01
Why Pathways Matter
Why every clinician and researcher should think in pathways, not isolated molecules.
02
Reading Pathway Diagrams
Arrows, T-bars, dashed lines — what they mean and where they lie.
03
Glycolysis & the TCA Cycle
The two engines of central carbon metabolism — and why both matter at the bedside.
04
Oxidative Phosphorylation
Electron transport chain, proton-motive force, and the small drugs that uncouple them.
05
Lipid & Amino Acid Metabolism
Beta-oxidation, ketogenesis, urea cycle, and the bedside-relevant inborn errors.
06
Signal Transduction Basics
GPCRs, second messengers, and the universal grammar of cell signaling.

Built for medical professionals and researchers.

Every claim is graded A–F. Every module ends with quiz items, flashcards, and pointers into the curated Pathway Atlas — search 100+ pathways, intersect molecules with enzymes, or browse by category.
