Amoeba sisters video recap: biomolecules directions: for each statement, write a "c" if it best applies to the carbohydrates, "l" if it best applies to lipids, "p" if it best applies to proteins, or "n" if it best applies to nucleic acids. 1. i am useful for a fast source of energy. 2. i have involvement in the immune system (ex: antibodies). 3. i am for long term energy storage. 4. i have a large role in muscle development. 8. enzymes, which can speed up reactions, belong in my category. 11. my category includes genetic material. 9. i am important for insulation. 5. if athletes "pasta load," they consume a lot of me. 7. i make up cell membranes. 6. a mutation in dna would initially start with me. 10. i contain elements c, h, and o and have a ring-like structure. 12. i can contain long fatty acid chains.

Lipids are long-term sources of energy, whereas carbohydrates are short-term sources of energy. On the other hand, proteins, lipids and carbohydrates may have structural, regulatory, and metabolic properties.

In regard to the questions above:

Carbohydrates (i.e., simple carbohydrates such as glucose) are useful as a fast source of energy.Proteins are involved in the immune system (ex: antibodies). Antibodies are proteins belonging to the immunoglobulin family.Lipids are helpful for long-term energy storage.Proteins have important roles in muscle development. Actin and myosin are the main proteins in the muscle cells.Plates of pasta are mainly composed of complex carbohydrates. These carbohydrates (complex) are mainly present in foods such as bread and pasta.Nucleic acids are either DNA and RNA. A mutation is any change in the DNA sequence, i.e., any change in the nitrogenous bases that form this nucleic acid.Lipids are the main components of cell membranes. The main lipids that form biological membranes are phospholipids and cholesterol.Enzymes are generally proteins that can speed up reactions. The exceptions to this rule are ribozymes, which are made up of RNA. Nucleic acid (DNA) is the genetic material of all organisms.Lipids have important roles associated with heat insulation.Carbohydrates contain elements C, H, and O and may have a ring-like structure (e.g., ribose or deoxyribose).Lipids may contain long fatty acid chains. For example, phospholipids are composed of two long fatty acid chains and one polar phosphate group which are attached to a glycerol molecule.

In conclusion, lipids are long-term sources of energy, whereas carbohydrates are short-term sources of energy. On the other hand, proteins, lipids and carbohydrates may have structural, regulatory, and metabolic properties.
