Optional up to 2 points of extra credit: SARS-CoV-2, the virus that causes COVID, results in long COVID in a percentage of individuals. Estimates of this number vary for a number of reasons, but many studies have suggested 10-20% of those infected go on to develop long term symptoms characteristic of long COVID. One of these symptoms is fatigue (exhaustion). Although research is ongoing, the virus is thought to impact mitochondria in a number of ways. One such way is via damage to the mitochondrial complexes, leading to increased production of reactive oxygen species (ROS), resulting in oxidative stress to the mitochondria that can make the inner mitochondrial membrane “leaky” (more permeable), allowing protons to flow across the membrane down their gradient. 1. How would this membrane “leakiness” (increased permeability) impact ATP synthesis, and why? 2. How might this lead to fatigue (exhaustion) in the individual? Please be specific and explain clearly.
