Here, we shall discuss aerobic respiration. The reaction occurs twice for each molecule of glucose, as there are two pyruvates and hence two molecules of Acetyl CoA generated to enter the citric acid cycle. It is observed in both plants and animals and the end product of this type of respiration is water and Carbon dioxide (CO2). The overall reaction is as follows: 2 (ACETYL COA + 3 NAD+ + FAD + ADP + PI → CO2 + 3 NADH + FADH2 + ATP + H+ + COENZYME A). Aerobic and Anaerobic Respiration - There are two types of cellular respiration- they are aerobic respiration and anaerobic respiration. The table below is an “ATP account” for aerobic respiration, and shows that 32 molecules of ATP are made for each molecule of glucose used in aerobic respiration. This process of glycolysis produces energy – 2 ATP molecules and 2 NADH (Nicotinamide Adenine Dinucleotide) molecules. The word respiration is derived from the Latin ‘respirare’ meaning to breathe. anaerobic respiration definition: 1. a chemical process in which energy is produced from food without using oxygen, for example by…. Aerobic respiration occurs in the mitochondrial matrix of the cell. This is how alcoholic drinks and bread are made. The electron transport chain, where the majority of ATP is formed, requires a large input of oxygen. (2016, October 23). Where does the citric acid cycle take place?
