Excess sugar produces a very negative water potential and this causes water to move out of the yeast cells into the sugar solution (by osmosis)- the cells become dehydrated, they do not have enough water for cell growth (yeast cells are usually 90% water).

What effect does yeast have on sugar solution?

when a yeast cell is put in a hypertonic solution, water moves out of the cell down its osmotic gradient to the outside of the cell by osmosis as a result the cell shrinks

What happens if you put coke and yeast together?

When coke and yeast are combined, the yeast will likely start consuming the sugars present in the coke through the process of fermentation. This can result in the production of carbon dioxide gas, alcohol, and possibly other byproducts. However, the presence of preservatives in commercial coke may inhibit the growth and activity of yeast.


What happens when dry yeast and sugar and flour is mixed and put into a bowl with a paper towel covering it?

Nothing. The yeast needs to be activated. Sensible answer: If the mixture is kept perfectly dry, not a lot. Yeasts need moisture and a slightly acidic pH to activate. The yeast works by digesting the sugars and starches in the mixture to make more more yeast (by reproduction) and carbon dioxide. this process is called fermentation and is the process by which alcohol is made. It is important to understand that yeasts work better in warmer conditions than they do in cold conditions. So if its warm and damp or moist it will start to ferment and give off carbon dioxide which is what makes bread and cakes rise. However too high a temperature and the yeast is killed off.


What will happen if yeast powder is put in sugar solution and kept for few hours?

When yeast powder is added to a sugar solution and left for a few hours, the yeast will begin to ferment the sugars, producing carbon dioxide and alcohol as byproducts. This process is known as fermentation. The carbon dioxide will cause the solution to become bubbly and may lead to the formation of foam on the surface. Over time, the alcohol content will increase, and the mixture may develop a slightly sour taste due to the production of organic acids.

What happens when you put 1 teaspoon of yeast in a test tube and leave for half an hour?

Pretty much nothing, unless you put it in warm water with plenty of sugar, in which case the yeast will convert the sugar to ethanol and carbon dioxide


What happens when you put a teaspoon of yeast in a test tube with a pinch of sugar and leave it for half an hour?

If both the yeast and the sugar are dry, then nothing. However, if you mix them together with warm water, the yeast will ferment the sugar and produce ethanol and carbon dioxide.


What happens when you put sugar and yeast inside of a ballon?

If there is a little moisture too, then the yeast cells will multiply and turn the sugar into alcohol and carbon dioxide gas. The carbon dioxide gas will inflate the balloon.
