Question

8. Theoretically, the consumption of glucose by a skeletal muscle could be determined by measuring the concentration of glucose in the blood sampled entering and leaving the muscle. If the circulating blood is deoxygenated, the muscle consumes glucose at a steady rate. When oxygen is added to the blood, the rate of glucose consumption drops dramatically, and then continues at the new, lower rate. Why? (4 points)

Step 1

When the circulating blood is deoxygenated, it means that there is a lower concentration of oxygen in the blood. This indicates that the muscle is not receiving enough oxygen for its metabolic needs. Show more…
