Question | Answer |
---|---|
How many bonds can carbon form? | Four |
Type of bond that holds a single water molecule together | Polar Covalent |
Type of bond that holds one or more water molecules together | Hydrogen |
Why is water polar? | Oxygen is more electronegative than hydrogen |
Which organisms utilize capillary action? | Plants... they can move water against gravity |
What is the monomer for proteins? | Amino Acids |
What is the difference between saturated and unsaturated fatty acid chains? | Unsaturated contain double bonds causing kinks so they are liquid at room temperature and do not contain the most amount of hydrogen. |
What is the monomer for carbohydrates? | Monosaccharide |
What is the monomer for nucleic acids? | Nucleotides |
What are the three components of a nucleotide? | Nitrogenous base, phosphate group, pentose sugar |
What is the monomer for lipids? | None |
What are the functions of carbohydrates in living things? | quick energy source, short term energy storage, structure |
What are the functions of proteins in living things? | Communication, transport, structure, movement, defense, enzymes |
What are the functions of lipids in living things? | Insulation, long term energy storage, water loss prevention, communication (hormones), cell membrane structure (phospholipids) |
