Respiration is the process by which organisms convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. It's how cells get energy to function. There are two main types: Aerobic respiration* uses oxygen and is highly efficient, producing a large amount of ATP. Anaerobic respiration* does not use oxygen and produces much less ATP, often resulting in byproducts like lactic acid or ethanol. Send me the next one 📸
