The Krebs Cycle and Electron Transport Chain If oxygen is available, pyruvate enters the mitochondria to undergo the Krebs cycle, also known as the citric acid cycle. Each stage plays a specific role in dismantling the nutrient molecule and capturing energy.
Glycolysis, Krebs Cycle, and Electron Transport Chain Stages
These electrons then move to the electron transport chain, a series of proteins embedded in the mitochondrial membrane that creates a proton gradient to drive the synthesis of the majority of the cell's ATP. Here, carbon atoms are stripped away to form carbon dioxide, and high-energy electrons are harvested.
Understanding these stages is essential to grasping the full meaning of the term. Without this constant conversion of fuel into energy, life as we know it would cease instantaneously.
Understanding the Krebs Cycle and Electron Transport Chain
In this comparison, the nutrient molecule is the raw fuel like coal, the mitochondria act as the generator, and ATP is the electricity that powers the city. Glycolysis: The Initial Split The journey begins in the cytoplasm with glycolysis, where a six-carbon glucose molecule is split into two three-carbon pyruvate molecules.
