" Cellular Energetics" helps students understand respiration, photosynthesis, and fermentation through interactive assignments aligned with AP Biology Unit 3 and high school biology. Students explore unusual energy pathways, methane-producing archaea, sulfur bacteria, and organisms that can obtain energy from rocks and gases. Activities for students: Break down complex terms like chemoorganoheterotrophy and photolithoautotrophy into clear, understandable ideas Compare cellular respiration, phot
