Define and explain the importance of "protein turnover."
What will be an ideal response?
Answers will vary.
Most vital body proteins are in a constant state of breakdown, rebuilding, and repair. This process, called protein turnover, allows cells to adapt to changing circumstances. For example, when we eat more protein than necessary for health, the liver makes more enzymes to process the waste product from the resulting amino acid metabolism-namely, ammonia- into urea. Overall, protein turnover is a process by which a cell can respond to its changing environment by increasing the production of needed proteins while reducing the production of proteins not currently needed.
