yeh i thought it would be cool to do this ... would it be achoholic
What will happens to the bottle with yeast and sugar solution is placed in hot water?
Yeast is a fungus and it produces extracellular enzyme ZYMASE whose activity is optimum in warm upto 35 centigrade condition.So when zymase is provided with warm temperature with the help of hot water it starts its catalytic activity on sugar and FERMENTATION takes place which converts sugar solution into ETHYL ALCOHOL WHEREAS CARBONDIOOXIDE evolves as gas.
Why sugar is important to the growth of yeast?
This is actually not a chemical reaction. Yeast are living organisms and they use sugar as an energy source, so if you put yeast and sugar together the yeast will consume the sugar and give off carbon dioxide. This is why breads made with yeast rise and have small holes in the bread after it is baked - the holes are where small bubbles of carbon dioxide were trapped.
Why wouldn't yeast and water inflate a balloon unless you add sugar?
The sugar is needed as food for the yeast. The yeast gives off carbon dioxide as it digests the sugar. The carbon dioxide could be used to inflate the balloon. Without the sugar, the yeast remains dormant and does not give off carbon dioxide.
What makes yeast grow fastest sugar honey or syrup?
Sugar makes yeast grow fastest when added to it with warm 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
Why does a sugar solution become alcoholic on adding yeast?
Yeast consumes sugar and as a byproduct you get alcohol. In simple terms, yeast eats sugar and pees out alcohol.
What is the Tyndall effect of sugar solution?
Tyndall effect doesn't exist in a sugar solution.
What will be the effect of sugar on turmeric solution?
Sugar hasn't effect.
Why do yeast grow in sugar solution but not in water?
Because yeast needs to have food just like us to grow, and sugar is that food.
What is the effect of sugar solution in turmeric?
No effect
What is the effect of sugar solution on turmeric solution?
when sugar solution is added to turmeric solution , it turns yellow.
Why does live yeast and sugar solution mixed in a water bath of 30 degrees bubble?
Think of the sugar solution as food for the live yeast. The yeast breaks down the sugar by alcoholic fermentation, a process that takes the sugar and breaks it into ethanol and carbon dioxide. The carbon dioxide that forms can be seen by the naked eye...in the form of bubbles!
What is the properties of solution in sugar?
No effect
What conditions is necessary for yeast to grow and multiply?
Yeast require energy to grow and divide its cells, therefore yeast grows best in sugar solution.
Why must the sugar solution be cooled before adding yeast?
It's not clear in what context this question is asked, but hot water can kill yeast.
What is given off when yeast ferments sugar?
Bubbles of CO2 comming out of the solution
