Respiration
infoWhy this? Respiration transfers energy from organic substrates to ATP, supporting energy-requiring cellular processes. Understanding aerobic and anaerobic pathways explains how cells meet changing energy demands and why oxygen availability affects ATP production.
scheduleWhy now? Following photosynthesis, we can compare two major energy-transfer processes using established knowledge of enzymes, membranes, and ATP. Respiration also completes the cellular foundation needed for ecosystem energy budgets and for later work on homeostasis and muscle contraction.
