Question 31

What is P/O

Answer 31

The Phosphate/Oxygen Ratio, or P/O Ratio, refers to the amount of ATP produced from the movement of two electrons through a defined electron transport chain, terminated by reduction of an oxygen atom

dependent on the number of hydrogen ions transported outward across an electrochemical gradient, and the number of protons which return inward through the membrane via an enzyme such as ATP synthase
