1) Cellular respiration takes place in the mitochondria of cells and in the cytoplasm. 2) Cellular respiration uses glucose made by plants during photosynthesis and tuns it into cellular energy (ATP) through a series of three chemical reactions. 3) The three chemical reactions of cellular respiration are called glycolysis, the electron transport chain and the Krebs cycle. 4) Oxygen must be available for cellular respiration to happen if it is not available, then fermentation will break down the glucose. Vocabulary Aerobic-(stem: aero=air) something that requires oxygen or air to work. Anaerobic-(stem: an=non) something that does not require oxygen to work. 602 + CSH12O6 → 6CO2 + 6H2O + Energy (you need to memorize the equation and know the The Cellular Respiration Equation: products and the reactants) The Steps of Cellular Respiration (sometimes called aerobic respiration because it requires oxygen) Step 1: Glycolysis Happens in the cytoplasm. Breaks the glucose in to pyruvic acid. A very small amount of ATP is made. Step 2: Krebs Cycle Happens in the mitochondria The Krebs cycle takes the pyruvic acid and breaks it down into carbon dioxide and ATP and high energy electrons through a series of reactions. A slightly bigger amount of ATP is made. Step 3: The Electron Transport Chain Happens in the mitochondria on the folds of the inner membrane. Uses the high energy electrons from the Krebs cycle to tum ADP into ATP which can then be used in the cell for energy. Oxygen is consumed and water is produced. If you run out of oxygen while working out, you must breath heavily to repay the oxygen debt. A very large amount of ATP can be made
Electron Transport Chain
The electron transport chain, also known as the electron transport system, is a group of proteins that transfer electrons through a membrane within mitochondria to create a gradient of protons that drives adenosine triphosphate (ATP)synthesis. The cell uses ATP as an energy source for metabolic processes and cellular functions. ETC involves series of reactions that convert redox energy from NADH (nicotinamide adenine dinucleotide (NAD) + hydrogen (H)) and FADH2(flavin adenine dinucleotide (FAD)) oxidation into proton-motive force(PMF), which is then used to synthesize ATP through conformational changes in the ATP synthase complex, a process known as oxidative phosphorylation.
Metabolism
Picture a campfire. It keeps the body warm on a cold night and provides light. To ensure that the fire keeps burning, fuel needs to be added(pieces of wood in this case). When a small piece is added, the fire burns bright for a bit and then dies down unless more wood is added. But, if too many pieces are placed at a time, the fire escalates and burns for a longer time, without actually burning away all the pieces that have been added. Many of them, especially the larger chunks or damp pieces, remain unburnt.
Cellular Respiration
Cellular respiration is the cellular process involved in the generation of adenosine triphosphate (ATP) molecules from the organic nutritional source obtained from the diet. It is a universal process observed in all types of life forms. The glucose (chemical formula C6H12O6) molecules are the preferred raw material for cell respiration as it possesses a simple structure and is highly efficient in nature.

The Steps of Cellular Respiration (sometimes called aerobic respiration because it requires oxygen)
Step 1: Glycolysis
Happens in the cytoplasm.
Breaks the glucose in to pyruvic acid.
A very small amount of ATP is made.
Step 2: Krebs Cycle
Happens in the mitochondria
The Krebs cycle takes the pyruvic acid and breaks it down into carbon dioxide and ATP and high energy electrons through a series of
reactions.
A slightly bigger amount of ATP is made.
Step 3: The Electron Transport Chain
Happens in the mitochondria on the folds of the inner membrane.
Uses the high energy electrons from the Krebs cycle to tum ADP into ATP which can then be used in the cell for energy.
Oxygen is consumed and water is produced.
