Storyboard-Text
- Hi, are you ready for our test on macromolecules?
- Sounds like a great idea!
- Yes, but I would love to review at lunch.
- What are the four types of macrocolecules?
- We have learned about carbohydrates, lipids, proteins, and nucleic acids.
- Yes, carbohydrates contain cabon, hydrogen, and oxygen and are made up of monosaccharides.
- They are a quick source of energy and can be eaten in pasta and bread.
- Lipids are another macromolecule and examples include fats, oils and butter. Lipids store energy for the long term and make up cell membranes.
- Yes, lipids also contain carbon, hydrogen, and oxygen and are made up of triglycerides.
- Proteins are easy to get in our diet as they are found in dairy, meat, and nuts. They also help our immune system.
- The third type of macromolecule is protein. It contains carbon, hydrogen, oxygen and nitrogen and is made up of amino acids.
- The last macromolecule is nucleic acids. They contain carbon, hydrogen, oxygen, nitrogen, and phosphorus and are made up of nucleotides.
- It stores and transmits genetic information and examples are DNA and RNA.
