Good one.More please.I liked the first one.These are type of Qs we can see on DAT.

Good one.More please.I liked the first one.These are type of Qs we can see on DAT.

Glycogen, I was confused about 5 too. I know what paracrine is, but I don't have any detailed background about cytokinnies and prostaglandins. All I know is that C is all hormones which don't act in a paracrine manner. Nitric Oxide is a hormone too. I guess A should be paracrine molecules. When are we gonna get the answers?
I just googled Nitric oxide and found out that it has some paracrine functions too. growth factors are paracrine too. I think the right answer is D [a and b]

Hey Guys nice job so far Ill post the answers within the hour sorry harrygt gana let people have a shot for a few more mins

No prob buddy. Keep it up. These were some nice questions relative to the level of DAT. Where did you get them from?

 

[Orgodox]

Thanks I appreciate that. I remembered that I collected a bunch of old questions my teacher asked in previous years and collection from other sources from my intro class that I kept on word and saved what I thought were hard ones. Then last night I looked at them and posted some relevant ones for the DAT.
As for the I II III type I also hate them because you can know 2 or 3 things and be unsure of one detail and get NO credit at all. They stink. I have a few more really good questions that are DAT style and make you think a little I will try and post them early next week.

 

[Orgodox]

The answers are
1 a
2 e
3 c
4 c
5 d
6 d
Great job guys!!

[DRHOYA]

Ahhh crap..1 wrong. Can you explain how Nitric Oxide answers correctly?? Since it is a gas, couldn't it just diffuse freely and have many effects in the body?

Nice test btw.
