1. How is the last step of the oxygen transport cascade altered
acutely? Chronically? Clearly explain your answer.

2. The aquatic Lake Titicaca frog,Telmatobius culeus, is endemic
to high Andean lakes (3812 meters above sea level) and has greatly
reduced lungs, but elaborated skinfolds which are well perfused. It
has one of the lowest recorded metabolic rates for amphibians at
14.1 μL gL g-1h-1. It also has the smallest reported erythrocyte
volume (394 μL g3) for any amphibian, and a reduced O2 carrying
capacity of its blood at 11.7 vol %. Based on your knowledge of the
oxygen carrying capacity of blood, what might explain the low
carrying capacity in T. culeus? When these frogs are submerged at
the bottom of these alpine lakes, they occasionally bob by pushing
off the lake bottom with their hind legs and floating back down
again. What might be the function of this bobbing behavior? How
would you quantify this bobbing function?
