Henry's Law Constant for Oxygen Dissolving in Blood Is 0

question 67

Essay

Henry's law constant for oxygen dissolving in blood is 0.0374 mol/(L · atm) at body temperature (37°C). Calculate the ratio of the molar concentration of oxygen in the blood of a mountain climber to that of a scuba diver. Air pressure on the mountain is 0.35 atm and is 3.0 atm for the scuba diver. The mole fraction of oxygen in air is 0.209.

Definitions:

Glycogen Stores

Accumulations of glycogen within the liver and muscles, serving as a form of energy storage for the body.

Sarcoplasmic Reticulum

A network of membrane-enclosed tubules in muscle cells that stores and releases calcium ions, critical for muscle contraction.

Transverse Tubules

These are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells, facilitating the uniform contraction of the muscle.

Sarcolemma

The thin, plasma membrane that envelopes a muscle cell (fiber), playing a critical role in muscle contraction.
