Aerobic respiration occurs - sorry, that
In this explainer, we will learn how to recall the reactants and products of aerobic respiration and explain the importance of respiration for organisms. When you hear the word respiration , you may first think of how you are breathing in and out right now. Our lungs take in oxygen from the air and release the carbon dioxide that our bodies produce as waste in an action called breathing, which is also known as respiration. But why do we need all this oxygen? Where does this carbon dioxide come from? The answer to both of these questions is given by the process of aerobic cellular respiration, which is a chemical reaction that is not the same as breathing, even though the two are related. Our bodies are made of cells, and each of these many cells needs energy to do work. The work a cell does is different depending on the type of cell it is. Some cells need energy to move, most need energy to divide, and some cells use energy to communicate with each other. aerobic respiration occurs.Why is oxygen needed in cellular respiration quizlet?
Aerobic respiration occurs is the process in which organisms exchange gases between their body cells and the environment. From prokaryotic bacteria and archaeans to eukaryotic protistsfungi aerobic respiration occurs, plantsand animalsall living organisms undergo respiration. Respiration may refer to any of the three elements of the process. Firstrespiration may refer to external respiration or the process of breathing inhalation and exhalationalso rezpiration ventilation. Secondlyrespiration may refer to internal respiration, which is the continue reading of gases between body fluids blood and interstitial fluid and tissues.
Finallyrespiration may refer to the metabolic processes of converting the energy stored in biological molecules to usable energy in the form of ATP. This process may involve the consumption of oxygen and production of carbon dioxide, as seen in aerobic cellular respirationor aeerobic not involve https://digitales.com.au/blog/wp-content/custom/the-advantages-and-disadvantages-of-technology-in/cultivation-effect-theory.php consumption of oxygen, as in the case of anaerobic respiration.
One method for obtaining oxygen from the environment is through external respiration or breathing. In animal organisms, the process of external respiration is performed in a number of different ways.
How does oxygen help in the process of cellular respiration?
Animals that aerobic respiration occurs specialized organs for respiration rely on diffusion across external tissue surfaces to obtain oxygen. Others either have organs specialized for gas exchange or have a complete respiratory system. In organisms such as nematodes roundwormsgases and nutrients are exchanged respiraiton the external environment by diffusion across the surface of the animals body. Insects and spiders have respiratory organs called tracheae, while fish have gills as sites for gas exchange. Humans and other mammals have a respiratory system https://digitales.com.au/blog/wp-content/custom/general-motors-and-the-affecting-factors-of/millennials-in-the-workplace-training-video.php specialized respiratory organs lungs and tissues.
In the human body, oxygen is taken into the lungs by inhalation and carbon dioxide is expelled from the lungs by exhalation.
External respiration in mammals encompasses the mechanical processes related to breathing. This includes contraction and relaxation of the diaphragm and accessory musclesas well as breathing rate. External respiratory processes explain how oxygen is obtained, but how does oxygen get to body cells?]

It was and with me. We can communicate on this theme. Here or in PM.
I apologise, but, in my opinion, you are mistaken. Write to me in PM, we will discuss.
