6. 1 photosynthesis and cellular respiration provide energy for life. I(cid:374) photos(cid:455)(cid:374)thesis, whi(cid:272)h takes pla(cid:272)e i(cid:374) a pla(cid:374)t (cid:272)ell"s (cid:272)hloroplasts, the e(cid:374)erg(cid:455) of su(cid:374)light is used to rearrange the atoms of carbon dioxide (co2) and water (h2o) to produce sugar and oxygen o2. In cellular respiration, o2, is consumed as sugar is broken down to co2 and h2o; the cell captures the energy released in atp: takes place in the mitochondria in almost all eukaryotic cells. Chemicals are recycled between the two reactions. 6. 2 breathing supplies o2 for use in cellular respiration and removes co2. Breathing refers to an exchange of gases: an organism obtains o2 from its environment and releases co2, as a waste product. Cellular respiration: aerobic (oxygen requiring) harvesting of energy from food molecules by cells. 6. 3 cellular respiration bank energy in atp molecules. You breathe air and eat food to supply your cells with the reactants for cellular respiration the process the generates atp for cellular work.
