Oxidative Phosphorylation

Oxidative Phosphorylation

by Georgina Cornwall, PhD

This section will focus on the pathway with the highest net energy production: oxidative phosphorylation via the electron transport chain. Students will learn how fatty acids can feed into this pathway, which steps generate ATP, which steps consume ATP, and the by-products the cycle produces. This pathway is crucial for all aerobic organisms and is very high-yield on the MCAT exam.

Amazing lecture
By Peddi A. on 25. October 2023 for ATP Synthase

The video by Lecturio provides an excellent overview of the electron transport chain and chemiosmosis, two of the most important metabolic processes in the cell. These processes work together to produce ATP, the cell's energy currency. One of the most interesting things about the electron transport chain is that it is a highly efficient way to convert energy from food into ATP. The chain uses the energy from NADH and FADH2, two electron carriers that are produced during glycolysis and the Krebs cycle, to pump protons across the inner mitochondrial membrane. This creates a proton gradient, which is like a dam holding back a reservoir of energy. The ATP synthase enzyme then uses the energy of the proton gradient to drive the synthesis of ATP from ADP and inorganic phosphate. This process is called chemiosmosis. The video does a great job of explaining the complex steps of the electron transport chain and chemiosmosis in a clear and concise way. It also provides helpful animations and diagrams that illustrate the process.

awesome teacher
