bio/biochem

Question 1

glucose

Answer 1

active transport in gut and facilitated diffusion elsewhere

Question 2

17 C fa and 7 rounds

Answer 2

7 all and 1 propionyl coA

Question 3

18 C and 8 rounds

Answer 3

9 AcoA and 8 others

Question 4

carboxylase

Answer 4

add CO2

decarbox= remove Co2

Question 5

cholesterol to mevalonate to

Answer 5

isoprene to squalene

Question 6

glycogenesis

Answer 6

glycogen synthase

glycogen phosphorylase (lysis and also debranching enzyme does hydrolysis alpha 1,6)

Question 7

high salt concentration

Answer 7

denature proteins but stabilize DNA

Question 8

actin (microfilament)

Answer 8

provide structure to cytoskeleton

Question 9

ANP

Answer 9

increase Na in urine

Question 10

constriction in arterial system (not veins)

Answer 10

increase BP and decrease Q

Question 11

veins are less elastic than arteries

Answer 11

thinner

Question 12

systematic veins

Answer 12

deoxyg, ACIDIC umbilical veins (oxy)

Question 13

cost signaling

Answer 13

altruism (inclusive fitness)

Question 14

acrosome rxn then cortical rxn (egg ejects cortical granules that prevent other sperm to bind)

Answer 14

gastrulation= notochord form (primitive streak)
neurolation= ectoderm (CNS and PNS)

Question 15

parvocellular pathway

Answer 15

form, color (spatial)

magno (motion, temporal lobe !!!)

Question 16

mouth

Answer 16

no enzyme for PROTEINS (only lubrication, mastication )

Question 17

secondary active transport

Answer 17

glucose (Na pump) to go inside the small intestine

aa same think to get in and both exit through facilitated diffusion !!!

Question 18

stomach

Answer 18

no lipid/carb digestion, only protein

Question 19

CCK releases

Answer 19

pancreatic lipase, protease !! also secrete bile so that it emulsifies lipids (chylomicron)

Question 20

emulsification

Answer 20

lipids covered with micelle (lump together)

Question 21

vitamins

Answer 21

not produced in the body

Question 22

ligament

Answer 22

bone to bone

Question 23

Homologous structures share a similar embryonic origin

Answer 23

Analogous organs have a similar function.

Question 24

PTH (act on kidney)

Answer 24

calcitriol (small in)

Question 25

calorimetry

Answer 25

combustion rxn (CO2+ water) exothermic (release heat)

O2+ something= CO2 +water

Question 26

esterification of fatty acid

Answer 26

fatty acid synthesis gibi dusun

Question 27

ice gives water heat (cold)

Answer 27

endothermic

Question 28

making bond

Answer 28

exothermic

Question 29

ATP breaking bond is

Answer 29

the electric PE makes it exothermic not the bond energy \

bond energy is + !!(endo)

Question 30

breaking bond (bond dissociation energy)

dissociation !!!! so the values are positive

Answer 30

endothermic

break up is emotional so you need E

Question 31

exergonic

Answer 31

G is negative/spon (losing E) less E in the products

Question 32

When Q bigger than Keq

Answer 32

favors reactants

G= G (standard) + RTln (Q)

or

G= RTln (Q/K)

increase temperature increases the k (rate of reaction) !!

k= Ae formula !!

Question 33

zero order

Answer 33

the compound doubles

rate of rxn doesnt change

Question 34

first order

Answer 34

same values for both rate and compound increase

Question 35

intermediate

Answer 35

first product than the reactant

catalyst= first reactant than P

mostly the catalyst involved rxn is the slowest step !!

Question 36

adding HCl to a soap gives

Answer 36

free fatty acids so that it can be neutralized with NaOH

Question 37

guanine is big

Answer 37

it has 2 donors and 1 acceptor

Question 38

carnot engine

Answer 38

work is done by the engine

Question 39

compression

Answer 39

work is done on the system so POSITIVE

Question 40

methyl orange and phenolalphtlein

Answer 40

weak acid

Question 41

intrusion errors

Answer 41

false info report (memory is reconstructive)

Question 42

plasmin

Answer 42

protease that break down clot
