Protein Recycling
Description
The process of protein degradation within the cell is critical for maintaining proper function and preventing disease. Discover how the ubiquitin system marks damaged or redundant proteins, siphoning them off for destruction inside the proteasome—the cellular structure that acts as a "protein shredder." This process allows the cell to eliminate toxins and recycle amino acids to build new proteins.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
