Fats and oils for storing energy
What is the definition of lipids?
Helps with structure and stores extra energy
What are the functions of lipids?
They dissolve if a small but still perceptible amount of solute is added, but they do not dissolve if too much is added
What does it mean when it says lipids are semi-soluble?
2 x more
How much energy can lipids store compared to muscle?
Like water
What does it mean to be hydrophilic?
Dislike water
What does it mean to be hydrophobic?

What is the definition of saturated?
Fats with less than the maximum number of hydrogens, double bonds, healthy, liquid
What is the definition of unsaturated?
Phospholipids
What are cell membranes made of?
Make a person unique, provides support and function
What is the purpose of proteins?

9
How many amino acids are essential?
Determines the shape of protein
Why is the order of amino acids important?
Peptide bonds
What type of bonds hold amino acids together?
Might not function
What happens if the shape of amino acids is broken?
DNA, RNA, and polypeptide chains
What are made by nucleic acids?
Contains the genetic information for the development and function of an organism
What is the importance of DNA?
Biological catalyst
What is the definition of enzyme?
Lowers activation energy and increase the rate for reaction to occur
What is the definition of catalyst?
Proteins
What are most enzymes made of?
Catalysis
What does it mean to reduce the activation energy?
Prevents enzymes from functioning (sickness and viruses)
What happens to the function of enzymes if your body is no longer in homeostasis?
1. Substrates bind to an enzyme at certain place called active sites
2. The enzyme bring substrates together and weakens their bonds
3. The catalyzed reaction forms a product that is released from the enzyme
What is the lock and key model for enzymes?
Thing being dissolved
What is the definition of solute?
Thing doing the dissolving

Attraction between molecules of different substances
What is the definition of adhesion?
Attraction between molecules of the same substance
What is the definition of cohesion?
It takes more energy to increase the temperature
What does it mean that water has a high specific heat?
It allows for homeostasis and temperature regulation
What does high specific heat allow to take place on earth and in the human body?
A substance that increases the hydrogen ion concentration of a solution
