CH 6 CELLULAR RESPIRATION 6.1 Photosynthesis and cellular respiration provide energy for life Recall photosynthesis • Energy in sunlight is captured by chloroplasts • Atoms of carbon dioxide and water are rearranged • Sugar and oxygen are produced © 2015 Pearson Education, Inc. 6.1 Photosynthesis and cellular respiration provide energy for life • In cellular respiration, • sugar is broken down to carbon dioxide and water • the cell captures some of the released energy to make ATP • Cellular respiration takes place in the mitochondria of eukaryotic cells. • In these energy conversions, some energy is lost as heat. © 2015 Pearson Education, Inc.
