Okay I have another one.

Our modern understanding of fermentation comes from the work of ______________.

What is Lactobacillus? Is it good or bad? Lactobacillus is most commonly found in what type of foods?

A cube is 2 inches long on each side, the weight of the cube is 4 lb's. What is the density of this cube?

Hi! I did this event last year, but I'm trying to get a refresher!
1. Edward Buchner, I believe
2. Lactobacillus is an organism that produces lactic acid. Lactobacillus is good. It is commonly found in fermented foods, such as yogurt
3. Roughly 227 grams/cubic inch. (4 pounds=1814 grams, and there are 2*2*2=8 cubic inches. 1814/8=roughly 227)

Galactose is the c-4 epimer of glucose.

Maltase?? I'm not sure. -- I'll look into it...

Fermentation occurs in the cytoplasm of cells.

Which sugar is the C-4 epimer of glucose?

Which enzyme breaks down fructose?

Where does fermentation occur?(Be specific)
1. Lactose
2. Fructose-1-phosphate Aldolase
3. Cytoplasm

Ill take up you're challenge,
1. Galactose
2. Sucrase?
3. Fermentation occurs in foods though anaerobic conditions and other bacteria. Those conditions can then cause glycolysis to happen. When glycolysis happens the fermentation process will change into alcoholic fermentation or lactic acid fermentation and etc.

1. What is the difference between hexose sugars and pentose sugars?
2. What is the name of the two groups that polysaccharides are divided into?
3. Where is glycogen found?
1. The two sugars have a different amount of carbon monosaccharides. Hexose sugars have 6 while pentose sugars have 5. 
2. Storage polysaccharides and structure polysaccharides.
3. Glycogen is found in animals.
