1.B. What properties of carbon explain carbon's ability to different large and complex structures?
Carbon can bond to itself, has 4 valence electrons, causing strong covalent bonds to occur between carbon and another element.

2.A. Name four groups of organic compounds found in living things.
Carbohydrates, proteins, lipids, and nucleic acids.
New cards
31
2.B. Describe at least one function of each group of organic compound.
Carbohydrates: main source of energy for plants and animals; proteins: regulation of cellular transportation of materials, cellular processes, formation of structures, and anti-bodies; lipids: storage of energy; storage or transmission of genetic information.

2.C. Why are proteins considered polymers but lipids not?
Proteins have long chains of monomers, but lipids do NOT made up of components that make up a chain.
