Is respiration and cellular respiration the same?
Is respiration and cellular respiration the same?
Breathing is often referred to as respiration. When you breathe, you take oxygen into your lungs as you inhale, and you release carbon dioxide and water vapor as you exhale. Inside all the cells of your body, a different kind of respiration takes place. This kind of respiration is called cellular respiration.
What is cellular respiration answer?
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
What is cellular respiration quizlet?
cellular respiration. the process in which cells make ATP by breaking down organic compounds. photosynthesis. the process in which autotrophs convert light energy into chemical energy.
Is cellular respiration aerobic or anaerobic?
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.
What happens during anaerobic cellular respiration?
What happens during anaerobic respiration? Glucose is not broken down completely, produces lactic acid,releases small amount of energy for cells ( not as efficient as aerobic respiration,as glucose molecules aren’t broken down completely.
What is the fate of glucose in anaerobic respiration?
The fate of glucose in anaerobic respiration in yeast is ethanol and carbon dioxide with release of energy. The fate of glucose in aerobic respiration in humans is water and carbon dioxide with release of energy.
Why is cellular respiration more efficient when oxygen is present in cells?
Though cellular respiration can occur anaerobically without oxygen, the process is much more efficient under aerobic conditions, in the presence of oxygen. And what exactly is the role of oxygen? Oxygen is the final electron acceptor of the electron transport chain in the final step of cellular respiration.
What is the advantage of cellular respiration?
A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can just split glucose into two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.
What does glucose turn into during cellular respiration?
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
How does cellular respiration create water?
The electron transport chain is the third and final step of cellular respiration. Toward the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen that the cell has consumed and reacts with it to form water. In this way, water is created as a byproduct of the metabolism reaction.
