs only in the chloroplasts of plants, cellular respiration occurs in the mitochondria of both plants, fungi and animals. You will need to know these biochemical processes in a good deal of detail for the exam.
