Cellular respiration -is the main way that chemical energy is harvested from food and converted to ATP energy. Cellular resp uses Oxygen meaning it is an anaerobic process. The chemical equation for cellular respiration is 6O2 + C6H12O6 --> 6H2O + 6CO2 + energy The first step in cellular respiration is called Glycolysis. In this step 6 carbon glucose molecule is broken in half. The second step is called The citric acid cycle and the final step is called Electron Transport.
Photosynthesis- method of converting sun energy into chemical energy usable by cells called glucose.Photosynthesis takes place in specialized structures inside plant cells called chloroplasts.The chemical equation for photosynthesis is 6CO2 + 12 H2O + light energy C6H12O6 + 6O2+ 6H2O. There are two stages in photosynthesis. The first is called Light reactions, where solar energy is converted into chemical energy. the second stage is called calvin cycle where sugars are made from carbon dioxide.
Connection/similarities/ differences. photosynthesis provides the oxygen that cellular respiration needs to begin. in return using that oxygen, cellular respiration converts it into CO2, which photosynthesis needs to start & produce the oxygen SIMILARITIES - Both involve electron transport chains. - Chemiomosis allows ATP synthase to produce ATP. - Both take place at some point within an organelle (mit. = CR, chloroplast= photo.) - Both utilize ATP for energy at some points. - Both provide power for cellular activities. DIFFERENCES -Cellular respiration depends on oxygen as a substrate. -Photosythesis utilizes 2 electron transport chains (not just 1). -Photosynthesis involves the production of NADPH (CR involves NADH and FADH2) -Photosynthesis involves CO2 and H20 as substrates (splitting h20 provides the electrons for the process).
