Skip to 0 minutes and 4 secondsSo we all know that we need oxygen for respiration. And many of us think of respiration just being the process of breathing. Actually, respiration provides us with all the energy that we need for the biochemical processes that go on in our body. During respiration, glucose reacts with oxygen. And that produces carbon dioxide, and water, and importantly, energy.
Skip to 0 minutes and 38 secondsSo this energy is stored in a molecule called ATP. And ATP is Adenosine Triphosphate. And when adenosine triphosphate, is converted into ADP, Adenosine Diphosphate, then energy is released. And it's this energy that is used by our body in all those biochemical processes. Now in terms of our mission to Mars, obviously, respiration is going to be crucially important. But you can say that it produces carbon dioxide and water. Water is going to be a very precious resource. So we'll want to capture this water and recycle it. However, the carbon dioxide is going to be harmful to our colony. So we'll need to capture the carbon dioxide and try and reextract the oxygen from it.
Watch Tina explain how respiration provides us with the all the energy we need for the biochemical processes that go on in our body.
