In this lecture, EKG is going to cover nitrogen excretion via the urea cycle. We're going to break down how ammonia is transported from the muscles and other tissues to the liver, where it's converted to urea and excreted safely in the urine. Lastly, we'll break down the urea cycle and how the citric acid and urea cycle are linked.

Lecture Overview:
0:00 Intro
0:30 Amino Acid Degradation Review
2:40 Conversion of Ammonia To Glutamine
3:20 Transport of Ammonia From Skeletal Muscles (Glucose-Alanine Cycle)
4:41 Urea Cycle Process
7:05 How The Citric acid & Urea Cycle Are Linked

✏️ All diagrams were made by EKG.
