A patient experiences constant stomach pains for the past month. Eventually, doctors decide his gallbladder needs to be removed. This organ normally breaks down fats. Name 3 foods this patient should avoid after surgery.
anything containing fat / lipids : butter, avocado, oil, fried foods like bacon, etc.

What is the dependent variable in this experiment:
Atmospheric CO2 (because it is on the Y axis)
300
Name 2 functions of carbohydrates.
short-term energy and structure in plants

What is the main function of nucleic acids?
store the genetic information that is used to build all proteins in the cell
300
The area that a substrate binds to on an enzyme is called the ___________
active site

A patient has a genetic condition called sickle-cell anemia. This causes red blood cells to curve into a sickle shape, blocking small blood vessels from getting oxygen and other nutrients. What macromolecule is responsible for this disease? 
nucleic acids / DNA since this is a genetic condition
400
What words describe molecules that like water?
hydrophilic

An enzyme called lipase binds to a substrate and catalyzes a reaction that breaks the substrate into a glycerol backbone and fatty acid tail. What was the substrate that the enzyme broke down?
a lipid/ fat

Albinism is a genetic condition where individuals do not produce melanin, a pigment normally in skin and hair. They will have very pale skin, white or very fair hair, and light colored eyes. What TWO macromolecules are involved in this condition?
nucleic acids because its a genetic condition
protein because melanin is a protein
