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.

Breaks down into microscopic molecules
Fats, oils, waxes, steroids
Monomer: 3 fatty acids + glycerol
Polar head
Non-Polar head
Phospholipids & steroids join together w/proteins in the cell membrane
(&hormones)
Function Made mainly of carbon and hydrogen
(few oxygen) Fat best method of STORING forms cell membranes Insulates nerve cells (myelin) Insulates body (maintains
homeostasis)
How are complex carbohydrates
formed and broken down?
Dehydration Synthesis Combining single compounds into a complex one by removing water
monosaccharide + monosaccharide ----> disaccharide + water C6H12O6 + C6H12O6 ----> C12H22O11 + H2O
(Process forms disaccharides & polysaccharides)
Hydrolysis Addition of WATER to a compound SPLITS it
disaccharide + H2O ---> monosaccharide + monosaccharide
C12H22O11 + H2O ---> C6H12O6 + C6H12O6

Bellchallenge: Describe what you see (at least 3
sentences)
This is an amino acid. It is the monomer for a protein. It contains C, H, O and N. It has 3 groups: an amino group, an R-group, and a carboxyl group. The R-group is considered a variant group because it changes.

Meat
Polypeptide
Amino AcidMonomer: amino acidPolymer: polypeptide
Monomer: Amino Acids
•Contains C, H, O, N•20 types•Has both hydrophobic & hydrophylic ends•Differ in R-group•R-group can be acidic, basic or neutral•Makes polypeptide then makes proteins
Polymer: Polypeptide(peptide means bond)
•Formed by dehydration synthesis•Sequence determined by DNA•3-D and folds to take up less space
Function of Proteins Provides us with building
blocks for life! Also regulate most functions
in a cell. Glycoproteins (antigens) Combines w/DNA to form
chromosomes Turns genes on and off Antibodies (fights disease)
Function of Proteins Provides structure &
strength (fibers) Transports molecules in &
out cells Hemoglobin (transports O2) Enzymes (speeds up rxns)-
has –ase suffix Acts as hormones (insulin)-
many proteins have suffix of -in
Bellringer: Describe in detail what you see in the diagram. (minimum 3
sentences)
This is a picture of ATP. ATP is one type of polymer of a nucleic acid. It is made of adenine, sugar, and 3 phosphate groups.

Which biomolecule has the most energy!?
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?
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!
