Draw a labeled diagrammatic presentation of ATP synthesis in Mitochondria
Answers
Answer:
draw using the refered image brainlist if it helped
Explanation:
The mechanism of ATP synthesis appears to be as follows. During the transfer of hydrogen atoms from FMNH2 or FADH2 to oxygen, protons (H+ ions) are pumped across the crista from the inside of the mitochondrion to the outside. Thus, respiration generates an electrical potential (and in mitochondria a small pH gradient) across the membrane corresponding to 200 to 300 millivolts, and the chemical energy in the substrate is converted into electrical energy. Attached to the crista is a complex enzyme (ATP synthetase) that binds ATP, ADP, and Pi. It has nine polypeptide chain subunits of five different kinds in a cluster and a unit of at least three more membrane proteins composing the attachment point of ADP and Pi. This complex forms a specific proton pore in the membrane. When ADP and Pi are bound to ATP synthetase, the excess of protons (H+) that has formed outside of the mitochondria (an H+ gradient) moves back into the mitochondrion through the enzyme complex. The energy released is used to convert ADP and Pi to ATP. In this process, electrical energy is converted to chemical energy, and it is the supply of ADP that limits the rate of this process.
