Carbohydrates
Name one type of food that contains carbohydrates.
Bread, Pasta, potatoes, etc.
Name a type of food that contains lipids.
What are any fatty foods or any foods derived from living matter.
A type of food that contains a lot of proteins.
What are meats, cheeses, nuts, seeds, or eggs?
The property of having more hydroxide ions than hydrogen ions.
What is basic or a base?
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.
Theoretical pH of plain, old water.
What is 7, or neutral.
this property of water causes it to "stick" to itself.
Cohesion
What is the monomer of carbohydrates?
Monosaccharides
The reason why lipids do not dissolve in water.
What are non-polar / hydrophobic compound properties?
A protein's function depends entirely on its ________________
Shape
What is a pH buffer?
What is a weak acid and its conjugate base or the other way around.
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
Definition of pH
What is the negative log of the free hydrogen ion (H+) concentration expressed in molarity.
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
One example of a protein and its function.
(Moderators choice.) What is myosin and muscle contraction? (And others....)
The pH at which an enzyme works best.
What is the optimum pH?
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.
