Where Is ATP Made in Cells?
ATP is made in our cells by capturing some of the energy released from
energy molecules when they are broken down in energy pathways. Most
of the ATP made in our body is made in mitochondria (singular: mito-
chondrion). For this reason mitochondria are often referred to as the
"powerhouses" of our cells. A relatively small portion of the ATP gener-
ated in our cells each day will be made in the intracellular fluid outside the
mitochondria. As you might expect, cells with higher energy demands
will have more mitochondria. This is certainly true for heart and skeletal
muscle cells and cells within our liver.
