When a tiger is running across a field would happen if the hydrogen on pumps in the Tigers mitochondria stopped functioning?

If the hydrogen pumps in a tiger's mitochondria stopped functioning, it would severely impair the animal's ability to produce ATP, the energy currency of cells. This disruption would lead to a lack of energy for muscle contractions, resulting in fatigue and an inability to sustain running. Consequently, the tiger would struggle to maintain its speed and agility, significantly impacting its ability to hunt and survive in the wild.
