A set of metabolic reactions and processes that helps the organisms to convert chemical energy into adenosine triphosphate from nutrients or oxygen molecules is called cellular respiration. The catabolic reactions are involved in the respiration process that helps to break down large molecules into smaller particles. The visual representation of the known information either in the form of graphs or charts or tables or Venn diagrams. By analyzing the meaning of the concept map we will learn the definition of the cellular respiration concept map, it is a graphic representation of the complete process of cellular respiration. Let us see the cellular respiration map and analyze it by following the steps mentioned below. Steps Involved in Cell Respiration Concept MapDuring the process of cellular respiration, the glucose molecule is broken down into water and carbon dioxide. In the reactions that transfer glucose, some of the ATP molecules are produced along the way. But the maximum number of ATP is produced in the process called oxidative phosphorylation. A series of proteins are embedded in the mitochondria, the movement of the electrons takes place in the electron transport chain reaction during which oxidative phosphorylation occurs. The electrons that are traveled to the electron transport chain are directly derived from the glucose molecule by some of the electron carriers such as NAD⁺ and FAD and when the gain in the electrons takes place these carriers get converted to form NADH and FADH₂. In the cellular respiration map where ever it is mentioned as “+NADh and + FADH₂”, the molecules are not being added from the scratch instead they are being converted from the electron carriers. Equations: NAD⁺ + 2e⁻ + 2H⁺ → NADH + H⁺ FAD + 2e⁻ + 2H⁺ → FADH₂ We will see how the carbon dioxide is obtained from the glucose molecule and how the energy is harvested as NADH/FADH₂ and ATP. Cellular respiration consists of four stages, they include:
The final equation at the end of the cellular respiration is Glucose + Oxygen → ATP + Carbon dioxide + Water [Image will be Uploaded Soon] If the process of glycolysis takes place in the absence of oxygen it is called fermentation. Cellular respiration includes other three steps that require oxygen, they are pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation. Among these, oxygen is directly utilized only in the case of oxidative phosphorylation, but the remaining two processes are dependent on oxidative phosphorylation for the consumption of oxygen. Conclusion:The process which is used by all the living organisms in the formation of energy from glucose molecules is cellular respiration. While the autotrophs produce their own glucose molecules by the process of photosynthesis and the heterotrophs obtain their glucose from another organism. However, the process of cellular respiration is the collection of metabolic processes such as glycolysis, citric acid cycle or Krebs cycle, and electron transport chain. While moving from glycolysis to the citric acid cycle the pyruvate molecules obtained from glycolysis are oxidized by a process called pyruvate oxidation. Practice cellular respiration concept maps to understand the process easily and efficiently. Remembering the end products of each step involved is necessary as it can appear in the examination in the form of objectives.

Recently Updated Pages Recently Updated Pages What does cellular respiration often begin with?The process begins with Glycolysis. In this first step, a molecule of glucose, which has six carbon atoms, is split into two three-carbon molecules. The three-carbon molecule is called pyruvate. Pyruvate is oxidized and converted into Acetyl CoA.
What is the cell respiration equation?The equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy) You may notice that the equation for cellular respiration is the opposite of the equation for photosynthesis.
What is the role of oxygen gas o2 in aerobic cellular respiration?Oxygen serves as a final electron acceptor of the electron transport chain in cellular respiration assisting the movement of electrons down a chain, resulting in the production of adenosine triphosphate (ATP). Oxygen combines with electrons and hydrogen ions to produce water. Hence the importance.
What is the input for cellular respiration?The inputs, or reactants, of cellular respiration are glucose and oxygen. The outputs, or products, of cellular respiration are water, carbon dioxide and ATP molecules (which our body uses for energy). The glucose comes from the food we eat after our digestive tract has broken it down.
