Although glycolysis
Glycolysis
Glycolysis (from glycose, an older term for glucose + -lysis degradation) is the metabolic pathway that converts glucose C6H12O6, into pyruvate, CH3COCOO + H. The free energy released in this process is used to form the high-energy compounds ATP (adenosine triphosphate) and N…
How can organisms obtain energy if no oxygen is present?
When oxygen is not present, glycolysis is followed by a pathway that continues the production of ATP. This pathway plus glycolysis is called fermentation. Fermentation releases energy from food molecules by producing ATP.
What is pyruvate converted into when oxygen is not present?
In the absence of oxygen, or when oxygen demand outstrips supply, pyruvate can undergo fermentation to produce lactate. Both pyruvate and lactate can be used to regenerate glucose as well. Pyruvate can also be involved in the anabolic synthesis of fatty acids and amino acids.

Can glycolysis proceed in the absence of oxygen?
NAD+ is an oxidizing cofactor necessary to maintain the flow of glucose through glycolysis. Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. This process of breaking down glucose in the absence of oxygen is aptly named anaerobic glycolysis.
What happens when oxygen is not available?
If oxygen isn’t available, the pyruvate is converted to lactate, and no additional ATP is produced from this conversion. If oxygen is present, the pyruvates are transported into the mitochondrial matrix.
How does the body break down glucose?
These glucose molecules are a prime source of energy for your muscles, brain and red blood cells. However, your body must break down the glucose into ATP, or cellular energy, through a process called glycolysis. If oxygen is available, glycolysis is followed by ...
Which process increases ATP yield?
If oxygen is available, glycolysis is followed by two processes in the mitochondria -- the Krebs cycle and oxidative phosphorylation, respectively -- that further increase ATP yield.
Does NADH produce ATP?
Transporting NADH produced in the cytoplasm during glycolysis requires ATP, thereby reducing the net ATP yield from these NADH molecules. Additionally, FADH2 and NADH don’t always yield exactly two or three ATP, respectively, per molecule. Nevertheless, the presence of oxygen during glycolysis drastically increases the ATP production per glucose ...
