|
list simi and difference between eukaryotes and prokaryotes?
|
euk :
- orgenalles - cell nucleus - cytoskeleton - larger |
|
|
what is the gen function of membrane
then the function of membrane specically to mitochondira and chrlolplast |
generally resticts and controls movement
specially ir control ph gradient prodcued by electron transport |
|
|
what is the orgin of chrloplast and mitchondria in eukaryotes
|
they are thought to be orianally been prokaryotic orgaisms that became endosymbiouts
|
|
|
what is noncovalent interaction is responsible for creating membrane
|
hydrophobic
|
|
|
the macro structe formed by associton of molecules
and what is this caused by |
membrane
hydrophobic interaction |
|
|
what feature of water structure accounts for its relatively high freezing point specific heat and heat of vaporization
|
the ability to form 4 hydrogen bonds
|
|
|
the properties of water dominate the chemsitry of living organisms. there are two reasons for this. what are they?
|
1. the ability of water to form up to 4 hydrogen bonds
2. its high concentration |
|
|
what non covalent interactions are affected by the solvent water and how are they affected and why
|
h bonds weaken by competioton
electrstatic interactions weaken because of the high diaelectric constant of water hydrophobic interactions stregthen because of exclusions by water. |
|
|
what noncovlent interactons are affected by the solent of water
|
hydrogen bonding
electorstatic interactions hydrophobic interactioins |
|
|
water unusual prop such as high melting point etc. these are derived fomr the ability for water to fomrr
|
hydrogen bonds with one another
|
|
|
the ability for water to form bonds with another water
|
derived from electronegativity
|
|
|
property that allows the hydrophobic effect
|
hydrogen bonding
|
|
|

|
|
how are the side chains of amino acids residues oreinted in alpha helices and beta sheets, relative to the axis of the helix and plane of the sheet
|
1. side chains radiate outward perpendiculat to the helix axis
2. the side chains point aternately up and down telation to the plane of the sheet |
|
|

|
to predict / prédire
|
|
|
what is the function of the alpha helix
|
stablization of the transition state
|
|
