Apoptosis pathways are a high-yield focus for the USMLE Step 1 because they regulate programmed cell death. This diagram maps the intrinsic pathways of apoptosis, highlighting BAX and cytochrome c release from the mitochondria. It also details extrinsic apoptosis pathways, showing the FasL-Fas interaction and cytotoxic T-cell activity. Understanding the convergence onto executioner caspases is critical for answering board questions on cellular injury and homeostasis. From nuclear fragmentation to macrophage engulfment, every step is visualized. This illustration uses color-coded flow logic to clearly map complex signaling cascades instead of providing a static list of labels.
