question that im not quite getting ..lol.. i understand cellular transport and the 5 mechanisms..

however help

Cellular transport influence nearly all the the processes in the body. WHat situation in the body might occur to influence each of the 5 transport mechanisms. How might the body respond to each situation.?

Does this mean to say something that might affect each .. seperately

or something affecting all 5 at once..?

I'm replying to bump this post up the line, but I don't have a clue as to what the answer would be.

[Megsd, BSN, RN]

If I had to make a wild guess, I'd say they mean the 5 separately, because the second half of the question asks how the body would react to "each" situation (which means to me that there is more than one situation).

I don't remember a darn thing about cellular transport, so I can't help you with what situation(s) they're looking for, but that's my guess on how to interpret the question.

k i will try it with all..

I was thinking Death would affect all 5

[EricJRN, MSN, RN]

I'd agree with Megsd that they're looking for each one done separately, because of the 'each.'

Im sorry, I finished that course 5 years ago and I just don't remember. I am replying in hopes that a student taking A+P will see this and answer you. Good luck getting your answer.

thanks.. . k so now to think what would affect each stage lol

Consider that you are dealing with both active (energy dependent) and passive cellular transport mechanisms. Then also remember that enzymes and catalyst can have an affect on the rate of cellular transport. Finally, remember that passive mechanisms are greatly affected by the following:

1. Temperature--higher temp usually increases rate

2. Concentration-- higher concentration in extracellular space can increase rate of transport into the membrane.

3. Size of the molecules vs. the size of the channels in the plasma membrane.

Even after death, some passive transport mechanism are still at work until the cell walls breakdown from decay. Perhaps completely freezing an organzism would stop all cellular transport.

Perhaps greatly decreasing extracellular concentration by overhydrating could do some real damage, even cause the cell walls to swell up and burst due to osmosis.

thank you thank you .. i thought that it made sense
