Density of Water Water is most dense at 4 degrees and as it warms, it becomes less dense due to increased molecular motion associated with temperature increases. The high heat of vaporization enables organisms to use evaporation as a cooling mechanism because each gram of water that evaporates from the surface of an organism at 25 degrees C removes 580 calories of heat

The DGo for hydrolysis of ATP is dependent on the divalent ion concentration and pH, which affect the the stabilization and the magnitude of the charge states of the reactants and products. The charge density on the reactants is greater than that of the products Theoretical studies show that the products are more hydrated than the reactants

This process is known as a proton leak or mitochondrial uncoupling and happens because of the facilitated diffusion of protons into the matrix, mediated by a proton channel called thermogenin. As hydrogen ions are forced out of the complex the wheel revolves, allowing each of the three active sites on the synthase to convert one ADP molecule into an ATP molecule

Cellular respiration is therefore a process in which the energy in glucose is transferred to ATP.In respiration, glucose is oxidized and thus releases energy. Cells without oxygen available need to regenerate NAD+ from NADH so that in the absence of oxygen, at least some ATP can be made by glycolysis.To regenerate NAD+ from NADH, the electrons from NADH are added to pyruvate to produce alcohol (plants, yeast) or lactate (animals, bacteria).The total ATP yield of fermentation comes from glycolysis; 2 ATP molecules are produced per glucose

For example, cellular slime molds will generally live an individual unicellular life, but when starved will associate with one another to form a multicellular body (Bonner 2000; Hudson et al. This is particularly useful because ATP can undergo a type of chemical reaction called hydrolysis which will remove a phosphate group and release useful energy

These carrier molecules transport the high energy electrons and their accompanying hydrogen protons from the Krebs Cycle to the electron transport chain in the inner mitochondrial membrane. Aerobic respiration is divided into two processes: the Krebs cycle, and the Electron Transport Chain, which produces ATP through chemiosmotic phosphorylation

Fermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration.

By controlling enzyme activity a cell can control what reactions take place, because the types of reactions catalyzed by enzymes are extremely unlikely to occur spontaneously. While enzymes are designed to conserve free energy, some energy is always 'wasted' with each process (although endotherms use the 'wasted' energy to maintain body temperature)

It is an open question whether such emergent properties evolve only by chance, or whether they necessarily evolve in any large biogeochemical system, given the underlying laws of physics. This means that these reactions are readily reversible, simply by increasing the concentration of the products relative to the concentration of the reactants (for example, by increasing the proton gradient)

Two such proteins transport ADP and Pi from the cytosol to the mitochondrial matrix in exchange for ATP formed by oxidative phosphorylation inside the mitochondrion. Furthermore, there do not appear to be stable contacts between any two complexes; rather, electrons are transported from one complex to another only by diffusion of CoQ and cytochrome c, which act as electron shuttles (see Figure 16-19)
