Well, you breathe in...with your mouth or nose. Just suck in some air. ;)
Animals need oxygen to carry out life processes. Plants need carbon dioxide. Some animals and plants can use either if they need to.
The element we need to breathe is oxygen. It is essential for cellular respiration, where our cells convert oxygen into energy to carry out their functions.
Yes, they do use oxygen to carry out cellular respiration.
The body needs glucose and oxygen to carry out cellular respiration. Glucose is the primary source of energy, and oxygen is needed as the final electron acceptor in the electron transport chain to produce ATP.
You need oxygen from the air, aswell as glucose, in order to carry out respiration which is a chemical process producing energy.
To carry out respiration plants need the same things as you do! To carry out aerobic respiration they need a food source eg glucose, and oxygen: glucose + oxygen ----> water + carbon dioxide + ENERGY To carry out anaerobic respiration they ony need a source of food: glucose ----> carbon dioxide + ethanol (alcohol) + ENERGY It is important to realise that plants Cary out respiration all of the time, just as your cells do. Also, remember that respiration is the release of energy from food, not breathing. See http://www.bbc.co.UK/schools/gcsebitesize/biology/greenplantsasorganisms/0photosynthesisrev6.shtml
Oxygen is the gas that is required for respiration.
Yes, plants carry out aerobic cellular respiration to get energy from food just like we do. So when people say that oxygen is a waste product of photosynthesis they are incorrect. Plants need oxygen just like other organisms for aerobic respiration. It's just fortunate for the rest of the life forms on Earth that plants produce more oxygen than they need.
Cellular respiration need oxygen. This oxygen is supplied by external respiration
Yes, white blood cells need oxygen to function properly. Oxygen is essential for all cells in the body, including white blood cells, to carry out various metabolic processes and support immune functions.
In order for any organism to continue to live and reproduce it needs to carry out the biological function of cellular respiration. So oxygen, glucose or sugar are definitely needed. In some cases though bacteria does not need oxygen if it can carry out anaerobic respiration.
When oxygen runs out, the muscles and other cells need to obtain energy from oxygen and nutrients. Anaerobic respiration (respiration without oxygen) fills this need.
