amoeba sisters: biomolecules video recap part 1
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
\ if it best applies to nucleic acids
c i am useful for a fast source of energy.
p i have involvement in the immune system (ex: antibodies).
l i am helpful for long term energy storage.
p i have a large role in muscle development.
c if athletes \pasta load,\ they consume a lot of me.
n a mutation in dna would initially start with me.
l i make up cell membranes.
p enzymes, which can speed up reactions, belong in my category.
l i am important for insulation.
n i contain elements, c, h, o and have a ring - like structure.
n my category includes genetic material.
i can contain long fatty acid chains.

Explanation:

• Carbohydrates ($C$) are the body's quick - energy source. Pasta is a carbohydrate - rich food, so when athletes "pasta load", they consume carbohydrates.
• Proteins ($P$) play roles in the immune system (e.g., antibodies) and muscle development. Enzymes, which speed up reactions, are also proteins.
• Lipids ($L$) are for long - term energy storage, make up cell membranes, and are important for insulation. They can contain long fatty acid chains.
• Nucleic acids ($N$) are involved in genetic material. A mutation in DNA (a nucleic acid) starts with nucleic acids, and nucleic acids contain elements $C$, $H$, $O$ and have a ring - like structure (in the case of nucleotides which are part of nucleic acids).

Answer:

1. $C$: I am useful for a fast source of energy.
2. $P$: I have involvement in the immune system (Ex: antibodies).
3. $L$: I am helpful for long term energy storage.
4. $P$: I have a large role in muscle development.
5. $C$: If athletes "pasta load," they consume a lot of me.
6. $N$: A mutation in DNA would initially start with me.
7. $L$: I make up cell membranes.
8. $P$: Enzymes, which can speed up reactions, belong in my category.
9. $L$: I am important for insulation.
10. $N$: I contain elements, $C$, $H$, $O$ and have a ring - like structure.
11. $N$: My category includes genetic material.
12. $L$: I can contain long fatty acid chains.
