The Citric Acid Cycle article on Khan Academy explains the steps and significance of this crucial process in cellular respiration.
Khan Academy
Learn how NADH and FADH2 contribute to ATP production. Discover how energy is released when electrons transition from high to low energy states, creating a proton gradient that drives …
Phases of the cell cycle - Khan Academy
The cell cycle can be thought of as the life cycle of a cell. In other words, it is the series of growth and development steps a cell undergoes between its “birth”—formation by the division of a …
Intro to photosynthesis - Khan Academy
Jul 17, 2016 · The Calvin cycle, also called the light-independent reactions, takes place in the stroma and does not directly require light. Instead, the Calvin cycle uses ATP and NADPH …
C3, C4, and CAM plants (article) | Khan Academy
How the C4 and CAM pathways help minimize photorespiration.
Khan Academy
Intro to redox in cellular respiration. Substrate-level vs. oxidative phosphorylation. Electron carriers.
Photorespiration - Khan Academy
In the diagram below, you can see a comparison between photorespiration and the normal Calvin cycle, showing how many fixed carbons are gained or lost when either 6 CO 2 or 6 O 2 …
Regulation of Krebs-TCA cycle (video) | Khan Academy
The citric acid cycle, always active to varying degrees, is crucial for ATP production. Acetyl-CoA enters the cycle, undergoes oxidations, and exits as carbon dioxide, producing FADH2 and …
Khan Academy
The Krebs cycle occurs in the mitochondrial matrix, where pyruvate is turned into acetyl-CoA, which then goes through a series of reactions, producing ATP, NADH, and FADH2. Finally, …
