THE THREE-STEP CASCADE: STEP 1: RECEPTION Phytochemical binds receptor Receptor changes shape Signal initiated STEP 2: TRANSDUCTION Activated receptor triggers enzyme #1 Enzyme #1 activates enzyme #2 Enzyme #2 activates enzyme #3 Chain reaction continues Signal amplifies at each step STEP 3: RESPONSE Final enzymes reach targets Genes turned on/off Cellular function changes Timeline: Seconds Minutes Hours WHY CASCADES EXIST: Speed - Multiple enzymes work simultaneously Sensitivity - Small signals amplified to detectable levels Coordination - One signal, many related responses Flexibility - Can be modified at any step (synergy!) CLINICAL GOLD: Understanding cascades explains: 1
