Carbohydrates
Name one type of food that contains carbohydrates.
Bread, Pasta, potatoes, etc.
Name a type of food that contains lipids.
There's a lot. Ask Mr. Brown
Name a type of food that contains proteins
a lot. Ask Mr. Brown
Give one example of a Nucleic Acid
DNA, RNA
Water is held together by what type of bond?
Polar covalent bond
What is the purpose of carbohydrates for living things?
Quick energy.
What is one function of lipids?
Long-term energy storage, insulation in animals, cell membrane structure.
What is the monomer of proteins?
Amino Acids.
What is the monomer of nucleic acids?
Nucleotides
this property of water causes it to "stick" to itself.
Cohesion
What is the monomer of carbohydrates?
Monosaccharides
Do lipids dissolve in water? Why or Why not?
No. They are non-polar / hydrophobic.
A protein's function depends entirely on its ________________
Shape
What is the function of nucleic acids.
Stores genetic information.
Cohesion creates this property that allows bugs such as water striders to sit on top of the water without sinking.
Surface Tension
Give an example of a carbohydrate polymer.
Starch, cellulose, glycogen, etc.
This type of lipid is a solid at room temperature.
Saturated Fats
What can change the shape of a protein causing it to denature?
Heat, pH, Salinity
DNA stands for Deoxyribo__________________
Nucleic Acid
Density
What 3 elements make up all carbohydrate molecules?
Carbon, Hydrogen, Oxygen
This type of lipid contains double bonds which bends the molecule preventing it from stacking.
Unsaturated Fats
Give me one example of a protein and describe its function.
Ask Mr. Brown
Describe the shape of a DNA molecule.
Double helix, twisting ladder
This type of bond is created when the positive charge on the hydrogen atom of one water molecule is attracted to the negative charge on the oxygen atom of another water molcule.
Hydrogen Bond.
