Aerobic organisms obtain most of their energy from Respiration, which is defined as the oxidation of organic fuels by molecular oxygen; oxygen thus serves as the final electron acceptor in aerobic respiration.
Mitochondria is primarily where these processes take place.
What else can I help you with?
Cellular respiration cannot occur without the presence of what molecule?
Oxygen. Oxygen is necessary for cellular respiration to occur because it serves as the final electron acceptor in the electron transport chain, allowing for the production of ATP.
Where do the final steps in aerobic cellular respiration occur?
The final steps of aerobic cellular respiration occur in the mitochondria, specifically in the electron transport chain and oxidative phosphorylation. Here, most of the ATP is produced through the electron transport chain by using the energy carried by electrons from previous stages of respiration.
Which substance is needed for areobic cellular respiration to occur?
Oxygen is needed for aerobic cellular respiration to occur. It serves as the final electron acceptor in the electron transport chain, allowing for the production of ATP in the presence of glucose and other nutrients.
What element must be present for both steps of cellular respiration to occur?
Oxygen is the element that must be present for both steps of cellular respiration to occur. It acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP through oxidative phosphorylation.
True OR false type of cellular respiration that requires oxygen to occur?
It is TRUE that AEROBIC respiration requires oxygen to occur. It is FALSE that ANAEROBIC respiration requires oxygen to occur. It is FALSE that cells are DEPENDENT on AEROBIC respiration.
Oxygen is what in cellular respiration?
Oxygen is the final electron acceptor in the electron transport chain during cellular respiration. It is essential for the production of ATP, the energy currency of the cell, through a series of reactions that ultimately result in the formation of water.
What is the cellular respiration takes place in the cell is?
The first step, glycolysis, occurs in the cytoplasm. The Krebs cycle and the electron transport chain occur in the mitochondria.
Where is the last three stages of cellular respiration?
The last three stages of cellular respiration occur in the mitochondria. They are the citric acid cycle (Krebs cycle), electron transport chain, and oxidative phosphorylation. These stages involve the production of ATP, the cell's main source of energy.
What is needed for cellular respiration to occur in cells reactants?
Cellular respiration requires oxygen and glucose as reactants to occur in cells. Oxygen is needed as the final electron acceptor in the electron transport chain, while glucose is broken down in a series of metabolic pathways to produce ATP, the cell's energy currency.
What does cellular respiration occurs in the presence of?
Generally it will occur in the presence of oxygen, which is aerobic respiration, but there are other times where no oxygen will be present and cellular respiration will occur anaerobically (fermentation). Aerobic respiration is more beneficial because you produce more ATP than anaerobically.
Which part of cellular respiration will provide the squirrel with most of the energy it needs to escape?
the electron transport chain
Where in the cell do the two stages of respiration occur?
The two stages of respiration, glycolysis and cellular respiration (Krebs cycle and electron transport chain), occur in different parts of the cell. Glycolysis takes place in the cytoplasm, while the Krebs cycle and electron transport chain occur in the mitochondria.
