●● Water Molecules Interact With Each Other Through _______
Answer: Hydrogen Bonds
●● Why is water liquid at room temperature?
Answer: Because the hydrogen bonds within it are constantly breaking
and reforming on different molecules (moving around)
●● Shell of Hydration
Answer: The oxygen atoms in water will orient themselves towards
positively charged ions in water, the hydrogen atoms will orient
themselves towards negatively charged ions in water
●● Osmosis
Answer: The movement of water through aquaporins
●● Aquaporins
Answer: Water-Selective Channels
●● How do plants and trees move water upwards from the ground?
,Answer: Water will move across a barrier if one side has more ions than
the other. If aquaporins allow water to move but not ions, water will
continuously flow towards the other side and drain from the other,
causing hydrostatic pressure to form and water to move upwards.
●● Triglycerides
Answer: -animal fats or vegetable oils
-Hydrophobic, water insoluble
●● Ester Bond
Answer: Happens when a fatty acid and a glycerol molecule bond
●● Are Phospholipids Amphipathic?
Answer: Yes. They have hydrophobic regions and hydrophilic regions
●● Micelle
Answer: A sphere of phospholipids with hydrophobic tails on the inside
and hydrophilic heads on the outside. If any water enters a micelle, it
will explode.
●● Liposome
Answer: a sphere with a phospholipid bilayer. Hydrophobic tails face
towards each other inside the outer layer of hydrophilic heads. This is a
more stable structure as water entering it will not destroy it.
, ●● How do proteins move in and out of cells?
Answer: Through hydrophilic protein channels
●● What are the components of an amino acid?
Answer: -Amino Group
-Carboxcylic Acid
-Distinguishing R-group
●● What kind of bond forms within amino acids?
Answer: Peptide Bonds
●● What are the two ends of an amino acid?
Answer: Aminoterminus and Carboxyterminus
●● What is Primary Protein Structure and what kind of bond is
associated with it?
Answer: Amino Acid Chains, Peptide Bonds
●● What is Secondary Protein Structure and what kind of bond is
associated with it?
Answer: Alpha Helix and Beta Pleated Sheets, Hydrogen Bonds
