Metabolism - ATP Synthesis, Mitochondria, Energy | Britannica
2024年10月6日 · When ADP and P i 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 P i to ATP.

2024年7月19日 · ATP is made via a process called cellular respiration that occurs in the mitochondria of a cell. Mitochondria are tiny subunits within a cell that specialize in extracting energy from the foods we eat and converting it into ATP.
Mitochondria, Cell Energy, ATP Synthase | Learn Science at Scitable
Mitochondrial genes that have been conserved across evolution include rRNA genes, tRNA genes, and a small number of genes that encode proteins involved in electron transport and ATP synthesis.
19.2: ATP Synthesis - Biology LibreTexts
2023年12月10日 · The mechanism by which the proton gradient drives ATP synthesis involves a complex coupling of the F o and F 1 subunits. Proton translocation occurs through the interface of the inner mitochondrial (or cell membrane of bacteria) membrane proteins C1 and A (or beta), whose structures from the bovine enzyme are shown again in Figure \(\PageIndex ...

How the Proton Gradient Drives ATP Synthesis. The electrochemical proton gradient across the inner mitochondrial membrane is used to drive ATP synthesis in the critical process of oxidative phosphorylation (Figure 14-14). This is made possible by the membrane-bound enzyme ATP synthase, mentioned previously. This enzyme creates a hydrophilic ...

2015年4月4日 · The ATP synthase is a molecular motor composed of two separable parts: F 1 and F o. The F 1 portion contains the catalytic sites for ATP synthesis and protrudes into the mitochondrial matrix. F o forms a proton turbine that is embedded in the inner membrane and connected to the rotor of F 1.
