How is the energy in our bodies converted into for example muscle movement

In: Biology

Electron transport chain (ETC). The ETC pumps hydrogen into one side of of a cell wall and electrons onto another side. To get energy a protein allows a hydrogen to pass through but extracts energy using the gradient. It’s like a little motor turning to extract energy in the form of ATP. ATP has a bond that holds energy and is easily broken. The bond releases energy when broken. This energy is used by cells to do what they need to do
