Which of the following molecular targets would lead to the greatest impact on the production of ATP in cellular respiration? A pharmaceutical that is similar to Acetyl-CoA leading to reduced CO2 being released during the citric acid cycle b. A pharmaceutical that limits the production of NAD+ and NADH c. A pharmaceutical that increases pyruvate oxidation d. A pharmaceutical that increases the activity of cytochrome c, part of the electron transport chain
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.
Please help with this practice question. I am not sure what the answer is. I believe it would be NAD+ and NADH production, but I am not sure.
During cellular respiration, a number of related metabolic reactions take place inside of cells to produce ATP. The main way that all living things, including humans, produce ATP, the main energy unit of the cell, is through cellular respiration. Glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain (ETC) are the three primary phases of cellular respiration.
