July 28th xam - Doubts

[k3nshin]

So instead of making different threads i thot i would just start one in which i will keep adding my doubts

Characteristic of exergonic reactions
dec entropy
inc enthalpy
dec enthalpy
neg free energy change (ans)
pos free energy change

I disagree with the key....I think it should be positive free energy change....energy is released in the environment....also, wouldnt decreased enthalpy be also a choice??

Which is more potent?
Endotoxin or exotoxin?
one of the cards in decks say exotoxin is more potent than endo, n another one says that endotoxin are HIGHLY POTENT....even i think its endotoxin.....wut say?

i'd go with endotoxin too..

exotoxin is more potent than endotoxin. even a small dose of it can cause toxicity.
endotoxin is non toxoidable that is it cannot be neutralized like exotoxin can

incremental lines of salters ..... in cementum
a new dna strand is synthesise in 5'-3' direction
even synthesis of mRNA from dna occurs in 5'-3' direction

cementum doesnt have incremental lines.
incremental lines of salter are transverse lines seen in improperly calcified dentin

well it is true that botulinum n tetanus neurotoxin are all exotoxins, so i geuss then exotoxin is the one i'll go with...
