Can this page ALSO help me with Bio??
If it can
Can someone please help me:
My school gave us waaaaaaaaaaay too much information..
And I just want to be sure:
When making cheese,bread, wine,yoghurt, and beer, what do we have to know EXACTLY
Our school gave us steps and all those stuff
Should we ONLY know what the study guide tells us on this part (the results, and a brief explanation)
You need to know the steps ofc.
We have yoghurt making, baking, brewing
Yeast can respire without oxygen, fermenting sugars to produce carbon dioxide and alcohol.
In baking:
-a mixture of yeast and sugar is mixed with bread dough;
-the mixture is left in a warm place;
-carbon dioxide, produced by the yeast respiration, causes the bread to rise;
-the bread is then baked.
In the production of yoghurt:
-a starter culture of bacteria is added to warm milk;
-the bacteria ferment the milk sugar (lactose), producing lactic acid;
-lactic acid causes the milk protein to form a solid material.
Brewing
-Yeast respires sugar to form ethanol and CO2
-The source of sugar is usually fruit juice or grain
-The ethanol makes the drink alcoholic; carbon dioxide gives the drink its fizz. The process is called fermentation
This is all we need to know By the way
