What are the building blocks of matter? atoms
What are elements and molecules? A molecule is the smallest particle of a substance that exists independently. A substance that cannot be decomposed into simpler substances by chemical means, and is made up of atoms all with identical number of protons is an element
What is the pH scale used for? On the scale what is an acid, neutral, and base?
What are Acids? Give 2 examples
What are Bases? Give 2 examples
Why is water so important to living things?
What is the function of nucleic acids, what are examples of nucleic acids?
List 3 types of Lipids and what they do?
What is the function of protein in living things?
What are the 4 structures of proteins, which structure is the final completed form?
. Proteins are made up of ______________________. How many are there?
What is a Carbohydrate?
What are the three examples of carbs (that end with saccharide), give a real example of each
What is the difference between a saturated and unsaturated fat?

What is wrong with the chemical equation below? How could you fix it? CH4 + O2 → CO2 + 2H2O (remember the law of conservation of matter=left side has to equal right side for the number of atoms of each element)
What elements make up Proteins, Carbohydrates, Lipids, and Nucleic Acids?
Explain how enzymes and substrates are similar to a lock and key.
When the temperature gets too high or pH levels get too high or low for a particular enzyme what will happen to it? What does denature mean?
