If oxygen is absent in cellular respiration, then you go to anaerobic respiration. Anaerobic respiration that still uses the electron transport chain., but without oxygen.

Cellular respiration allows an organism to get energy from where?
The organisms get the reactants for cellular respiration through the process of photosynthesis. Glucose and Oxygen are produced by photosynthesis.
What process occurs in the leaves of a green plant?
The process that occurs in the leaves of a green plant is called photosynthesis. This process uses the plant's chlorophyll plus water, carbon dioxide and sunlight to produce food and also creates oxygen, as a byproduct.Read more: What_process_occurs_in_the_leaves_of_a_green_plant
Why is it not possible to stop breathing voluntarily?
Breathing is the only process where exchange of oxygen and carbon dioxide occurs. Oxygen is being delivered to the body parts where oxygen is needed, whilst removing carbon dioxide.
Why can glycolysis supply energy to cells when oxygen is not available?
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. -hazim17 sources: http://faculty.clintoncc.suny.edu/faculty/michael.gregory/files/bio%20101/bio%20101%20lectures/Cellular%20Respiration/cellular.htm This occurs via the process known as anaerobic respiration. The molecule lactic acid is used as the (temporary) electron acceptor instead of O2.
Fermentation occurs in the absence of oxygen so what is it termed?
Any respiratory reaction that takes place in the absence of oxygen is considered an anaerobic respiratory reaction. I would have to guess that that is the answer you are looking for.
When fermentation occurs what substances are available?
Oxygen
What process in cellular respiration occurs with or without oxygen?
Glycolysis
Fermentation is a process that occurs in cells and organisms that lack?
oxygen
What is the process that occurs when oxygen is no longer present in the cells?
They die out.
Which process occurs as food and oxygen combine in mitochondria?
The process by which food and oxygen combine in mitochondria is known as aerobic cellular respiration.
What is the process that occurs within the plants which requires them to take oxygen?
Cellular respiration requires oxygen as an electron receptor. This is a process which plants and animals utilize.
What process occurs at night in water systems that lowers the amount of oxygen?
respiration
Why can glycolsis supply energy to cells when oxygen is not available?
glycolisis is an anaerobic process not required O2 to function, while the Krebs Cycle and electron transport occur in the walls of the mitochondria where oxygen is used and yielded. Further, glycolisis occurs in the cytoplasm, a place of little or no oxygen.
What occurs if the oxygen flow to the body is inadequate?
If this process is inadequate, oxygen levels in the blood decrease, and the patient may need supplemental oxygen.
What is the name of the process of respiration when oxygen is available?
anaerobic respiration
What is the process that occurs as food and oxygen combine in mitochondria?
Digestion, this then creates energy for the cell
In fermentation what is the uses of DO?
Fermentation is considered an anaerobic process because oxygen is not used in the process. It is widely assumed that this occurs because oxygen is not available but this is not correct. Fermentation occurs when the substrate contains more than 1% sugar irrespective of the availability of oxygen - behaviour known as the Crabtree Effect. Yeast requires dissolved oxygen (DO) for the synthesis of lipids which are required for the integrity of the cell membrane, which in turn plays an important role in the alcohol tolerance of the cell. Yeast growth in the absence of oxygen results in weaker cells and reduced fermentation performance.
