What is the function of a carbohydrate?
supply your body and brain with energy
100
What are the building blocks of fats?
glyceride = 1 glycerol + 3 fatty acids
100
Proteins are made up of...
amino acids!
100
What is the name of the enzyme model that requires an exact match with it's substrate?
Lock and key model
200
Drawing molecules... an amino acid
200
Drawing molecules... a glucose molecule
200
Where can lipids be found?
oils, fats, nuts, meats, pb, etc
200
What is the function of proteins?
Source of energy – used when carbohydrate levels are low. Structure – build muscles, bone, cartilage, skin and hair tissues
200
Enzymes are made up of...
amino acids!

H2O is an example of an organic substance. True or False
False, a compound needs to have Carbon and Hydrogen for it to be organic.

Name the three disaccharides and what monosaccharides they are made from
maltose = glucose + glucose
lactose = galactose + glucose
sucrose = glucose + fructose
300
What is the chemical make up of lipids?
CHOPN!
Carbon, Hydrogen, Oxygen, Phosphorus, and Nitrogen
300
Two amino acids form a...
peptide bond
300
What is a catalyst?
Speeds up chemical reactions
400
What does the brain use for it's primary source of energy?
carbohydrates!

What are the three polysaccharides? Where do they come from?
Cellulose = plants (cell wall of plants)
Starch = plants
Glycogen = animals (liver)
400
List three differences between saturated and unsaturated fats
Unsaturated - liquid at room temp, plant based fats, contains 1 C=C bond, bent
Saturated - solid at room temp, animal based fats, linear
400
What are the four different structures of a protein? Describe the process
400
How do enzymes affect activation energy?
More enzymes will increase binding sites for substrate molecules and thus increase rate of reaction.
500
What is the bond that results when two amino acids join?
Ester linkage
500
State how the three polysaccharides differ in structure
Glycogen = branched chain
Starch = linear, one chain
Cellulose = cross-linked net, forms chain like structure (fence)
500
Where does the break down of lipids (fats) take place?
most fats get digested in the small intestine
500
What is an essential amino acid? How does your body retrieve them?
Essential amino acids are organic compounds that your body needs to function. You can get them from eating certain foods
