Though humans, along with other vertebrate and invertebrate organisms, don't photosynthesize, we're definitely the downstream beneficiaries of the life forms that do. Phototrophic organisms at the bottom of the food chain ...
Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells' mitochondria. Through a series of reactions called the electron transport chain, electrons are passed along in a sort ...
