importance of phosphorus compounds

• ATP- adenine, ribose, triphosphate

primary energy carrier in cells - provides energy for metabolic processes

synthesised throigh cellular respiration in in mitochondira and through photosynthesis in plants

phosphorlation in glycolysis- process of adding phosphates to glucose (hexose sugar), happens at the beginning of glycolysis and two ATP molecules go to making 3 ADP molecules where the Pi is then used in the glycolysis reaction - later in glycolysis is transferred back to ATP when hexose bisphosphate slits into two triose phosphates, each help turn two ADP molecules back into ATP by adding the phosphate ion back.

one importance of phosphate compounds in biological organisms would be in ATP (adenosine triphosphate). Composed of adenine, a ribose sugar, and three phosphate groups, which are bound by high energy bonds which release energy into the environment when broken. this energy produced when broken down is essential for processes such as active transport across membranes and muscle contraction. phosphrolalation reactions occur when phosphate groups are transferred and crucial in metabolic reactions such as glycolysis. In glycolysis reactions, glucose is phosphorilated by two molecules of ATP, which are broken down to produce ADP and a Pi (phosphate) ion. It is first phosporilated in glucose-6 and later in fructose-1, bisphosphate-6 which destablilises it, leading to its subsequent break down. Later in the pathway, ATP is regenerated through molecules such as bisphophoglycerate and phosphoenolpyruvate
