Enzyme kinetic analysis reveals a dynamic relationship between enzymes and their substrates. Overall enzyme activity can be controlled by both protein expression and various cellular regulatory systems. Interestingly, the availability and concentrations of intracellular substrates can constantly change, depending on conditions and cell types. Here, we review previously reported enzyme kinetic parameters of cellular and viral DNA and RNA polymerases with respect to cellular levels of their nucleotide substrates. This broad perspective expo

Mitochondria are integral to maintaining cellular homeostasis. Optimum mitochondrial function is critical during embryonic development, as they play a key role in early signaling cascades and epigenetic programming, in addition to sustaining an adequate energy production. Mitochondria are sensitive targets of environmental toxins, potentially even at levels considered safe under current regulatory limits. Most mitochondrial analyses have focused only on chemical exposure effects in vitro or in isolated mitochondria. However, comparativel
