Where does aerobic metabolism of glucose occur?
cytosol Glycolysis is the major pathway of glucose metabolism and occurs in the cytosol of all cells. It can occur aerobically or anaerobically depending on whether oxygen is available. This is clinically significant because oxidation of glucose under aerobic conditions results in 32 mol of ATP per mol of glucose.
What is aerobic metabolism and where does it occur?
Aerobic metabolism is part of cellular respiration and involves your cells making energy through glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation. There is detailed chemistry involved in how the body produces energy for exercise.
Which area of the cell uses anaerobic metabolism?
Glycolysis. Glycolysis is the first pathway in cellular respiration. This pathway is anaerobic and takes place in the cytoplasm of the cell. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecules.
Where does aerobic cellular occur?
The process of aerobic cellular respiration takes place mostly inside of the mitochondria, an organelle that is known as the powerhouse of the cell. Cellular respiration is a multiple step process that breaks down food into usable cellular energy.
Does anaerobic metabolism occur in the cytosol of cells?
Anaerobic metabolism occurs in the cytosol of the muscle cells. As seen in Figure 16.4. 1, a small amount of ATP is produced in the cytosol without the presence of oxygen. Anaerobic metabolism uses glucose as its only source of fuel and produces pyruvate and lactic acid.
Does anaerobic metabolism of glucose occur in red blood cells?
The red blood cell depends solely on the anaerobic conversion of glucose by the Embden-Meyerhof pathway for the generation and storage of high-energy phosphates, which is necessary for the maintenance of a number of vital functions.
What is anaerobic metabolism of glucose?
Anaerobic metabolism of glucose leads to accumulation of lactic acid, resulting in metabolic acidosis. Lactic acid reacts with bicarbonate, causing the serum bicarbonate to fall and resulting in a base deficit.
Why does aerobic respiration occur in the mitochondria?
Cellular respiration takes place (mainly) in the mitochondria because it is the cell's "powerhouse". It is where the energy (ATP) is produced in the cell, and the process of cellular respiration is the way the cells form that energy.
Where does aerobic cellular respiration occur in eukaryotic cells?
Where Does Aerobic Cellular Respiration Occur In Eukaryotic Cells? In the mitochondria. Cellular respiration takes place in eukaryotic cells as well as prokaryotic cells. In eukaryotes, most of the reactions occur in the mitochondria, it is the site of cellular respiration.
In what part of the cell does glycolysis take place?
the cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Where do the aerobic pathways take place?
Aerobic Glycolysis This pathway requires oxygen to produce ATP, because carbohydrates and fats are only burned in the presence of oxygen. This pathway occurs in the mitochondria of the cell and is used for activities requiring sustained energy production.
What is the aerobic metabolism?
Listen to pronunciation. (ayr-OH-bik meh-TA-buh-lih-zum) A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic respiration, cell respiration, and oxidative metabolism.
What is aerobic cellular metabolism?
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. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP.
Why anaerobic respiration occur in cytoplasm?
Anaerobic respiration happens in the cytoplasm where glycolysis releases energy from glucose and fermentation recycles NADH back to NAD+. The metabolic process of respiration which is the release of energy from food comes in 2 distinct flavors anaerobic respiration and aerobic respiration.
Is cytoplasm 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….Aerobic vs anaerobic respiration.
| Aerobic | Anaerobic | |

| Location | Cytoplasm (glycolysis) and mitochondria | Cytoplasm |
Where does glycolysis occur in eukaryotic cells?
mitochondrion Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Does glycolysis occur in cytoplasm or cytosol?
cytoplasm Glycolysis occurs in the cytoplasm and involves two stages which break up glucose – a 6-carbon molecule.
Why does glycolysis occur in the cytoplasm?
The most general answer is because this is where the enzymes are located that are involved in glycolysis. If the enzymes that were needed for glycolysis were not present in the cytosol … then it would not be able to take place there.
Where does glycolysis take place in the mitochondria?
cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Where does aerobic respiration take place in the mitochondria?
Mitochondria are organelles whose membranes are specialized for aerobic respiration. The matrix of the mitochondria is the site of Krebs Cycle reactions. The electron transport chain and most ATP synthesis rely on the compartments created by the inner membrane of the mitochondria.
Which process occurs in the cytoplasm?
Cytoplasm Functions Many cellular processes also occur in the cytoplasm, such as protein synthesis, the first stage of cellular respiration (known as glycolysis), mitosis, and meiosis. The cytoplasm helps to move materials, such as hormones, around the cell and also dissolves cellular waste.
Where does glycolysis in the cell take place?
cytoplasm Glycolysis occurs in the cytoplasm of the cell. Glycolysis occurs in all living organisms, aerobic as well as anaerobic. Also Check: Where Does the Krebs Cycle Take Place in the Mitochondria?
Does glycolysis take place in the nucleus?
Explanation: Glycolysis occurs in the cytosol of cells. Once finished, the two pyruvate products are transported into the mitochondria to go through the citric acid cycle, at a cost of 1 ATP per pyruvate. Neither the nucleus, nor the endoplasmic reticulum have any function in glycolysis or the citric acid cycle.
Where does anaerobic glycolysis occur?
Glycolysis occurs in the cytoplasm where one 6 carbon molecule of glucose is oxidized to generate two 3 carbon molecules of pyruvate. The fate of pyruvate depends on the presence or absence of mitochondria and oxygen in the cells.
Where does glycolysis occur cytosol or mitochondria?
cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Where is glycolysis located in the cell?
the cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Does glycolysis take place in the cytoplasm or mitochondria?
cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Does glycolysis occur in the inner membrane?
Glycolysis takes place in the cytosol, and the electron transport chain involves both the intermembrane space and the inner mitochondrial membrane. Pyruvate from glycolysis is transported into the mitochondrial matrix for the citric acid cycle.
Where glycolysis occurs in the cell?
the cytoplasm Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
Does glycolysis only occur in the mitochondria?
No, glycolysis occurs in the cytosol. Glycolysis is the process by which glucose is partially oxidised to form pyruvate, which is transported to mitochondria for further oxidation.
