Oxidation and Reduction in Cellular Respiration:
This Khan Academy video explains how oxidation and reduction reactions occur in cellular respiration. The chemical equation for cellular respiration is examined and broken down to show where each type of the reactions occur.
Oxidative Phosphorylation and Chemiosmosis:
This Khan Academy video explains how ATP is generated in the electron transport chain through the process of oxidative phosphorylation and chemiosmosis. It also explains the differences between oxidative phosphorylation and substrate level phosphorylation.
Cellular Respiration: Glycolysis:
This Khan Academy tutorial describes in detail the process of glucose being broken down into pyruvate during glycolysis. Glycolysis is the first biochemical pathway of cellular respiration.
Cellular Respiration: Kreb's Cycle:
This Khan Academy video describes how the pyruvate produced in glycolysis undergoes oxidation to produce Acetyl CoA. The video then explains what occurs when Acetyl CoA enters the Kreb's cycle and how NADH and FADH2 are produced.
Introduction to Cellular Respiration:
This Khan Academy video describes how energy is extracted from the glucose molecule to make ATP. Each biochemical pathway involved in cellular respiration is discussed.
How Glycolysis Works:
This animation shows the process of glycolysis. The reactants, products, and the basic functions of aerobic and anaerobic cellular respiration are identified.
This tutorial reviews the process of cellular respiration which is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP).
The Krebs cycle is the central metabolic pathway in all aerobic organisms. This tutorial will help the learners understand the Krebs cycle.
