1) What is the name of peroxisomes in the early germinating seeds of plants?
a) mesosomes
b) lysosomes
c) peroxisomes
d) glyoxysomes [Too much for DAT?]

2) What is the function of the peroxisomes in early germinating seeds of plants?
a) break down fatty acids to help generate energy for growth [Nice question, but I think this is too much for DAT]
b) break down H202 [I assume it is the same as the funtion in animal cells]
c) break down amino acids for energy
d) break down toxins

3) Which protein structure is key in globular proteins?
a) quaternary
b) tertiary
c) secondary
d) primary

4) Which protein structure is key in fibrous proteins?
a) secondary [Changed my answer. This makes more sene]
b) primary
c) tertiary [wrong]
d) quaternary

5) What type of bond is associated with secondary protein formation?
a) hydrogen
b) peptide bond
c) disulfide note: disulfide bonds are important in tertiary structures.
d) ionic
Protein stucture is a very important topic to know for DAT. thanks for bringing this up.


6) In plasmodesma, a desmotubule is made from what organelle?
a) SER
b) RER
c) Golgi body
d) lysosome

Questions 3 and 4 are tought to say. Primary structure is usually the most important, because any change in one or few aminoacids will mess up everything. But then, I know the question is not looking for 'primary structure' as the answer.

Good test man. Some tough questions that I can learn from. Hope I did well.

OsimDDS, why are you going to dental school? You should just make a dental school test book! J/k man. Keep it up. You make me want to post my own test.

desmotubules are proteins. SER does not make proteins. RER is the correct answer as Osim pointed out.

as are connexins in desmosomes that block cytoplasm inflow from cell to cell...

I thought desmosomes are just for keeping the cells together. They are not passages for material to block or support any flow. It's not in contrast with what you said, OSIM, but still I did not get the point of blocking cytoplasm inflow from cell to cell. Can you elaborate?

By the way, if a question asks, "what cell junctions are damaged in blisters, the correct answer is DESMOSOMES". Keep this in mind

are questions like 1 2 and 6 really going to be on the dat? I really haven't covered those topics to that much detail...

What do you guys think?

Nah, not very possible to see those ones on DAT. Don't freak out!
