Lipids
Will not dissolve in water.
What is hydrophobic?
Will readily dissolve in water.
What is hydrophilic?
What are proteins made of?
Chains of Amino Acids connected by peptide bonds.
The building blocks of nucleic acids.
What are nucleotides?
What does it mean for something to be organic?
Containing carbon molecules
The double layer of lipid molecules that forms the protective cell membrane.
What is the phospholipid bilayer
What is the function of carbohydrates?
Primary source of daily short term energy.
What are the primary functions of proteins?
Transport, structure, movement, hormonal secretions, enzymes, defense, etc.
This double stranded nucleic acids store genetic information.
What is DNA?
Do not interact with or dissolve in water, polar molecules. Do dissolve in other fats and oils
What is Hydrophobic
Are lipids polar or non-polar?
Non-polar
How can you tell whether a carbohydrate is a monosaccharides, disaccharide, or polysaccharide?
Look at how many 5-carbon rings that is has.
What determines the function of a protein?
The structure and shape, as well as the sequence of amino acids.
This single stranded nucleic acid turns genetic information from DNA into functioning proteins.
What is RNA?
Readily dissolve in water due to favorable interactions with water, a polar solvent
What is hydrophillic
What are the functions of lipids? (there are four, each for 100 points)
1) Long term energy storage
2) Structural support
3) Thermal insulation
4) Hormonal regulation
These polymers are composed of dozens, hundreds, or thousands of monosaccharides and function in energy storage or structural support
What are polysaccharides?
What are the four levels of protein structure? (100 points each)
1) Primary: linear sequence of amino acids
2) Secondary: folding of primary structure
3) Tertiary: three dimensional structure of protein chain
4) Quaternary: arrangement of multiple folded protein subunits into a functional unit
Each nucleotide is composed of: (three things)
1. A nitrogenous base.
2. A sugar
3. phosphate group
The presence of both hydrophobic and hydrophilic regions in the cell membrane determines....
...which substances can interact with, enter, or leave cells
What are lipids made of?
This polysaccharide provides structural support in plant cell walls.
What is cellulose?
This process joins amino acids together by removing a molecule of water.
What is dehydration synthesis?
this describes the general flow of genetic information in cells
The Central Dogma: DNA → mRNA → amino acid chain → protein
