Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If you string together 8 glucoses, how many water molecules will come out?
A
1
B
4
C
7
D
8
Explanation: 

Detailed explanation-1: -Okay, so if we are linking together 100 glucose molecules to make the polymer there will be 99 water molecules, and that would be our final answer.

Detailed explanation-2: -For each molecule of glucose produced: 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction.

Detailed explanation-3: -Five molecules of water are produced from this reaction. Monomers are joined through condensation reactions (in this case, a dehydration condensation reaction). Water is a product of the reaction; one water is produced for every bond that is formed. Therefore, six adjoined monomers release five molecules of water.

Detailed explanation-4: -Answer and Explanation: It would require nine water molecules to break down an oligosaccharide containing 10 glucose units.
