Bellringer Describe in detail what you see in
the diagram. (Minimum 3 sentences)
The digestive process is occurring. In order for organisms to live and function they require energy. Eating and digesting food provides the body with chemical energy in the form of ATP.

Explain what you think is happening here. (at least 3 sentences)
The diagram shows a picture of bread (starch). It also maps out the break down of carbohydrates from their most complex form (polysaccharide) to their least complex (monosaccharide). This process is called hydrolysis.

Dehydration Synthesis Combining single compounds into a complex one by removing water
monosaccharide + monosaccharide ----> disaccharide + water C6H12O6 + C6H12O6 ----> C12H22O11 + H2O
(Process forms disaccharides & polysaccharides)

C-H bonds Count the number of C-H bonds
in your monosaccharide picture.
Count the number of C-H bonds in your saturated or unsaturated bond picture
Which biomolecule (carbs or fats) have more C-H bonds?
![Page 44: Bellringer](https://reader035.vdocuments.us/reader035/viewer/2022081520/56816199550346895dd14ced/html5/thumbnails/44.jpg)
The number of C-H bonds = the amount
of energyThe more C-H bonds a biomolecule has, the more energy it has!
Fats have the most energy because they have the most C-H bonds!
