複選題37. Regarding to cellular energetics which statement is (are) CORRECT? (A) Cells convert external sources of energy, sunlight or chemical nutrients, into a biologically universal intracellular chemical energy carrier, adenosine triphosphate (ATP), through aerobic oxidation or photosynthesis. (B) In the process of aerobic oxidation, cells convert the energy released by the oxidation of glucose or fatty acids into ATP, which is regulated by the demands of cells. (C) Most eukaryotes can generate a small amount of ATP when oxygen is scarce, a process called fermentation. (D) In most eukaryotic cells, oxidation of very long-chain fatty acids occurs in mitochondria with production of ATP. (E) Reactive oxygen species (ROS) are toxic by-products of glycolysis that can modify and damage proteins, DNAs and lipids.
