Nitrogen Disposal

This process refers to the replacement of older proteins as they are broken down within the cell. What is being described?

Protein Turnover

For protein degradation, what enzyme is used that is considered non-selective?

Lysosomes

This process is a cellular housekeeping process that removes damaged organelles and protein aggregates. What is this process?

Autophagy

Ubiquitin is bonded to the C-terminal of what amino acids that form a isopeptide linkage?

Glycine and Lysine

The proteins are hydrolyzed through a series of enzymes before it reaches the intestines. Why is it that they need to be hydrolyzed?

Too large to be absorbed

There is an endopeptidase that gets activated with the presence of hydrochloric acid. What is being activated?

Pepsin

A serine protease is synthesized to convert a zymogen to trypsin. What protease is this?

Enteropeptidase

The carbonyl group is cleaved by trypsin by amino acids. What are those amino acids that contribute to this?
