Due to its high reactivity, phosphorus does not naturally exist as a free element. Phosphorus generally occurs as phosphate in minerals. Phosphate is typically found in the Earth’s crust at a concentration of about 1 gram per kilogram. WebThus, high-energy phosphate reactions can: provide energy to cellular processes, allowing them to run; couple processes to a particular nucleoside, allowing for regulatory control of the process; drive a reaction out of equilibrium (drive it to the right) by promoting one direction of the reaction faster than the equilibrium can relax. phillips brothers buffalo ny
