Protein Metabolism: How Your Body Uses Protein for Energy & Growth

Did you know that proteins aren’t just for building muscle? While they play a crucial role in tissue repair, enzyme production, and immune function, your body can also break them down for energy when needed. But how does protein metabolism work, and what happens to excess amino acids?

In this final video of our three-part metabolism series, we explore:
✔️ How protein digestion and metabolism work
✔️ The process of deamination and nitrogen removal
✔️ How proteins contribute to energy production
✔️ The role of gluconeogenesis in protein metabolism
✔️ What happens to excess protein in the body

Topics Covered:
00:36 Protein Metabolism Overview
01:38 How Proteins Enter the Cell
01:56 Protein Catabolism
02:26 Deamination
02:46 Removal of Nitrogen waste
03:08 Energy metabolism
03:58 Gluconeogenesis
04:32 Protein Anabolism
05:06 Essential Amino Acids
05:22 Complete Protein
05:32 Incomplete Protein
05:55 What happens when excess proteins are consumed?
