Carbohydrates
Do carbohydrates have long-lasting or short term energy?
Quick!
What are some examples of lipids?
Waxes and olive oil.
What do enzymes do?
They speed up the process of chemical reactions.
What is the main function of nucleic acids?
They store and transport genetic information.
What are the four macromolecules and their monomers?
Carbohydrates and glucose, lipids and fatty acids, proteins and amino acids, nucleic acid and nucleotides.
Which of the following are rich in carbohydrates?
1. Pasta
2. Bread
3. Rice
4. Pineapple

What are the main functions of lipids?
Long term energy storage, insulation, and cushioning of vital organs.
What are structural proteins used for?
Support throughout the body.
What are the two types of nucleic acids?
DNA and RNA.
What is a catalyst?
A catalyst is a substance that increases the rate of a reaction without itself being consumed. They CANNOT be reused.
Carbon, hydrogen and oxygen in a 1:2:1 ratio.
What are lipids composed of?
Carbon, oxygen and hydrogen.
What are proteins composed of?
Chains of amino acids. Amino acids are composed of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.
What is the main difference between DNA and RNA?
RNA is single stranded, and DNA is a double helix.
What can alter the reaction rate of enzymes?
pH, temperature and the concentration of the substrate.
Which carbohydrates are used as structural material in plants?
What is the monomer of lipids?
Fatty acids.
What is the monomer of proteins?
Amino acids.
What nucleotides compose DNA?
A nitrogenous base: Cytosine, Guanine, Adenine and Thymine. CG AT
What is the difference between monomers and polymers?
Monomers are the building blocks of organic molecules, while polymers are the larger form of the said building blocks.
What is the monomer of carbohydrates?
Glucose.
What do phospholipids do?
They help control the movement of molecules in and out of the cell.
What do contractile proteins do?
They help control movement.
What is the structural formula of nucleic acids?
A phosphate group, pentose sugar (Deoxyribose or ribose), and a nitrogenous base.
What is the cell cycle in order?
Interphase, Prophase, Metaphase, Anaphase, Telephase, and Cytokinesis.
