Anyone have any questions on these topics, feel free to post!
I have no idea why i looked at this thread.
how do you explain the quatum theory (chemistry) to a grade 12
and how do you connect it to bohr’s experiment
umm. in Australia that is year 11. Ok in what reference to Bohr’s experiment. perhaps you can explain electronic configeration or the shells. I dont know, you tell me.
I hate brilliant people!
the quatum theory and the light spectrum
Quantum theory basically says that energy can only exist in discrete quanta (basically specific amounts that increase in jumps). This is related to the shells – for an electron to become “excited” (or jump) to a different shell, it has to gain that specific amount of energy.
I’m not sure which experiment you are referring to, but if you mean the one involving hydrogen spectra, it’s basically like this:
He filled a tube with hydrogen gas and shot some electricity at it. The tube then emitted light. However, instead of seeing a nice contiguous rainbow of colours, he saw discrete, disconnected bars of colour. The reason for this is because the electrons in the hydrogen gas were absorbing these specific quanta of energy they needed to become excited to a higher shell. However, electrons don’t particularly like to be excited – they like to be in the “ground state”, or shell number one. Therefore, they immediately hop back down to the ground state and EMIT this energy they absorbed as LIGHT.
Now to the quantum theory: Since the electrons could only absorb specific quanta of energy to become excited, they can only emit the same quanta of energy when they hop back down! This is why only certain colours were emitted from the tube. Each colour corresponded to a different energy lever which corresponded to a different shell of the hydrogen atom.

thanx for starting this thread
now i’ve got no questions but when ill have one ill ask!
What number is a counterexample to this rule- “the square of all numbers is a positive number”
if i understand correctly it means that energy does not behave like a wave but rather like a particle. that particle of energy contains a certain amount of energy. when absorbed by an electron the electron is excited and jumps a shell when the electron goes back to its stable state it releases a photon this is the light that we see.according to the amount of energy that the electron absorb the light of the photon will differ.
Studying for the MCAT?
OK I’ve got one for you – what is the role of hexokinase in energy synthesis?
Oh, and what are the physical symptoms of dopamine antagonism? What are the different types of dopamine inhibition and how do they affect behavior?
Just one more – does Math include statistics?
If so can you please explain to me Poisson equations? I actually have to program it for work and can’t quite get it.
(PS all the above are stuff I’m currently working on)
And to provide an answer – Koillel101 are you thinking of irrational #s?
I don’t believe that’s possible with real integers.
Irrational numbers are no good either.
OneofMany – now you have me curious.
The square of any real number is positive. You were referring to i, no?
Which is the last enzyme involved in glycogenolysis?
I’m assuming you mean “glycolysis” 🙂
Haha no I mean glycogenolysis (the conversion of glycogen to glucose). If you want, I can take over this thread for you.
what are the 2 of you studying in that you know all this?
(and even i knew glycolosis and glyconeogenesis are 2 dif things)
i hear but you didn’t answer my other q
Whoops! Complete misunderstanding. Simple answer – glycogen phosphorylase.
Nah, that’s the first enzyme. Answer is phosphoglucomutase in the muscle, and glucose-6-phosphatase in the liver.
Don’t worry, you’ll learn all this in medical school, if that’s what you’re studying for. 🙂
Are you taking the MCAT? I never went to college, but I took a practice one just for fun. I got a 38. That doesn’t sound very good, but someone told me it is good because it is only out of 45, not out of 100.
So a 38/45= .84, so it is like an 84 out of 100. It still doesn’t sound very good, but I guess it was better than this guy got.
But doesn’t phosphoglucomutase convert glucose-1-phosphate to glucose-6-phosphate? Or am I mistaking that with another enzyme?
Yes, that is correct.
And tro11-
While I’ve got you here – what’s a good book to study anatomy before med school? I’m in my gap year right now, and I would like to get a head-start before med school.
Thanks!
Well the textbook I used was Moore’s Clinically Oriented Anatomy, which is a good book, but I don’t know if you should get it yet if you might use a different textbook in your school.
Yeah definitely get Netter’s Atlas – you will definitely need it.
Hey, I’m looking for a good hand book now. (of course I mean anatomy of the hand/wrist) any suggestions?
They’re okay – I don’t think I would buy them, but they might be helpful if you want to get a head start and have the patience to sit through them.
@ thecuriousone –
Guyton’s “Textbook of Medical Physiology”. That’s physiology, not anatomy, but I think it will give you a much better headstart. Physiology (on the cellular level) gives you a really good insight into life.
Thanks, the curious one.
What about Poisson and dopamine?
Tro & curiousone -I hate Biochem along with everything else you mentioned. I hope Bezras Hashem I don’t remember a thing about any of those subjects (only during test time). Also, you better get a good DVD or CD program on anatomy because when you get to your Surgery rotations you won’t know what anything is, like most students. Not that I knew everything, but I knew more than most clowns. Also get a medical terminology book to study from beforehand, like Shiland’s or Davi-Ellen Chabner’s. And also buy a Physical Diagnosis book like Swartz’s. If you finish these get a Pathology book. Goljan wrote Rapid Review Pathology. All these I have -doesn’t mean that these are the best -there might be better ones.
Oh, Yes. I’m the great pretender…… everyone sing along. What? no one remembers The Platters?
“Also get a medical terminology book to study from beforehand, like Shiland’s or Davi-Ellen Chabner’s”
AHH yes, two great books for the ALLIED health practitioner, heh heh…If I could guess…. I would say these books make up a suggested reading list for a paramedic course. Close huh?
(i)sqd isnt -1 but +1 b/c a negative times a negative is always positive,
but to get a negative # wen sq rooting sumthing u wud need to be sq rooting a negative #, for example the sq root of -12 so then u would have i times sq root of 12, so u wud get
2i(sq root of 3)

Funny I don’t recall posting to you, but you seem to have to constantly post about/to me. What – you don’t have a spouse to annoy?
And your posts are getting dumber by the minute. Since when do Medic courses require Med. Terminology? Maybe you’ll find a few, but most don’t require it. It’s time for you to learn about what is going on around you in the medical field, even though you are just a Nurse’s Aid in an ICU!
Come on Health, what are you? Tell us, tell us, then we will stop bothering you.
We don’t even know who you are so just tell us what you do. Are you a nurse?
i have a physics question:
why when on a merry-go-round, especially a fast one, you can clearly feel the circular motion and some even get dizzy,
but we dont feel the rotation of the earth?
the merry-go-round is only moving a few miles per hour
the earth is rotating at over 1,000 miles per hour.
