WebThe mitochondrial respiratory rate is determined by demand, i.e., the rate of ATP utilization by the cell, while the cellular energy state at that demand level is determined by supply, i.e., activity of the dehydrogenases expressed as [NADH]/ [NAD+] and of cytoplasmic oxygen pressure. Publication types Research Support, U.S. Gov't, P.H.S. Review WebEnergy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis. Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation. The key steps of this process, shown in simplified form in the diagram above, include:

WebAbstract Proteolysis by cytoplasmic, energy-dependent proteases plays a critical role in many regulatory circuits, keeping basal levels of regulatory proteins low and rapidly removing proteins when they are no longer needed. In bacteria, four families of energy-dependent proteases carry out degradation. WebThe cytoplasm refers to the entire region of a cell between the plasma membrane and the nuclear envelope. It is composed of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals (see figure below). Even though the cytoplasm consists of 70 to 80 percent water, it nevertheless has a semisolid consistency. songs from the movie the graduate
