Glycolysis Where in the cell does glycolysis take place? GLYCOLYSIS O in the intermembrane space of the mitochondrion o inthe mitochondrial matrix O inthe cell membrane o inthe cytoplasm Glucose CHECK YOUR UNDERSTANDING 区 ADP ADP What is an outcome of glycolysis? O the breakdown of a pyruvate molecule into two smaller glucose molecules o the breakdown of a glucose molecule into two smaller pyruvate molecules o the breakdown of NADH into NAD* and high energy electrons o the breakdown of glucose into molecules of carbon dioxide NAD NAD Glucose NADH NADH ADP ATP ADP ATP NAD* e H* ATP ATP NADH NAD+ Glucose Net yield: 2 ATP and 2 NADH Pyruvate (2 molecules) CHECK YOUR UNDERSTANDING 区 Why does the breakdown of glucose net 2 molecules of ATP instead of 4? O because only 2 ADP molecules are available in the cytoplasm O because most of the energy from glucose is lost to the environment o because the breakdown of glucose requires an input of energy to begin O because all reactions require an input of energy Which one of the inputs has NOT been used by the process at this point? What outputs of the process have been produced at this point?
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.
