Hi, I’m Dan Weisenberger, and this is, “What Are the Products of Photosynthesis and Respiration, and How Are They Essential for Life?” Well, photosynthesis, shown here, is a very complex and involved series of chemical reactions that ultimately converts light energy, in the presence of water and carbon dioxide, into sugar and oxygen. Respiration occurs primarily in the mitochondria of cells and is involved in the oxidated phosphorylation pathway, in which sugars are converted into large amounts of ATP, oxygen is mainly converted into water, and carbon dioxide is released. So, with these products in mind, let’s look at how they’re needed for life. Sugar is a universal energy source for the plants that synthesize it, and the animals that consume that. Oxygen being released into the air is essential for animals to breathe in for their life. ATP is another universal energy source that is important for the cell to function, grow, and develop. And, finally, the output of carbon dioxide into the atmosphere serves as a substrate for photosynthesis, and this cycle enables life for plants and animals.
