MAKE CONNECTIONS Describe similarities in the countercurrent exchange that facilitates respiration in fish and thermoregulation in geese (see Figure 32.15).

Recall from your BI110 class that metabolically active tissues produce CO2 as a by-product of cellular respiration. Those metabolically active tissues require the O2 that is brought by hemoglobin for the same process (cellular respiration). Explain why the effect of pH on hemoglobin’s affinity for oxygen is consistent with delivering it to actively metabolizing tissues. (Hint: think about what effect the presence of CO2 has on the tissues…)
. MAKE CONNECTIONS Explain how the change of asingle amino acid in hemoglobin leads to the aggregation of hemoglobin into long fibers. (Review Figures 5.14,5.18, and 5.19.)
Describe how oxygen is used in aerobic respiration in the ETS. What are the metabolic sources of carbon dioxide and water?
