Most of the time, Ultraviolet radiation will kill or badly hurt most yeasts. As there are so many different kind of yeasts, each different kind of yeast will have a different reaction to this kind of light. There are also certain mutations that may cause yeast to be ultraviolet light sensitive or resistant.

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 can i explain the process of fermentation?
Fermentation is a process that converts sugar to acids, gases or alcohol. In yeast the fermentation process is carried our in beers, wines and other alcohol.
Name 3 yeast behaviors based on modern concepts of microbial metabolism?
Three concepts of yeast behaviors are fermentation, aerobic or anaerobic respiration, and nitrification. Fermentation converts sugar to acids. Nitrification is the conversion of ammonia to nitrites.
What is achoholic fermintaition?
Alcohol is produced as a byproduct of live yeast. The yeast digests the sugar from the mash and excretes alcohol. The process is called 'Fermentation'
In which of these does alcoholic fermentation occur?
Alcohol fermentation is done by yeast and some kinds of bacteria. These microorganisms convert sugars in ethyl alcohol and carbon dioxide. Alcoholic fermentation begins after glucose enters the cell. The glucose is broken down into pyruvic acid. This pyruvic acid is then converted to CO2, ethanol, and energy for the cell. Humans have long taken advantage of this process in making bread, beer, and wine. In these three product the same microorganism is used: the common yeast or Saccharomyces Cerevisae.http://www.tempeh.info/fermentation/alcohol-fermentation.php
What is it called when yeast respire anaerobically?
fermentation
What type of fermentation is carried out by yeast?
Alcoholic fermentation
Which pathogen causes fermentation?
Yeast is a common microorganism that causes fermentation. Specifically, species of Saccharomyces yeast are often used in fermentation processes, such as brewing beer and making bread.
Is yeast sensitive to light?
Yes, yeast is sensitive to light. Exposure to light, especially ultraviolet (UV) light, can damage yeast cells and affect their growth and metabolic activities. Storing yeast in a cool, dark place is recommended to maintain its viability and effectiveness.
Why do we use sugar in yeast?
the sugar has power over fermentation. fermentation can not continue without sugar or yeast
How do the products of fermentation in animals differ from yeast?
In animals, fermentation produces lactate or lactic acid as a byproduct, while in yeast, fermentation produces ethanol and carbon dioxide. Lactic acid fermentation does not produce energy as efficiently as ethanol fermentation, which is why animals primarily rely on it during high-intensity exercise when oxygen is limited. Fermentation in animals occurs in muscle cells, while yeast fermentation takes place in yeast cells.
What types of fermentation occurs in bacteria and yeast?
Alcohol fermentation.
What is the raw materials of alcohol fermentation?
The raw materials for alcohol fermentation are generally sugar (such as glucose or sucrose) and yeast. Yeast metabolizes the sugar through the process of fermentation, converting it into alcohol and carbon dioxide. Water is also required for the fermentation process.
What is the product of fermentation in yeast?
alcohol
Yeast cells carry out fermentation when they are supplied with what type of molecule?
Yeast cells carry out fermentation when they are supplied with glucose molecule.
Yeast respires anaerobically. what is the name of this process in yeast?
Fermentation is the process by which yeast respires anaerobically to produce energy in the form of ATP and fermentation byproducts such as ethanol and carbon dioxide.
What can you put yeast in?
You can put yeast in bread dough to help it rise, in beer or wine to aid in fermentation, and in pizza dough to create a light and airy crust.
