ATP Synthase: Proton-powered Rotation

The video tutorial explains ATP synthesis, highlighting its importance as the primary source of ATP under aerobic conditions. It details the role of proton pumps in creating an electrochemical gradient and how ATP synthase uses this gradient to produce ATP. The structure of ATP synthase, including its alpha, beta, and gamma subunits, is discussed, along with the mechanism of proton movement and subunit rotation. The tutorial concludes with an explanation of the conformational changes in ATP synthase that facilitate ATP production.
