Learn how cells generate energy by harnessing chemical reactions, with Professor Lindsay Turnbull from the University of Oxford
Energy in Cells - Chapter 4
Cells need energy to run their activities, which they obtain by harnessing chemical reactions. Join Lindsay Turnbull from the University of Oxford as she explains how one reaction - aerobic respiration - is perfect for supporting the energy-demanding lifestyles of active animals, like us.
Aerobic respiration ultimately relies on a chemical reaction between oxygen and hydrogen. This reaction is so explosive that humans used it to launch a rocket into space, but the cell mostly needs much smaller amounts of energy. Find out how cells have tamed this reaction by using it to turn a molecular turbine. The turbine then re-charges small molecular 'batteries', called ATP, which can deliver energy all around the cell.
