Answer

The efficiency of the synthesis of ATP is reduced in the presence of DNP. Therefore, cells need more fuel, glucose, and oxygen to meet their energy needs. Respiration increases to meet the high oxygen demand. The excess heat produced during the passive movement of protons across the membrane manifests into a fever. Thus, reduced ATP levels can cause individual cells to die, thereby impairing the metabolic activities of the individual and eventually leading to the death of the individual.

Work Step by Step

Passive proton movement is seen in brown adipose tissue. It generates heat instead of ATP production. Similarly, DNP can also generate heat, resulting in the symptoms. The accumulation of systemic cell death resulting from the lack of ATP leads to complications like organ failure, which mostly result in death.
