Final answer:
The brewing process includes steps such as photosynthesis, germination, enzymatic digestion of starch, fermentation, and consumption and cellular respiration in sequence. The balanced chemical reaction for the fermentation of glucose is: C6H12O6 -> 2 C2H5OH + 2 CO2. Option B.
Step-by-step explanation:
To understand the correct order of biological processes during brewing, we need to put the provided steps into a sequence that reflects how they occur in the natural production and preparation of ingredients for brewing, particularly beer:
Photosynthesis - Plants, such as barley, use sunlight to convert carbon dioxide and water into energy-rich sugars.
Germination - Barley seeds begin to sprout, breaking down stored starch into simpler sugars that can be used in brewing.
Enzymatic digestion of starch - Microbial enzymes, like amylases, further break down the starches into simple sugars that are fermentable.
Fermentation - Yeast consumes the simple sugars, and through a process called alcohol fermentation, they are converted into ethanol (alcohol) and carbon dioxide (CO2).
Consumption and cellular respiration - The final product (beer) is consumed, and our cells use the ethanol and other nutrients, converting them into energy through cellular respiration, which releases CO2 and water.
The balanced chemical reaction for the fermentation of glucose is:
C6H12O6 -> 2 C2H5OH + 2 CO2
This equation indicates that glucose (C6H12O6) during fermentation is converted into ethanol (C2H5OH) and carbon dioxide (CO2), a critical step in beer production. So otpion b.
