Oxidative phosphorylation Memes

The cellular respiration gang shows up uninvited to every biology course like clockwork. Just when you think you've escaped glycolysis, the Krebs cycle, oxidative phosphorylation, and their sidekick PPP (pentose phosphate pathway) appear at your door with that "we're back" energy. The look of exasperation from Steve Harrington perfectly captures the collective sigh of every biology student realizing they'll be drawing those same metabolic pathways for the fifth time. The mitochondria might be the powerhouse of the cell, but these pathways are the powerhouse of academic suffering.
