And so there's nitric oxide that's sitting in the space where oxygen should be. And the red light just kicks out the nitric oxide. So now, the oxygen can come in for respiration. You get more chemical energy, which means you get more cell processes.
the main way that red light works is, inside our cells, we have things called mitochondria, the powerhouse of the cell, that produce energy through respiration. And that energy powers a lot of the biological processes inside our cells.
