Cellular Respiration Steps For Dummies

Respiration is of two types aerobic respiration and anaerobic respiration.

Cellular respiration steps for dummies. Glucose is converted to pyruvic acid in the cytoplasm which is then used to produce acetyl CoA in the mitochondrion. Respiration which is more commonly referred to as breathing is the physical act of inhaling and exhaling. It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food.

Cellular respiration is what happens inside cells when they use oxygen to transfer energy from food to ATP. There are three main stages of cellular respiration. The steps of aerobic cellular respiration are.

Is the process in which sugars are broken down to form 2 pyruvates and 2 NADH Glycolyses Breakingsplitting of sugars Glyco Glucose Lyses to break - Occurs in the cytoplasm 2 ATP neededinvested in this step to form 4 ATP. In order to move from glycolysis to the citric acid cycle pyruvate molecules the output of glycolysis must be oxidized in a process called pyruvate oxidation. Glycolysis is an anaerobic process while the other two pathways are aerobic.

Electron transport chain or ETC. Aerobic respiration takes place in three phases Glycolysis Krebs Cycle and Oxidative Phosphorylation also called electron transport chain. The reaction is catalysed by citrate synthase.

The end result of these stages is ATP. Figure 6-1 provides an overview of cellular respiration. - These are made through substrate level phosphorylation.
