Oxygen
Glycolysis occurs in the cytoplasm of the cell. It is the first stage of cellular respiration and does not require oxygen to produce energy in the form of ATP.
It is false that if oxygen is present in a cell, pyruvic acid in glycolysis enters the chloroplasts. The pyruvic acid enters the mitochondria if oxygen is present in a cell.
In the fermentation of one molecule of glucose, no molecular oxygen is required. Fermentation is an anaerobic process that does not involve oxygen and is used by some organisms to generate energy from glucose in the absence of oxygen.
A multicellular organism can not rely on glycolysis alone for energy because glycolysis is just one step in respiration. Glycolysis alone does not produce the amount of oxygen that a multicellular organism needs.
Oxygen
In the absence of oxygen after glycolysis, muscle cells will produce lactic acid through the process of fermentation. This allows the cells to regenerate NAD+ needed for glycolysis to continue in the absence of oxygen.
Glycolysis is a process in eukaryotic cells that will proceed normally whether oxygen is present or absent. Glycolysis breaks down glucose to produce ATP, the cell's energy currency, and occurs in the cytoplasm. It does not require oxygen and is the first step in both aerobic and anaerobic respiration pathways.
Glycolysis occurs in the cytoplasm of the cell. It is the first stage of cellular respiration and does not require oxygen to produce energy in the form of ATP.
If there is no oxygen available, only glycolysis can still run in anaerobic conditions. The Krebs cycle and electron transport chain, both of which require oxygen, cannot proceed. Glycolysis produces ATP by breaking down glucose into pyruvate without the need for oxygen.
It is false that if oxygen is present in a cell, pyruvic acid in glycolysis enters the chloroplasts. The pyruvic acid enters the mitochondria if oxygen is present in a cell.
In the fermentation of one molecule of glucose, no molecular oxygen is required. Fermentation is an anaerobic process that does not involve oxygen and is used by some organisms to generate energy from glucose in the absence of oxygen.
Glycolysis does not directly depend on oxygen because it is an anaerobic process that occurs in the cytoplasm of a cell. However, the final products of glycolysis, pyruvate, are further metabolized in the presence of oxygen through aerobic respiration to generate more energy. Oxygen is necessary for the complete breakdown of pyruvate in the citric acid cycle and oxidative phosphorylation to efficiently produce ATP.
Aerobic glycolysis occurs in the cytoplasm of cells. It is the process by which glucose is broken down to produce energy in the form of ATP in the presence of oxygen.
Glycolysis is the only step in cell respiration that is not oxygen-dependent. It takes place in the cytoplasm and does not require oxygen to convert glucose into pyruvate, generating a small amount of ATP in the process.
Glycolysis occurs in the cytosol of the cell. It is the metabolic pathway that breaks down glucose to produce energy in the form of ATP.
A multicellular organism can not rely on glycolysis alone for energy because glycolysis is just one step in respiration. Glycolysis alone does not produce the amount of oxygen that a multicellular organism needs.
