Some people suffer from a genetic disease that causes the protein responsible for transporting fatty acylcarnitine (acyltransferase II) to malfunction. Symptoms of this disease include muscle weakness and fatigue. These effects are often more severe after fasting (i.e. not eating). Using biochemistry, explain why these people may have difficult generating energy for their cells.
Excellent answers will address the metabolic pathway affected in this disease, how the affected protein works in this pathway and how this pathway influences energy generation in a cell.
