sugar
Because yeast needs to have food just like us to grow, and sugar is that food.
the 4 conditions needed for yeast to grow are: 1. Warmth 2. Moisture 3. Food 4. Time
Yeast needs warmth, food and moisture to grow while bacteria needs warmth, food , correct ph,oxygen, and time to grow. Moulds need warm, moist conditions and viruses need time and opportunity for the conditions to be right for them to thrive.
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
So that the yeast has food to grow.
Most bacteria will grow in dark, moist, warm areas with a neutral PH balance (ph7, water, sweat, most foods) and a source of food for the bacteria, such as sugars, and protein. All bacteria need to grow in conditions such as this is time. (And not very long, either. 4 hours on average)
The heat provides energy for the enzymes in the yeast to work. If the water is to hot however, the enzymes will be denatured, and the yeast will not grow.
Yes.
bread uses yeast to grow. Yeast makes the bread nice and fluffy. :)
the helpfull food is very good it has yeast with helps bread grow
u take it and pour it into a baker
As anyone who bakes bread, or brew wines and beers will know, yeast needs a moist, warm environment in which there is dissolved liquid sugar available (not salt). The yeast cells rapidly multiply as the yeast feeds off the sugar, and gives off carbon dioxide gas and alcohol. It is the carbon dioxide gas that will inflate the balloon. Salt would probably kill off the yeast.
