Yes. Yeast respire anaerobically by ethanol fermentation. This is different from the lactic acid fermentation in humans in that it produces copious amounts of ethanol and carbon dioxide rather than lactic acid. This production of ethanol and carbon dioxide makes yeast the organism of choice for the brewing of alcoholic drinks and bread-making.
I was just looking up the same thing because I am doing my GCSE in a couple of days...it is the same as aerobic respiration in humans..(the only difference is yeast can also respire anerobically if there is no oxygen available, although this produces less engergy) glucose + oxygen --> water + carbon dioxide + energy (32 ATP) - (whereas anerobically yeast would only have made 2 ATP) Hope that helps!
Aerobic respiration requires oxygen to produce energy, while anaerobic respiration does not require oxygen. Aerobic respiration yields more energy (ATP) compared to anaerobic respiration, but anaerobic respiration is less efficient and produces lactic acid or ethanol as byproducts.
Yeast will ferment in anaerobic conditions (without oxygen) to produce energy in the form of ethanol and carbon dioxide. In aerobic conditions (with oxygen), yeast will respire using oxygen to generate energy in the form of ATP.
In yeast, respiration involves the breakdown of glucose to produce energy in the form of ATP. This process occurs in the mitochondria of yeast cells and involves a series of enzymatic reactions known as the citric acid cycle and oxidative phosphorylation. The end products of respiration in yeast are carbon dioxide, water, and ATP.
Aerobic respiration requires oxygen; anaerobic respiration does not use oxygen.

No, yeast does not produce carbon dioxide (CO2) during aerobic respiration. In aerobic respiration, yeast uses oxygen to completely break down glucose into carbon dioxide and water, resulting in CO2 as a byproduct. However, the process is more efficient than anaerobic respiration, where yeast ferments sugar and produces both ethanol and CO2. So, while CO2 is produced in aerobic conditions, it is not the primary energy-generating pathway for yeast.
Yes, yeast is capable of producing carbon dioxide through aerobic respiration when oxygen is present. This process involves the breakdown of glucose to produce energy, carbon dioxide, and water.
Between 65-70%
Aerobic (used to make bread) and anaerobic (used to make alcohol).
Yeast cells switch from aerobic to anaerobic respiration during ethanol production primarily due to the depletion of oxygen in their environment. In the absence of oxygen, yeast undergo fermentation, converting sugars into ethanol and carbon dioxide as byproducts. This anaerobic process allows yeast to continue generating ATP for energy, albeit less efficiently than aerobic respiration. The production of ethanol also helps inhibit the growth of competing microorganisms.
Yeast is most likely to use anaerobic respiration. This is because yeast is a single-celled microorganism that can switch to anaerobic respiration when oxygen is not available. Birds, moss, and trees are larger, multicellular organisms that largely rely on aerobic respiration for energy production.
Yeast respiration requires sugar (such as glucose) as a substrate, oxygen for aerobic respiration, and yeast cells to carry out the process. This process results in the production of carbon dioxide, water, and energy in the form of ATP.
Glucose. It can also use sucrose and maltose, but much less than glucose.

The rate of respiration decreases when oil is added to yeast because oil creates a barrier that inhibits oxygen diffusion into the yeast cells. Oxygen is essential for aerobic respiration, and with limited access, yeast must rely on anaerobic processes, which are less efficient in energy production. Additionally, the oil can disrupt the yeast's cellular membranes, affecting metabolic functions further. As a result, overall respiration rates decline.
Aerobic respiration requires oxygen to produce energy, while anaerobic respiration does not require oxygen. Aerobic respiration yields more energy (ATP) compared to anaerobic respiration, but anaerobic respiration is less efficient and produces lactic acid or ethanol as byproducts.
