Oxidative phosphorylation Memes

The cellular respiration gang shows up uninvited to every biology course like clockwork. First-year students thinking they're done with glycolysis after the first exam are met with the harsh reality that these metabolic pathways are the clingy exes of biology education. The Krebs cycle, oxidative phosphorylation, and their sidekick PPP (pentose phosphate pathway) keep reappearing semester after semester with increasing complexity. It's like trying to leave a party but the host keeps adding "just one more thing" about electron transport chains.

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.
