I've been reading about how mitochondria are often called the powerhouse of the cell, but I wonder if our traditional focus on energy production overshadows their role in other processes like apoptosis or calcium signaling. In my biology class last semester, we spent weeks on the electron transport chain but barely touched on how mitochondrial dysfunction affects neurodegenerative diseases. Could it be that we need to rethink how we teach cellular biology to better reflect the complexity of these organelles?
