Flavo Protein

From Wikipedia, the free encyclopedia

Flavo Protein is the first protein found on the Electron Transport Chain (ETC). In aerobic respiration, 1 glucose molecule can produce an average of 36 ATP (Adenosine triphosphate - stuff that you can use for energy). NADH+ molecules, which produce 3 ATP each, can enter through the Flavo Protein and pump H+ ions into the intermembrane space of the mitochondrion, thus causing a concentration gradient that ATP synthase can use to produce ATP (as the H+ ions get back in through the inner membrane, they release stored potential energy. ATP Synthase is also a protein on the inner membrane, and is the only way the ions can get back in, like a hole in a dam. ATP Synthase uses the released energy to catalyze a redox reaction, attaching a phosphate group to ADP, Adenosine diphosphate, thereby storing energy.)
