Mitochondria
Mitochondria supply the energy in the cell.
Heart muscle cells have the most mitochondria, thousands per cell.
High-intensity interval training in aerobic exercises such as biking and walking cause cells to make more proteins for their energy-producing mitochondria, effectively stopping aging at the cellular level.
What would happen if all the mitochondria in your body released all their energy at once?
This is an interesting piece on mitochondria
Thanks! I understand that there’s more in each cell of the heart than any other cell of the body.
