What are physical change and chemical change?
100
The process by which living organisms produce larger molecules from smaller ones.
What is Biosynthesis?
100
The scale chemists use to track the level of acid or base.

100
These are the basic building blocks of a protein.
What is amino acids?
200
Often called the 'planetary model' of an atom
What is the Bohr model?
200
The three phases of matter.
What are solid, liquid, gas
200
This links atoms together in a molecule
What is chemical bond?
200
Solutions that have a pH from 0 to 7 are this.
What is acidic?
200
The bond that links amino acids together in the process of dehydration and ejects water.
What is a peptide bond?

The catalyst that is used to accelerate this chemical reaction 6CO2 + 6H2O --> C6H12O6 + 6O2
What is chlorophyll?
300
Two different molecules that have the same chemical formula.
What are isomers?
300
These are formed when three fatty acids link to substance know as glycerol in a dehydration reaction.
What is fat or lipids?
300
A special class of amino acids that act as catalysts for many of the chemical reactions that support life.
What are enzymes?
400
Chemicals that result from atoms linking together
What are molecules?

500
We make this substance in our bodies when we have excess carbohydrates to store.
What is glycogen?
500
The difference between saturated fat and unsaturated fat.
What is Saturated fats have no double bonds in carbon atoms, whereas Unsaturated fats have at least one double bond between carbon atoms.
