CHEM/PHYS

Question 1

if the Keq is 1 that means G is

Answer 1

0, no atp required

Question 2

if g>0 then non spont so it

Answer 2

requires energ - atp

Question 3

visible light spectrum i

Answer 3

400 - 700 nm - where 400 is purple, 700 is red, 530 is green

Question 4

W = 1/2kx2 and when the graph shows the force and distance - use Fd - BUT another way is isolate for k so K=1/2fx - area of triangle

Question 5

power formula

Answer 5

force times velocity

Question 6

if the protein is spont unfolding its this order of rx

Answer 6

zero (M/s) (zero straight line, or linear down)

Question 7

if graph in linear - unimolecular so what order

Answer 7

first order (1/s) (linear or exp slight)

Question 8

units for second order

Answer 8

1/Ms (exponential)

Question 9

hydrophoic =

Answer 9

lipophilic - likes lipid

Question 10

CO2H - what group

Answer 10

carboxyl group

Question 11

if compound is saturated with substrate inc the substrate concentration will/not inc the rte

Answer 11

NOT - it would be a straight horizontal line across

Question 12

if the TNBS binds to the outer membrane faster than the inner and outer membrane can trade places, then the TNBS has just faster rate - makes it more special

Question 13

phophate ion has what charge and it it hydrophilic or phobic

Answer 13

-3, phillic

Question 14

if the diagram shows shape like phospholipid bilayer then should contin

Answer 14

polar and non polar groups, if already psopahte head for polarity, then need to have long chains -for the non polar part

Question 15

acellular PE means

Answer 15

PE not associated with a cell

Question 16

ph ____ as H increases

Answer 16

decreases

Question 17

ph ____ as OH dec

Answer 17

decrease

Question 18

soaps are chem modofed and dereived from

Answer 18

FA, traicyglycerols, phospholipids - all have long carbon chains

Question 19

SQUALENE, a precursor of.

Answer 19

cholesterol

Question 20

for constant flow for a pipe with dec radius, need more energy to main that flow so graph

Answer 20

show the inc - exponential - energy is inverse propr to the radius ^4

Question 21

we dissolve acid in bases, and bases in acids - no common ion effect to shft forward and inc solubility

Answer 21

so to find the ID of the base - add acid to inc solubiity then neutralize with a base

Question 22

fundantal freqeuncy is

Answer 22

n=1 = n is the number of loops

Question 23

fundamental freq formula for closed both ends

Answer 23

F = n x velocity/ 2 times length

Question 24

kd equals to

Answer 24

e s/ES
