        Cellular Respiration In Scarce Oxygen: Hummingbird Adaptions at High Altitudes

        Learn how hummingbirds maintain their fast metabolism in low oxygen, high-altitude, conditions with super powered hemoglobin in this video from NATURE: Super Hummingbirds. In the accompanying classroom activity, students analyze hard data on the oxygen affinity of several hummingbird species and how that powers cellular respiration. The teaching tips describe how students can analyze hemoglobin gene structure and function for hummingbirds with various oxygen affinities. The activities and critical thinking discussion questions are designed to be used as part of a curriculum that addresses cellular respiration and metabolism or gene structure and function.
