Lesson 19 — From Pyruvate to Power: PDC and Krebs Cycle Explained

Описание: You’ve learned how glucose breaks down in glycolysis…
Now it’s time to follow pyruvate’s next move — into the powerhouse of the cell. ⚙️🔥

In this lesson, we’ll guide you step-by-step through:
🔹 PDC (Pyruvate Dehydrogenase Complex): how pyruvate is converted into Acetyl-CoA
🔹 Krebs Cycle (Citric Acid Cycle): how Acetyl-CoA fuels the production of NADH, FADH₂, and ATP
🔹 The location of each process in the mitochondria
🔹 The molecules gained (and lost!) at each step
🔹 Real clinical links to conditions like thiamine deficiency and mitochondrial disorders

⸻

📌 By the end of this video, you’ll understand:
✅ Why PDC is the critical bridge between glycolysis and the Krebs cycle
✅ How energy-rich molecules are formed for the next stage (ETC)
✅ Where carbon dioxide is released — and why it matters
✅ The cycle’s connection to fat metabolism, exercise physiology, and disease

🧠 Made for first-year medical students, biology beginners, and anyone who wants ATP to finally make sense.

📽️ Watch now — pause, take notes, test yourself at the end, and come back whenever you need a refresh!
