Yeast are a type of fungi that are used in manufacturing bread and beer.In the image below a brewer is adding hops to a fermenter, where yeast are making alcohol as a waste product from respiration.Read the excerpt from a brewery book and choose the best word to fill the blank.Alcohol builds up in the yeast cells' cytoplasm, the alcohol molecules will then leave the cell due to diffusion. This is because the concentration of alcohol molecules outside the cell is ______________ than inside the cell.the same aslowerlotshigher

Yeast breads use yeast as a leavening agent.  Yeast is a living single celled organism.  Using a chemical reaction, explain why the bread rises.

If Brewers yeast was replaced with Saccharomyces in the beer-making process, which of the following would be the most likely consequence?Group of answer choicesAlcohol and acids will be produced, but no carbon dioxideCarbon dioxide and acids will be produced, but no alcoholNo carbon dioxide or alcohol would be producedNo change, they are the same organismInstead of carbon dioxide and alcohol, sugars would be produced

Some friends are trying to make wine in their basement. They've added yeast to a sweet grape juice mixture and have allowed the yeast to grow. After several days they find that sugar levels in the grape juice have dropped, but there's no alcohol in the mixture. The most likely explanation is that ______.the mixture needs less oxygen; yeast only produce alcohol in the absence of oxygenthe mixture needs more sugar; yeast need a lot of energy before they can begin to produce alcoholthe mixture needs more oxygen; yeast need oxygen to break down sugar to produce alcoholthe mixture needs less sugar; high sugar concentrations stimulate cellular respiration, and alcohol is not a by-product of cellular respiration
