• What is cellular respiration and what are its three stages?
This process takes the food we eat and turns it into energy that can be used by the cells called Adenosine Triphosphate (ATP). The three stages : 1) Glycolysis 2) Citric acid cycle 3) Electron Transport Chain (ETC)
• What is the role of glycolysis? Include the reactants and the products. Where does it occur?
Is the first step used to breakdown the glucose.
The reactants are two molecules from glucose pyruvate, 2 ATP molecules, 2 molecules of NADH, and 2H..
The product is a glucose molecule with 2 phosphate groups that make glucose less stable.
Glycolysis occurs in the cytoplasm.
• What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur?
The citric acid cycle is to gather high energy electrons from carbon fuels.
The citric acid produces: 6 NADH, 2 FADH2, 2 ATP , and 4CO2
This action takes place in the mitochondria
• What is the role of the electron transport system? Include the reactants and the products. Where does it occur?
The role of the electron transport is basically to take carry electron from glucose to oxygen, and then forming water (H20) with the addition of hydrogen. It does this by taking electron from NADH and using a chain of molecules with the downward gravity pull of oxygen. As the electrons travel down the chain some of their energy gets reused for ATP.
The reactants in the Electron transport system are: H ions, O2, NADH, and FADH2 The products are: H2O and ATP The process happens in the cristae .
