What happens after glycolosis if there is no oxygen available?
If there is no oxygen available after glycolysis, anaerobic respiration occurs. This process involves the conversion of pyruvate into lactic acid (in animals) or ethanol (in yeast and some bacteria) to regenerate NAD+ and continue ATP production. Anaerobic respiration is less efficient than aerobic respiration in terms of ATP production.
What is produced in the absence of oxygen during glycolysis?
In the absence of oxygen during glycolysis, pyruvate is converted into lactate through a process called fermentation. This allows glycolysis to continue generating ATP in the absence of oxygen by regenerating NAD+ from NADH, which is needed for glycolysis to proceed.
Which step in the process of glycolysis requires the presence of oxygen?
None of the steps in glycolysis require the presence of oxygen. Glycolysis is the process of breaking down glucose to produce energy, and it occurs in the cytoplasm of cells, independent of oxygen availability.
What is glycolysis when oxygen is available?
Glycolysis, in the presence of oxygen, is the first stage of cellular respiration where glucose is broken down into pyruvate. This process occurs in the cytoplasm of the cell and produces a small amount of ATP and NADH. The pyruvate then enters the citric acid cycle to further extract energy from it.
What does it mean to say that glycolysis is an aerobic process?
Cellular respiration sometimes is referred to as aerobic respiration, meaning that it occurs in the presence of oxygen, and is not an anaerobic process. Glycolysis is one of the processes in cellular respiration. In the final steps of glycolysis, two hydrogen atoms are removed from each three-carbon compound by bonding to free-floating oxygen atoms in the cytoplasm to form water.
What happens when oxygen is present after glycolysis?
fermentation
What happens if oxygen is not persent after glycolysis?
the entire process of cellular respiration stops
Does glycolysis happen with or without oxygen?
Many types of bacteria can live in Anaerobic conditions, I.e they don't need oxygen to live, as they create energy using anaerobic respiration.
Does glycolysis stop when oxygen becomes unavailable to the cell?
Actually that's when the glycolysis occurs at a greater rate. Glycolysis is anaerobic, meaning it doesn't require oxygen. Without the presence of oxygen, glycolysis is undertaken to produce small amounts of ATP. It can also make lactic acid which can build up and become toxic to the body.
What happens to pyruvate molecules formed glycolysis in the absence of oxygen?
they will enter the Krebs cycle
Oxidative respiration follows glycolysis when is available?

Is oxygen necessary for glycolysis?
No - glycolysis is anaerobic (it does occur in the presence of oxygen).
Why can glycolysis supply energy to cells when oxygen is not avalable?
Glycolysis can occur without oxygen. Although glycolysis does not require oxygen, it does require NAD+. Cells without oxygen available need to regenerate NAD+ from NADH so that in the absence of oxygen, at least some ATP can be made by glycolysis.
What happens when oxygen is present and includes glycolysis Krebs cycle and election transport?
Cellular Respiration
If a cell has no oxygen what stages of aerobic cellular respiration can still run?
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.
What happens when no oxygen is present ffor respiration?
If no oxygen is available, most living things will die.
When oxygen is available a cell will begin what happens after glycolysis?
After glycolysis, in the presence of oxygen, the cell will undergo the Krebs cycle (also known as the citric acid cycle) and oxidative phosphorylation (electron transport chain) to produce more ATP. This process occurs in the mitochondria and is the primary way cells generate energy in the form of ATP from glucose.
