Which energy source would you expect to be depleted first during continuous contractions caused by the tetanus toxin?

A potentially serious complication of tetanus is the destruction of the muscle fibers themselves, a condition known as rhabdomyolysis. The breakdown of muscle fibers releases myoglobin into the blood, which can put a strain on the kidneys and lead to a decline in their function.

Joe's physician notes that his kidney function has declined. She suspects that this may be a result of this muscle fiber breakdown, because myoglobin was detected in Joe's urine. She initiates immediate therapy for the kidney dysfunction and orders additional tests to look at the level of myoglobin in his blood. This is a setback for Joe's recovery, and makes his prognosis more serious. Fortunately, his physician has discovered this complication early and has taken measures to protect his kidneys from the circulating myoglobin.

Which energy source would you expect to be depleted first during continuous contractions caused by the tetanus toxin?

a. Myoglobin b. ATP generated by oxidative or aerobic catabolism c. ATP generated by glycolytic or anaerobic catabolism d. Creatine phosphate

Explanation / Answer

Depleted first during continuous contractions caused by the tetanus toxin is myoglobin because in aerobic respiration using oxygen from myoglobin then phasphogen has activated.
