Both aerobic and anaerobic respiration take place. They can do either. They are known as facultative anaerobes

∙ 14y agoI think yeast which are single celled organism and breaths anearobically and during this process yield alcohol. I am anyway not clear about anearobic breathing.

What determines whether yeast ferments or respires?
Yeast is a great example of Cellular Respiration. In a normal (Anaerobic) reaction, yeast breaks down sugar to release carbon dioxide and ethyl alcohol. When oxygen is added to the sugar and yeast, Aerobic respiration occurs. This releases more energy and less carbon dioxide than Anaerobic respiration. Of course, the reactions have to occur very close to 40 degrees Celsius or the yeast will die. If temperatures are too low, the reaction will not occur.
Is fermentation a form of respiration or photosynthesis?
No; fermentation is an alternative metabolic pathway to respiration, not photosynthesis. Both processes (photosynthesis and respiration) have alternative pathways depending on conditions.
Where is photosynthesis and cellular respiration take place?
Photosynthesis occurs in the chloroplast. During photosynthesis, carbon dioxide, water, and light energy is turned into glucose and oxygen. Cellular respiration occurs in the mitochondria. During cellular respiration, glucose and oxygen and turned into carbon dioxide, water, and energy. As you can see, the are both really a big cycle.
Cellular respiration occurs in what cells?
Anaerobic respiration occurs in some bacteria and fungi as well as yeasts.
Where does the carbon dioxide come from in cellular respiration?
The breakdown of glucose to carbon dioxide and water occurs during glycolysis and aerobic respiration in cellular respiration. The carbon dioxide is a waste product.
What occurs during the first stage of respiration?
Glycolysis occurs in the cytoplasm during the first stage of respiration.
When do green plants carry on respiration?
both photosynthesis and cellular respiration occurs during the day, however, during the night when there is no sunlight only cellular respiration occurs.
What is alcoholic fermentation and where does it occur?
Yeast turns sugar into alcohol and carbon dioxide to produce energy (anaerobic respiration), it occurs just about wherever there is yeast and sugar.
Reduction of oxygen which forms water occurs during?
The reduction of oxygen that forms water occurs during respiration. It occurs when oxygen and hydrogen mix to form what is called metabolic water.
What are facts about ethanol?
during anaerobic respiration in yeast and bacteria ethanot is the by product
Synthesis of ATP by chemiosmotic mechanism occurs during?
This process occurs during the light reactions of photosynthesis.

What chemical substance do yeast consume?
Yeast uses sugar in respiration.Glucose is the primary substrate.This is oxidized during respiration
Where respiration occurs?
Respiration occurs in the cells.
When Cells use oxygen to release energy during?
Cells don't do fermentation, the yeast does. Cells don't do fermentation, the yeast does.
How yeast excrete?
Yeast excrete CO2 after they undergo respiration.
Synthesis of ATP by the chemiosmotic mechanism occurs during?
both photosynthesis and respiration
