Exercise as Housecleaning for the Body
The New York Times
February 1, 2012
By Gretchen Reynolds
It’s long been known that cells accumulate flotsam from the wear and tear of everyday living.
Broken or misshapen proteins, shreds of cellular membranes, invasive viruses or bacteria, and
worn-out, broken-down cellular components, like aged mitochondria, the tiny organelles within
cells that produce energy, form a kind of trash heap inside the cell.
In most instances, cells diligently sweep away this debris. They even recycle it for fuel. Through a
process with the expressive name of autophagy… cells create specialized membranes that engulf
junk in the cell’s cytoplasm and carry it to a part of the cell known as the lysosome, where the
trash is broken apart and then burned by the cell for energy.
Without this efficient system, cells could become choked with trash and malfunction or die. In
recent years, some scientists have begun to suspect that faulty autophagy mechanisms contribute
to the development of a range of diseases, including diabetes, muscular dystrophy, Alzheimer’s
and cancer. The slowing of autophagy as we reach middle age is also believed to play a role in
aging.
6. What is “autophagy?”
7. By what method do lysosomes patrol the cell and fuse with worn organelles?
8. Certain cells in your body are more metabolically active than others. Name 2 cell types in
the human body that would be most affected by “the wear and tear of everyday living.”
9. Describe a method where a research scientist might test how cancer can arise from faulty
autophagy. What organelles and cellular systems might the researcher study and why?
