Chemiosmotic hypothesis

... Hypothesis is the proposal in 1961, by Peter D. Mitchell, that the mitochondrion functioned as a kind of electrochemical capacitor , using the energy of ... Peter Mitchell was awarded the Nobel Prize in Chemistry . see also: mitochondrion , chloroplasts , chemiosmotic potential , electron transfer chain , ...

Proton pump

... that is capable of moving protons across the membrane of a cell , mitochondrion , or other subcellular compartment, thereby creating a difference or ... transmembrane ATPase active transport cytochrome mitochondrion chloroplast electron transfer chain proton pump inhibitor ...

Adenosine triphosphate

... in the cytosol . Two molecules of ATP are generated for each molecule of glucose. The terminal stages of ATP synthesis are carried out in the mitochondrion and can generate up to 36 ATP. ATP in the human body The total quantity of ATP in the human body is about 0.1 mole . The energy used by ...

Apoptosis

... integrity, and massive activation of PARP-1 can deplete the cell of energy-providing molecules, an event that sends signals from the nucleus for the mitochondrion to start the apoptotic process. Homeostasis In the adult organism, the number of cells within an organ or tissue has to be constant within ...

ATP synthase

Cellular respiration

... Aerobic respiration requires oxygen . It is the preferred method of pyruvate breakdown. A molecule of pyruvate acid travels into a mitochondrion entering the Krebs cycle . In this process it is broken down producing energy in the form of ATP (which travels to the cell), NADH and FADH2 ...

Crista

... Cristae are the infoldings of the inner membrane of a mitochondrion . They are studded with proteins, including ATP synthase and a variety of cytochromes , and function in cellular respiration . They provide ...

Electron transfer chain

Phosphorylation

... prokaryotes as part of two-component signalling. Other kinds ATP , the "high-energy" exchange medium in the cell, is synthesized in the mitochondrion by addition of a third phosphate group to ADP in a process referred to as oxidative phosphorylation . ATP is also synthesized by substrate level ...
