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.

Does salt and yeast inflate a balloon?
Live yeast can be used to inflate a balloon if you give the yeast something to ferment (such as sugar). They then produce carbon dioxide as a waste product that could inflate a balloon. You should not expect it to be buoyant, however, for CO2 is heavy as gases go (considerably heavier than air, for instance). The yeast cannot use salt for much of anything, however.
Does salt kill yeast?
I'm pretty sure it's both, because while yeast and flour mixed with water smells alcoholic (which is a sign of fermentation), when it's mixed with yeast and water it smells like milk. Also, it barely grows, less than just yeast and water. Correct me if I'm wrong!
The two main types of fermentations are called?
The two main types of fermentation are aerobic and anaerobic. alcoholic and lactic acid fermentation are two main types
What do yeast glucose and water result in?
The yeast will break down the glucose which produces Carbon dioxide + Ethanol + Energy during anaerobic respiration and the process is also known as 'fermentation'. Carbon dioxide and Ethanol are the waste products. During aerobic respiration, the yeast will produce the same products as we produce such as Carbon dioxide, water and energy.
Can a yeast infection grow worms?
No. It is a yeast, that's all.
How does yeast kill ants?
Yeast kills ants since through the contact with water it rises or grows and therefore kills them to the inside out.
Can penicillin cause yeast infection?
Yes as it kills the infection the yeast multiplies.
What is the difference between boiled and unboiled yeast?
Boiled yeast has been heated to a high temperature, which kills the yeast cells and deactivates the enzymes. Unboiled yeast is live and active, capable of fermenting sugars and producing carbon dioxide. Boiled yeast is typically used in recipes that do not require fermentation, such as bread recipes that call for instant yeast.
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
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.
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.
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.
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.
How does the temperature affects yeast respiration fermentation?
Temperature affects yeast respiration and fermentation because it influences the rate of enzyme activity. Yeast activity increases with higher temperature, up to a certain point, beyond which it decreases due to denaturation of enzymes. Optimal temperature ranges between 25-30°C for most yeast strains.
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.
