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 the inhibition of complex I of the electron transport chain by viral proteins, resulting in a reduced flow of electrons. 1. How would this reduced flow of electrons impact ATP synthesis and oxygen consumption? 2. Why might this lead to fatigue (exhaustion) in the individual? Please be specific and explain clearly.

Extra Credit – Answer either question as completely as possible 1.  Explain how solutes such as salt and sugar preserve and extend the shelf life of foods.
