What does cellular respiration allows an organism to get energy from?
Cellular respiration provides energy (in the form of ATP) for the cell to perform its numerous metabolic reactions efficiently. Cellular respiration primarily involves the mitochondria, while the first stage occurs in the cytosol. Glucose is utilised as a substrate for cellular respiration, which should be distinguished from external respiration (aka breathing).
Living things use energy in order to live, so we are constantly using converting ATP to ADP in order to get that energy. Cellular respiration replenishes the ATP by converting ADP back into ATP, which living things use for energy. Without cellular respiration an organism would die from lack of ATP, and therefore a lack of energy.
Why would a multi-cellular organism prefer to use cellular respiration rather than fermentation as a method to produce energy?
They would prefer cellular respiration because cellular respiration is the metabolic processes whereby certain organisms obtain energy from organic molecules; processes that take place in the cells and tissues during which energy is released and carbon dioxide is produced and absorbed by the blood to be transported to the lungs (answer from google)
What is the process by which an organism obtains the energy it needs by releasing the chemical energy in nutrients?
Photosynthesis is crucial to the way earth allows organisms to live because the plants that undergo photosynthesis release oxygen into the air which allows tree's to grow and cellular respiration to occur. They also gain ATP or energy from the sun's light which provides secondary consumers or herbivores energy when preyed upon. Cellular respiration is important and vital to earth simply because this is the way all organisms breathe. Cellular respiration goes through 3 steps…
In case of the cellular respiration, glucose molecule is burned out to carbon bi oxide and water. In chemical burning you get heat released suddenly. In case of biological oxidation, the energy is released in step wise fashion. Most of the energy is trapped in ATP molecule. Some of the energy is released as heat.
Cellular respiration is not the same as breathing. Respiration is just breathing in oxygen and breathing out carbon dioxide, but cellular respiration is a chemical reaction that uses oxygen and glucose which gives the products carbon dioxide, water, and energy. Cellular respiration is a process that takes place in all cells, in which glucose is added to oxygen, and through a chemical reaction, yields water and energy. The formula for this is C6H12O6 + 6O2…
No, this is not true, all organisms undergo cellular respiration. Only the green (chlorophyll containing) cells of a plant can perform photosynthesis to build sugars using the energy from sunlight, these cells and other cells in the plant (that can't perform photosynthesis) break down those sugars through respiration to get the energy they need (in the form of ATP) to perform other cellular functions. All photosynthesis is, is a way to capture the energy of…
Cellular respiration cannot happen without oxygen. If there is no oxygen, only the glycolysis step will occur, and no ATP (energy) will be made, resulting in death. That is why humans die out in space; no oxygen is capable of being found, and cellular respiraiton cannot occur. An organism lacking oxygen for cellular respiration would die, because oxygen is needed to make energy to live.
