in the mito matrix

3

the primary structure of a protein determines the

overall 3-D shape of a protein

4

chylomicrons have the

lowest protein density and the highest lipid content

vitamin A

7

enzymes do what

lower the activation energy and increase the rate of the forward and reverse reaction

8

liquid chromatography reveals

different effusion rates due to the separation by size

9

how does hemoglobin bind oxygen

positive cooperative binding

fructose cannot be in the initial reactions of

glycolysis

11

fructose, galactose, and glucose are all

hexose sugars

12

lipid synthesis occurs in the

endoplasmic reticulum

13

fatty acid synthesis occurs in the

cytosol

14

any gluconeogenic precursor must contain

a three carbon backbone

15

involuntary smooth muscles of the GI tract are unable to

synthesize glycogen

16

main site of gluconeogenic function

the liver

17

where does the pentose phosphate pathway occur

in the cytoplasm

18

what is the function of the pentose phosphate pathway

to produce NADPH and ribose-5' phosphate

19

what is NADPH used for

reductive biosynthesis and protection against oxidative damage

20

what is ribose-5' phosphate necessary for

DNA synthesis

21

All oxidative branches of the Pentose phosphate pathway are

irreversible

22

what is the starting point in the oxidative branch of the PPP

Glucose-6-phosphate

23

when ribose-5-phosphate is needed what is converted

ribulose-5-phosphate will be converted

24

what happens to ribose-5-phosphate when it is not needed

it must be converted to glycolysis-necessary compounds

25

what is the most important component for blood clotting

fibrin while platelets and plasmin are also important fibrin is the most

26

isozymes

are substances that catalyze the same reaction but have different structures

27

London dispersion interactions are an example of

induced dipole bonds

28

if a bond is nonpolar than it must have what interactions

induced dipole-induced dipole interactions

29

prochiral

are those molecules that can be converted from chiral to achiral in one step

30

what is the rate limiting step of DNA replication

time needed for the polymerase to clamp on

31

endopeptidases

are specific enzymes that cleave peptides at a particular point

32

exopeptidases

cleave at the ends of peptides

33

paper chromatography

will have the nonpolar substance travel further than the polar substance

34

sedimentation coefficient

ribosomes make subunits that include the sedimentation units such as 30S, 40S etc.

35

mg2+ in polymerization acts as a

catalyst

36

hemoglobin displays cooperativity that is

greater than 1 on the hill coefficient

37

hill coefficient displays

cooperativity with 1 being positive cooperativity and -1 being negative cooperativity and 0 having no cooperativity

maternal imprinting

means that the gene inhereted from the mother is not passed on or expressed. (inactive)
