What is cellular respiration?
What will be an ideal response?
Answer:
You wake up in the morning, get out of bed, and eat a nice big bowl of cereal. But how did your body get the energy to move your legs to even get out of bed? You know you need to eat to have energy, but how does your body make use of that food you eat? It all has to do with a little something called cellular respiration.
Cellular respiration is the process by which organisms turn food into a usable source of energy called adenosine triphosphate_(ATP). ATP is a molecule used to transport energy around an organism, whether that be a microscopic unicellular bacteria or a large multicellular animal like an elephant.
Muscle cells, for example, cannot directly use food to move your legs. The cells must use ATP that is made from respiration to move those legs. ATP has three phosphate groups, and when the last group is broken off, it releases energy that cells can actually use. But not all respiration is the same. Your body can actually go through two types of respiration: aerobic and anaerobic.
