I need a B overall, so I need to get as high a grade as possible in this because I don't think I did very well in f215 :| How about you?

Sensory neurone has a longer axon to transmit over long distances and has shorter dendrites. The other obvious difference is in their function (F214 jan paper all over again

Thank you! I'm just struggling on the Photosynth. and Res. stuff, and I think that's what'll come up. I need a B overall

There's a section in my textbk bout 'evidence of chemiosmosis' do I need to learn this? Has it come up b4?

Ok. Shall we start with your weakest and work our way up? I'll ask you questions that are grade-able categorised? Like C questions to B, then A?

[INDENT]

Oh, that would be awesome! Thank you so much!

Then what's the third difference? I was trying to refer to the idea that the motor neurones' cell body is in the center of splayed out dentrites whereas Sensory wasn't and was between a dentrite and axon...

Can you help me word that right? Lol.

That would probably be experiments right?

Just make yourself familiar about them. They won't probably ask you about it, they'll ask you to apply knowledge around that area..

urm... yeah I see what you mean xD I think the cell body just refers to the area that houses all the organelles and the nucleus

Another difference includes the motor neurone cell body is inside the CNS , the sensory neurone cell body is inside the PNS

Thnx it's mainly bout researchers n their studies but I Cbb even looking at it! Lol I'll just read it then, Thanx

It's alright. Asking questions helps me revise anyway. What's your weakest topic?

Anything to do with Respiration. Definitely.

Ok. Let's start with simples.

What respiration cycle occurs in the matrix of a mitochondrion?

How many cycles/stages are there for respiration of one glucose molecule?

Err.. Glycolosis, and 2 ? :\

Kreb's Cycle.

And Glycolysis once for glucose, Link reaction twice for pyruvate, Kreb's cycle twice for Acetyl CoA.

We don't account oxidative because it uses the bi-products of Kreb's Cycle.

.... Ok. Those were C/B questions. I'll make it simpler, lol. I struggled with that too when I first read it.

What happens to pyruvate in anaerobic respiration in mammals?

Kreb's Cycle.

And Glycolysis once for glucose, Link reaction twice for pyruvate, Kreb's cycle twice for Acetyl CoA.

Waaaaat?!??! Glycolysis happens in CYTOPLASM not matrix!!
