• • strings

[B-LS1-6] Organic Compounds2 - Skill/Concept

Which of the following statements best explains how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and other large carbon-based molecules?

• • Carbon, hydrogen, and oxygen can form bonds with other atoms, allowing them to combine into larger molecules.

• • Carbon, hydrogen, and oxygen can form a mixture, allowing them to combine into larger molecules.

• • Carbon, hydrogen, and oxygen can change phases from gas to liquid, allowing them to combine into larger molecules.

• • Carbon, hydrogen, and oxygen cannot form bonds with other atoms, and therefore cannot combine into larger molecules.

[B-LS1-6] Organic Compounds 3 - Strategic Thinking

Which statement supports the claim that glucose acts as a building block for chitin, a major component of fungal cell walls.

• • Chitin is found on the outside of the fungal cell membrane.

• • Chitin is made up of repeating sugar units.

• • Chitin is also found in the exoskeletons of insects.

• • Chitin is a carbohydrate.

How would a sugar molecule serve as the basis to build a lipid molecules?

• • Sugars have the same structure as lipids, but with different elements. 

• • Sugars provide the phosphorus and nitrogen used to build high-energy lipids.

• • Sugars provide the carbon, hydrogen, and oxygen used to build a lipid.

• • Sugars provide the energy for the cell to build lipids from raw materials.
