[doc3232]

I think 2 is a if I understand the question.
Acetylcholine is dissolved by the enzyme that break it up that has a similar name.
These questions are tough.

Nice test

 

[atlanta213]

answer???

 

[yakuza]

K since TeamGuo got them all right I'll post explanations.

1. Which catalyst becomes consumed during a reaction?
a. lipase
b. carbonic anhydrase
c. ribozyme
d. adenylate cyclase
e. none of these, enzymes do not get consumed
ribozymes are the one exception of enzymes that DO get consumed. The rest listed, obviously don't become consumed.

2. Concerning the synaptic cleft, which is false?
a. acetylecholine may taken back up into the nerve terminal after its release
b. anti-cholinesterases may cause muscle contractions to have no coordination
c. acetylcholine may be degraded by acetylcholinesterase
d. Curare may cause paralysis by blocking nerve impulses to muscles
e. all are true
This is false because. Acetylcholine can NOT be taken up into the nerve terminal, only its protein part choline can be taken back up for recycling. So, acetylecholine gets degraded by acetylecholinesterase into choline + acetyle coA. Also but may not be important, the vesicle that exited exocytosis is taken back up for recycling via endocytosis.


3. One of the major differences between fungi and bacteria is that only fungi
a. are photsynthetic
b. can produce spores
c. are always diploid
d. can undergo meiosis and mitosis
e. have a cell wall


4. All of the following are infections except
a. typhoid
b. botulism
c. common flu
d. strep throat
e. mononucleosis
Botulism is caused by a toxin, not a virus. It stops the release of acetycholine from the presynaptic membrane which means that it'll cause paralysis


5. Serum proteins are
a. albumin + fibrinogen
b. albumin + fibrin
c. globulin + fibrinogen
d. globulin + albumin
e. fibrin + globulin
These are all plasma proteins(fibrin is the actual blood clotter). BUT only globulin and albumin are SERUM proteins.
I'm not sure why fibrin isn't a serum protein, but I think it is what it is..
If you never heard of a serum protein don't worry too much, I didn't either until I got a question similar to this on a practice bio

6. Regarding melatonin, which 2 are false?
a. its lightens skin in primitive vertebrates
b. is secreted by the intermediate lobe and the pineal gland
c. is antagonistic to MSH
d. is important for the regulation of circadium rythms
e. is important for the regulation of the intermediate lobe
Melatonin is secreted by the pineal gland to regulate circadium rythms and lighten skin in primitive vertebrates. It has nothing to do with the intermediate lobe at all, so DO NOT get it mixed up with MSH of the interior pituitary.

you mean MSH from the pars intermedia of the anterior pituitary.
I am not sure if you can refer it as interior pituitary... just making sure

Sorry about that, your right. MSH is from the intermediate lobe, duno why I typed interior pit.
