What is cellular respiration equation

This energy comes in the form of "ATP" , or adenine triphosphate. It is important to know that the equation listed above is a summary equation.

The process of cellular respiration involves many different steps reactions to break down glucose using oxygen to produce carbon dioxide, water and energy in the form of ATP. The 6 carbon atoms present in a glucose molecule make it possible to form 6 carbon dioxide molecules. The 12 hydrogen atoms in the glucose make it possible for form 6 water molecules.

To balance the oxygen atoms for the reactant side, you need to count 6 atoms from the glucose. The process will produce 38 ATP molecules for every one glucose in Prokaryotes bacteria. The reason why eukaryotes produce the smaller amount of ATP is that they need to use energy to move the pyruvate from glycolysis needed for the Krebs cycle into the mitochondria.

This video gives a quick review of respiration and discusses a lab which tests how temperature can alter the rate of respiration in yeast. The process takes place more quickly in warm conditions because of greater movement of particles. What is the chemical equation for cellular respiration? Ernest Z. Feb 7, Mar 4, Explanation: It is important to know that the equation listed above is a summary equation.

This video gives a more detailed discussion of the topic of cellular respiration. Source: Wikimedia Aerobic respiration is the type of cellular respiration that requires the presence of oxygen.

Among all the types of cellular respiration it is the most efficient. Plants and animals carry out this kind of respiration; plants obtain the precursor molecules from photosynthesis while animals obtain them from the food they eat i. May range from 34 to 38 net ATP. What is the role of Oxygen in the process? Oxygen is an essential molecule in cellular respiration. But where does it exactly fit in the picture?

Basically, oxygen can be found at the end of the ETC during aerobic respiration where it accepts electrons while picking up protons in order to produce water molecules. When oxygen levels are depleted, electrons will be simply dispersed and the electron transport chain will discontinue.

Of course no ATP will be produced, causing the cease of some physiological functions in the cell. Lactic Acid Fermentation Source: Wikimedia Alternatively during a depletion of oxygen, the cell may undergo a process called fermentation and utilize an alternative pathway at the end of glycolysis. And instead of oxidative phosphorylation, it uses substrate level phosphorylation that does not require oxygen in the process this is not to be confused with anaerobic respiration.

Anaerobic Respiration. Anaeribic Respiration Source: Wikimedia This process occurs just like the typical cellular reaction same glycolytic and Krebs cycle pathway but only differs because it is used by organisms like bacteria and archaea where oxygen is not the final electron acceptor.

Rather, these organisms use sulfates or nitrates instead. It is important to note that while both fermentation and anaerobic happen in the absence of oxygen, the former is only an alternative and extends glycolysis to produce energy whereas the latter uses other molecules to complete the cycle as the organism will die in the presence of oxygen.

Unlike aerobic respiration that occurs in the mitochondria, aerobic respiration happens in the cytosol. The process of anaerobic respiration generates only 2 ATP per glucose molecule. Key References.
