Question

What type of reaction occurs when large carbohydrate molecules are broken down into smaller sugars? select one:

Answer 1

Answer: D

Carbolic reactions breaks larger substances to smaller ones.

Anabolic reactions forms larger compounds from smaller units.

DNA synthesis does not involve breaking down of sugars.

Dehydration is a umbrella term used for reactions that releases water as a byproduct. In the case of sugars, they are held by Glycosidic bonds. To break them, hydration is needed as 1 water molecule breaks 1 glycosidic bond. The process of forming large units of sugars involves dehydration to form the glycosidic bonds. Therefore option d is wrong.

DNA guiding production of protein is definitely wrong as this process doesn't cause sugars to break down at all.
