More energy is captured during the catabolic oxidation of an 18-carbon fatty acid than the catabolic oxidation of three 6-carbon glucose molecules because: a. glucose oxidation captures energy in the form of FADH2 whereas fatty acid oxidation captures energy in the form of ATP b. a fatty acid is at a higher energy point on the oxidation series of carbon than glucose c. a fatty acid is a more reduced substance than glucose which is partially oxidized d. the oxidation of an 18-carbon fatty acid produces 9 acetyl CoA molecules that go through the TCA Cycle, whereas the oxidation of three 6-carbon glucose molecules produce 6 acetyl CoA molecules that go through the TCA cycle e. energy capture from glucose oxidation is only 15% efficient whereas energy capture from fatty acid oxidation is 42% efficient
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.
More energy is captured during the catabolic oxidation of an 18-carbon fatty acid than the catabolic oxidation of three 6-carbon glucose molecules because:
a. glucose oxidation captures energy in the form of FADH2 whereas fatty acid oxidation captures energy in the form of ATP
b. a fatty acid is at a higher energy point on the oxidation series of carbon than glucose
c. a fatty acid is a more reduced substance than glucose which is partially oxidized
d. the oxidation of an 18-carbon fatty acid produces 9 acetyl CoA molecules that go through the TCA Cycle, whereas the oxidation of three 6-carbon glucose molecules produce 6 acetyl CoA molecules that go through the TCA cycle
e. energy capture from glucose oxidation is only 15% efficient whereas energy capture from fatty acid oxidation is 42% efficient
