Hamsters love to run exercise wheels. Prolonged running at a high rate of speed requires ATP. Coulda hamster with a defective gene for the enzyme lactate dehydrogenase meet the extra ATP demand forprolonged, fast wheel-running by maintaining a high rate of glycolysis? Why or why not? -No, not enough NADH can be regenerated for glycolysis to continue at a high rate -No, the defective gene will cause a rapid decline in pH in the muscles used for running -Both A and B -Neither A nor B Which of the following statements is correct? -The ketohexoses have fewer chiral carbon atoms than the aldohexoses -The reaction between one molecule of alcohol and one molecule aldehyde yields an acetal -Both A and B -Neither A nor B
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.
