What is matter
anything that takes up space and has mass
The bond between Na+ and Cl-
ionic bond
The difference between hydrophilic and hydrophobic
Water loving vs water fearing
What is facilitated diffusion
passive transport that requires the use of a membrane protein
provide energy for the cell
What are isotopes
two atoms of an element that differ in the number of neutrons in the nucleus and have different mass numbers
A carbon double bonded to an oxygen atom, found in ketones and aldehydes
carbonyl
The model that describes the structure of a biological membrane with a phospholipid bilayer
fluid mosaic
Two solutions with the same solute concentration
Isotonic
Physical difference between rough and smooth ER
ribosomes are present on the rough ER
Van der waals
molecules or atoms very close together attracted by fleeting charge differences
Name of the covalent bonds that join nucleotides
phosphodiester linkages
Unsaturated fatty acid features
Double bonds present. Usually in the cis configuration
Water movement in a cell in a hypertonic solution
water leaves cell and it becomes shriveled
Cells without membrane bound organelles
prokaryotic
Cohesion vs adhesion
water molecules held together by hydrogen bonds vs water adhering to cell walls to counter gravity
Water's ability to dissolve NaCl
Water is polar, so the partially positive H will attract the partially negative Cl and the partially negative O will attract the partially positive Na
Channel proteins that facilitate the passage of water
aquaporins
What is osmosis
movement of water from an area of high concentration to an area of low concentration
DNA location in eukaryotes vs prokaryotes
nucleus vs. nucleoid
Electron with the greatest potential energy
most distant from the nucleus
The bonds that aid in the attraction of water molecules to each other
hydrogen bonds
Cholesterol's role in phospholipid bilayers
increase fluidity at low temps and prevent excess fluidity at high temps
Type of transport if fatty acids in blood are transported to an adipose cell which stores lipids
diffusion because fatty acids are non polar and don't need a transport molecule
Properties best suited for the metabolic needs of diffusing substances most rapidly from interior to exterior and vice versa
Surface area significantly greater than its volume
