Completes the breakdown of glucose by oxidizing a derivative of pyruvate to carbon dioxide. proteins that play a key role in electron transport chains in mitochondria and chloroplasts The enzyme-catalyzed formation of ATP by direct transfer of a phosphate group to ADP from an intermediate substrate in catabolism. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use proteins that play a key role in electron transport chains in mitochondria and chloroplasts Process that does not require oxygen Process that does not require oxygen

Process that does not require oxygen electron carrier produced during the Krebs cycle The enzyme-catalyzed formation of ATP by direct transfer of a phosphate group to ADP from an intermediate substrate in catabolism. parent drug more polar metabolite

A catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end product, such as ethyl alcohol or lactic acid. Process that does not require oxygen electron carrier produced during the Krebs cycle parent drug more polar metabolite
