ANATOMY

Detailed explanation-1: -Most living organisms, including plants and animals, require oxygen for life. Organisms need oxygen for cellular respiration, in which energy is released from glucose. Energy is needed by the organism for growth, mobility, and reproduction.

Detailed explanation-2: -Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.

Detailed explanation-3: -Oxygen is required in the cellular respiration in the electron transporter chain. It serves as the final electron acceptor of the electron transport chain facilitating the movement of electrons down the chain hence producing the ATP or adenosine triphosphate.

Detailed explanation-4: -What is the purpose of cellular respiration? Cellular respiration is used to generate usable ATP energy in order to support many other reactions in the body. ATP is particularly important for energetically unfavorable reactions that would otherwise not occur without an energy input.

Detailed explanation-5: -Answer and Explanation: Plants create energy through photosynthesis turns oxygen, water, and sunlight into oxygen and energy. Animals create energy by breaking down carbohydrates and oxygen to turn it into carbon dioxide and water.
