Document Summary
Atp is often referred to as the energy currency of the cell. The purpose of this lecture is to understand how much the cell can do with the hydrolysis of one atp molecule. Hydrolysis of atp under normal conditions: g0"=-7. 3 kcal/mol. Brownian motion and simultaneous motion of molecules in cells (random kinetic energy) Their movement is due to the transfer of kinetic energy acquired when one molecule runs into another. Molecules move and diffuse according to their size and have a diffusion coefficient d: smaller molecules diffuse faster due to less drag and acquiring more speed with kinetic energy. Understanding the magnitude of energy released by atp in the cell: setting the baseline. In order to draw comparisons between atp and other forms of energy, let"s compare it to the baseline, which is the amount of random kinetic energy naturally in physiological conditions. We can calculate the energy contained with this formula: E> = 3/2 kbt kb = boltzmann"s constant.
