What else can I help you with?
What must be added to an aqueous solution of glucose to convert it into ethanol?
Yeast is added to the aqueous solution of glucose to convert it into ethanol through fermentation. Yeast enzymes break down glucose into ethanol and carbon dioxide.
What is the effect of yeast and sugar solution?
When yeast is added to a sugar solution, the yeast ferments the sugar to produce carbon dioxide gas and alcohol. This process is used in baking to make bread rise and in brewing to make alcohol.
What will happen when yeast is added to a solution of glucose?
The yeast will consume the glucose through the process of fermentation, producing carbon dioxide and ethanol as byproducts. This will result in the production of alcohol and the release of gas bubbles, making the solution bubbly and causing it to rise or foam.
What would happen if you put a sample of the yeast and sugar solution in the refrigerator?
Putting the yeast and sugar solution in the refrigerator will slow down the fermentation process because the cold temperature will decrease the metabolic activity of the yeast. This will result in a longer fermentation time or potentially halt fermentation altogether until the solution is brought back to a warmer temperature.
Is Yeast solution reversible or irreversible?
Yeast solution is reversible because yeast cells can proliferate and grow under suitable conditions, such as in a nutrient-rich environment with the right temperature and pH. However, if the conditions are not optimal, the growth and activity of the yeast may slow down or cease, making it reversible.
What must be added to an aqueous solution of glucose to convert it into ethanol?
Yeast is added to the aqueous solution of glucose to convert it into ethanol through fermentation. Yeast enzymes break down glucose into ethanol and carbon dioxide.
Does yeast ferment lactose?
Yes it does.
Are yeast cells lactose intolerant?
yes they are

What organisms can ferment lactose?
some prokaryotes mammalian muscle cells yeast
What is the composition of spirit blue agar?
Spirit blue agar contains peptone, yeast extract, lactose, agar, and spirit blue dye. The dye is added to visualize the digestion of lactose by bacteria, allowing for the differentiation of lactose-fermenting and non-fermenting organisms.
What products are formed when lactose is fermented by bacteria?
yogurt, yeast, mold
What will happen if yeast powder is put in sugar solution and kept for few hours?
When yeast powder is added to a sugar solution and left for a few hours, the yeast will begin to ferment the sugars, producing carbon dioxide and alcohol as byproducts. This process is known as fermentation. The carbon dioxide will cause the solution to become bubbly and may lead to the formation of foam on the surface. Over time, the alcohol content will increase, and the mixture may develop a slightly sour taste due to the production of organic acids.
How can one effectively grow yeast for beer production?
To effectively grow yeast for beer production, one should start by creating a sterile environment and preparing a nutrient-rich solution for the yeast to thrive in. The yeast should be added to the solution and allowed to ferment at the optimal temperature for the specific yeast strain being used. Regular monitoring and maintenance of the yeast culture is important to ensure healthy growth and fermentation.
Can yeast ferment galactose and lactose?
check out this link: http://www.madsci.org/posts/archives/2005-11/1132509463.Cb.r.html what it basically says is that yeasts cannot use lactose becasue they cannot break it down into its components (galactose and glucose), so they can only use lactose when they are genetically engineered to produce lactase (an enzyme which breaks down lactose into its constituent sugars).
Do yeast equally utilize all sugars?
Yeast cannot utilize all of the sugars equally well. While glucose, sucrose, and fructose all can be metabolized by yeast, lactose is not utilized at all. Yeast may not have the proper enzymes to either transport lactose across its cell membrane, or it may not have the enzyme needed to convert it from a disaccharide to a monosaccharide.
