What are the 3 main stages of cellular respiration?
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
What is the cellular respiration process?
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Which substances are needed for cellular respiration?
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
What is a direct result of aerobic respiration?
Explanation: Aerobic respiration is the reaction takes place in presence of oxygen which quite opposite to anerobic. The direct result of aerobic repiration is ATP molecules from breakdown of glucose molecules.
What is the role of molecular oxygen in the aerobic phase of cellular respiration?
Why oxygen? Oxygen is the final electron acceptor at the end of the electron transport chain of aerobic respiration. In the absence of oxygen, only a few ATP are produced from glucose. In the presence of oxygen, many more ATP are made.
What happens to oxygen in aerobic cellular respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
How would you best define the role of oxygen and carbon dioxide in aerobic cellular respiration?
What best describes the role of molecular oxygen (O2) in aerobic respiration? It accepts electrons when reacting to form water. The processes of photosynthesis and cellular respiration both involve exchanges of two gases—oxygen and carbon dioxide—with the atmosphere.
Which best describes the process of aerobic cellular respiration *?
Explanation: Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP.
Which describes the role of oxygen in photosynthesis and cellular respiration?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
Which describes the role of oxygen in photosynthesis?
Which describes the role of oxygen in photosynthesis? It is a reactant, so it is released by the plant. It is a product, so it is released by the plant. It is a reactant, so it enters the plant.
Whats is the role of oxygen in cellular respiration?
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. Oxygen combines with electrons and hydrogen ions to produce water.
What are the three end products of aerobic respiration?
End products of aerobic respiration are carbon dioxide, water and energy in the form of (38) ATP.
What is the role of oxygen in aerobic respiration microbiology?
To carry out aerobic respiration, a cell requires oxygen as the final electron acceptor. Aerobic respiration forms more ATP (a maximum of 34 ATP molecules) during oxidative phosphorylation than does anaerobic respiration (between one and 32 ATP molecules).
