Functions of normal mitochondria vs. effects on mitochondria in the presence of SARS-CoV-2. Normal mitochondria have a balance on fission and fusion, produce ROS only in quantities necessary, have balanced iron storage, and use mitophagy to upkeep functional mitochondria and protect the cell against damage. In the presence of SARS-CoV-2, mitochondria may have increased fusion (Shi et al., ; Zhang et al., ), an excess of ROS production (Kuka et al., ; Kang et al., ), too much iron in storage (Saleh et al., ), and impaired mitophagy that leads to platelet apoptosis (Lee et al., ; Tang et al., ). SARS-CoV-2 affects mitochondria may also serve as a source of double-membraned vesicles for the virus to travel in (Singh et al., ).
