| Question | Answer |
|---|---|
| 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 are the building blocks of DNA and RNA called? | |
| What is the structure of DNA called? | |
| Why is the element Carbon so important to life? | |
| . In a chemical reaction, what are products and reactants? | |
| What is a chemical reaction? | |
| What are exothermic and endothermic mean? | |
| The energy needed to start a chemical reaction is called_________________? | |
| What is an enzyme? | |
| What is the difference between anabolic and catabolic reactions? Give 1 example of each | |
| Why are enzymes so important to life? Name 3 enzymes and give their functions | |
| The reaction rate of enzymes depends on what main conditions? | |
| What is the law of conservation of matter? | |
| Water is a polar molecule, what does that mean? | |
| What is metabolism and how is that related to water? | |
| Water is held together by what kind of bond? | |
| 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? | |
| What are 5 properties of water that help explain why life can exist? | |
| Why don’t denatured enzymes function? | |
| What are the monomers of carbohydrates, lipids, and nucleic acids? |
