Universal energy currency
energy is required for many biological processes
three main types:
syntheses of large molecules
transport of molecules
movement of an organism
this energy required is supplied by adenosine triphosphate (ATP
ATP is composed of three phosphate molecules, a pentose sugar and the nitrogenous
base, adenine
ATP is known as the universal energy currency because it is used for energy transfer in
all living things
How ATP releases energy
energy is required to break bonds and is released when bonds are formed
some energy is required to break a weak bond between one of the phosphate molecules
however lots of energy is released when a bond is formed to add the phosphate group
back on to the molecule, around 30.6 KJ/ mol is released
