Is aerobic respiration of glucose endothermic or exothermic?
Exothermic
What dose ATP stand for?
Adenosine Triphosphate
ATP has 3 phosphate bonds which are unstable (they have a low activation energy which means they are easily broken). When they do break they release a large amount of energy.
Once ATP is made it diffuses into the part of the cell that needs energy. The energy is released via a hydrolysis reaction which breaks ATP down into ADP (adenosinediphosphate) and inorganicphosphate (Pi)
ATP +H2O ⇌ ADP + Pi + energy
ATP cannot be stored or transported between cells so has to be made continuously in the mitochondria of cells when required.
The inorganic phosphate released during the hydrolysis of ATP can be used to phosphorylate other compounds, often making them more reactive.
