ANAEROBIC RESPIRATION is how the cells produce ATP when no oxygen is present:
Anaerobic (fermentation) vs. Aerobic Respiration
i. Without oxygen to accept electrons in the electron transport chain, most of cellular respiration stops.
ii. Fermentation enables some cells to produce ATP in the absence of oxygen.
iii. In glycolysis, glucose is oxidized to two pyruvate molecules with NAD+ being reduced to NADH.
iv. Pyruvate then accepts electrons from NADH, oxidizing it back to NAD+. The NAD+ is then available to oxidize more glucose.
v. Because the pyruvate does not enter the Krebs cycle, there is still a lot of energy which is not removed from the fuel. This is evident in yeast fermentation where the end product is alcohol - a high energy fuel.
vi. Human muscle cells switch from aerobic respiration to lactic acid fermentation to generate ATP when O2 is scarce. When O2 is absent, the ETC stops; therefore pyruvate accepts electrons, forming lactic acid. This waste product causes muscle fatigue and cramping, but it is eventually converted back to pyruvate in the liver.
vii. Under aerobic respiration, a molecule of glucose yields 36-38 ATP, but the same molecule of glucose yields only 2 ATP under anaerobic respiration.
Hope this helps. it is a section out of my Biology notes. If it doesnt, Google Anaerobic respiration and wiki will give you a good answer
What else can I help you with?
Is a process that releases energy when oxygen is insufficient?
fermentation
True or false An energy-releasing process that does not require oxygen is replication?
False. Replication is the process by which DNA is copied, and it does not release energy. An energy-releasing process that does not require oxygen is glycolysis.
The process by which cells release energy in the absence of oxygen?
The process by which cells release energy in the absence of oxygen is called anaerobic respiration. This process involves the breakdown of glucose to produce energy, with lactic acid or ethanol as byproducts. Anaerobic respiration is less efficient than aerobic respiration, which requires oxygen.
Do organelles use oxygen to release energy to glucose?
Yes, organelles, specifically the mitochondria, use oxygen to release energy from glucose through a process called cellular respiration. In this process, glucose is broken down in the presence of oxygen to produce ATP, which is the cell's main energy source.
Is oxygen needed to release energy from food?
Yes, oxygen is needed to release energy from food in a process called cellular respiration. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, which is the energy currency of cells. Without oxygen, the process of cellular respiration cannot proceed efficiently, leading to a decrease in energy production.

Is a process that releases energy when oxygen is insufficient?
fermentation
What is a process that realeases energy when oxygen is insufficient?
anaerobic respiration
What is the process that releases energy when oxygen is insufficient?
you mom, and dont cheat on your homework...
What process requires oxygen to release energy?
The process that requires oxygen to release energy is cellular respiration. In this process, cells break down glucose in the presence of oxygen to produce energy in the form of ATP (adenosine triphosphate).
What The energy-release process that does not require oxygen is?
Fermentation
What process requires the presence of oxygen to release energy?
Aerobic respiration is the process that requires the presence of oxygen to release energy. During aerobic respiration, glucose is broken down in the presence of oxygen to produce ATP, which is the energy currency of the cell.
True or false An energy-releasing process that does not require oxygen is replication?
False. Replication is the process by which DNA is copied, and it does not release energy. An energy-releasing process that does not require oxygen is glycolysis.
What is the process of using oxygen to release energy?
The process of using oxygen to release energy is called cellular respiration. In this process, glucose is broken down in the presence of oxygen to produce ATP (adenosine triphosphate), which is the energy currency of the cell. This process occurs in the mitochondria of cells and involves several complex biochemical reactions.
What is the process in which glucose and oxygen react in cells to release energy?
inhaling
The process by which cells release energy in the absence of oxygen?
The process by which cells release energy in the absence of oxygen is called anaerobic respiration. This process involves the breakdown of glucose to produce energy, with lactic acid or ethanol as byproducts. Anaerobic respiration is less efficient than aerobic respiration, which requires oxygen.
What cell is the process by which cells release energy without oxygen?
Anaerobic respiration is the process by which cells release energy without oxygen. This process occurs in the cytoplasm of cells and involves the breakdown of glucose into energy-rich molecules, such as ATP, in the absence of oxygen. Anaerobic respiration is less efficient than aerobic respiration but allows cells to continue producing energy when oxygen is limited.
