Dipole Moment correct answers The difference in charge between atoms in a water molecule Water Molecules Interact With Each Other Through _______ correct answers Hydrogen Bonds Why is water liquid at room temperature? correct answers Because the hydrogen bonds within it are constantly breaking and reforming on different molecules (moving around) Shell of Hydration correct answers 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 correct answers The movement of water through aquaporins Aquaporins correct answers Water-Selective Channels How do plants and trees move water upwards from the ground? correct answers 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 correct answers -animal fats or vegetable oils -Hydrophobic, water insoluble Ester Bond correct answers Happens when a fatty acid and a glycerol molecule bond Are Phospholipids Amphipathic? correct answers Yes. They have hydrophobic regions and hydrophilic regions Micelle correct answers 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 correct answers 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? correct answers Through hydrophilic protein channels What are the components of an amino acid? correct answers -Amino Group -Carboxcylic Acid -Distinguishing R-group What kind of bond forms within amino acids? correct answers Peptide Bonds
