i had the same exact question for my science report determining wether or not yeast cells are alive.
To look good
There is no sugar in yeast because it is a living organism and living organisms don't need sugar.
Yeast is a bacteria that feeds on sugar, which causes the fermentation process. In the process of wine making, grapes have yeast in the skin and sugar in the flesh of the fruit, the yeast then feeds on the sugar in the flesh fermenting the juice and making the wine.
warm water - yeast needs warm water to become active. suger is the yeast's food .it gives the yeast the energy it needs to grow. cold water - the cold water kills the yeast (kind of) normal room temperature - the yeast just becomes in active and doesn't react
If you leave a sugar-yeast-water mixture to ferment for too long of a time the gluten will lose elasticity.
Yeast of course, beer bottle, water, balloon and sugar maple syrup.
The bottle that contains only yeast and water. The experimental group in the bottle with yeast, water, AND sugar.
I just did this experiment for my biology class. It seems that with the bleach, it kills the reaction of the yeast. It overpowers the yeast. No bubbles occur--like if it were just yeast, sugar, and warm water.

Presence of sugar in the both bottles
Among other varieties, the basic ingredients for bread are Flour, Water, Sugar, and Yeast.
Yeast Grows much better in sugar water. They are micro organisms that need the sucrose in the sugar to activate and grow, without the sugar very little would happen. If you used salt water it would most likely kill the yeast.
Yeast consumes sugar and as a byproduct you get alcohol. In simple terms, yeast eats sugar and pees out alcohol.
No, combining yeast with sugar will not produce gas. Yeast must be dissolved in water with starch or sugar in order to begin fermentation producing CO2 gas.
To be activated, yeast needs warmth, water, and sugar.
The yeast would eventually starve and die.
