Respiration requires enzymes to catalyze the oxidative breakdown of glucose, the respiratory substrate for respiration. Enzymes in yeast require an optimum temperature of about 30-40 degree Celsius. Hence temperature is closely tied to the rate of respiration in yeast.

Most textbooks and cook books have different ranges on how high the temp must be before yeast dies, but most agree with a 138•f to 140•f

Yeast kills ants since through the contact with water it rises or grows and therefore kills them to the inside out.

Yes as it kills the infection the yeast multiplies.

How does temperature affect reparation rate of yeast?

Yeast does different things based on temperature.

What happens when you mix warm honey yeast and powder sugar?

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

What temperature does yeast start working?

The ideal temperature for yeast growth is 100 to 115 degrees F, but for leavening purposes, the ideal temperature is 80 to 95 degrees F. If the yeast grows too quickly, it will produce large bubble pockets in the bread. Yeast begins to die at 120 degrees F. So it's important to let your yeast dough rise in a spot where the temperature is stable. The cooler the temperature, the slower the yeast grows. It will grow in the refrigerator, but very slowly. I don't know the minimum temperature for it to grow.

Can penicillin cause a yeast infection?

It can yes...happened to me before. It is not that the penicillin gives you the yeast problem. The penicillin kills off bad microbes and those of value, too. So it can permit unbalanced overgrowth of some microbes - which could result in a yeast infection.

How does the temperature of water affect the growth of yeast?

Yeast need warm temperatures in order to grow. The perfect temperature for yeast is about 110 degrees F. Yeast will not start to reproduce and rise without warm temperatures to activate it.

What is the temperature of a yeast environment?

The temperature of a yeast environment will have to be at 100 degrees Fahrenheit. Warmer temperatures will start to kill off the yeast, while colder temperatures will make it go dormant.

Why doesn't yeast rise in hot or cold temperatures?

If the temperature is too low, the yeast will remain dormant. If the temperature becomes too hot, the yeast organisms will be overwhelmed and killed before they can respire.

Does yeast use up the carbohydrate in flour?

No yeast does not use up the carbohydrates, but it does consume some of them to generate the carbon dioxide to cause the dough to rise before the heat of the oven kills the yeast.

What happen when bleach plus yeast plus sugar are mixed together?

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.
