Metabolism | The Krebs Cycle

This video provides a comprehensive breakdown of the Krebs cycle, detailing each step, enzyme, and regulatory mechanism. It also explores the clinical relevance of enzyme deficiencies and mutations, linking metabolic pathways to disease.

• Learn a simple mnemonic to remember the intermediates of the Krebs cycle.
• Understand how citrate synthase forms citrate and is allosterically regulated.
• Learn how aconitase isomerizes citrate and is inhibited by fluoroacetate.
• Discover the first decarboxylation step producing NADH and CO2.
• Learn about the second decarboxylation step and its clinical significance.
• See how succinyl-CoA synthetase generates ATP via substrate phosphorylation.
