What This Document Is
This document presents lecture material from MCB 2210 Cell Biology at the University of Connecticut, specifically focusing on the processes of cell aging and cell death. It explores the various mechanisms by which cells cease to function, and the biological significance of these processes within a larger organism. The lecture delves into the intricacies of cellular deterioration and programmed cell elimination, offering a foundational understanding of these critical life processes.
Why This Document Matters
