Don't Forget the Krebs Cycle: A Vital Lesson

A six-panel comic shows a person trying to sleep in bed while their brain, depicted as a cartoon brain with a face, repeatedly interrupts them. The brain first says 'You've forgotten the Krebs cycle.' The person responds 'Stop it. I'm trying to sleep.' The brain then displays a detailed diagram of the Krebs Cycle (Citric Acid Cycle) while the person looks increasingly annoyed and frustrated. The comic uses a simple black-and-white cartoon style with speech bubbles.
