where is the graph
it's linked as the first thing on the question...
sorry I just saw that, but B is in fact correct :)
how do you know?
Well I know that it is not A just by looking at the graph
well, A is not correct, as heat production drops at various points while muscle tension increases
And the heat production isn't constant because it drops and raises itself.
C is incorrect because it is not constant
and it isn't C because the heat production is not constant as muscle tension increases
and D is not correct because heat production is in fact highest near the low point of muscle tension
Hope this helped :)
uh, D is arguable. heat production is low at the tail end of the cycle where the tension is also just as low as it was when the heat production was high
I think they're related in some way, but I can't find it... I mean, there's a correlation in that they both fall drastically near the end of the the chart.
I think the answer is D, that the heat production is NOT related to muscle tension, because for many values of muscle tension, we can find heat production to be high or low, depending on the time in the contraction
Hm, that does make sense. So how do you disprove B then?
look where the heat production is highest. what is the muscle tension there? now find another spot on the graph with lower muscle tension and lower heat production. if you can find one, then heat production is not the highest near the low point of muscle tension.
Oh, I totally missed the lower muscle tension point on the graph. Thanks for pointing that out or I would've gotten this wrong.
heat production is high between the spots where muscle tension is between 2 and 3 ticks on the left hand scale, right? well, if you look at the curve for muscle tension, most of the graph has lower muscle tension than that area...and the heat production is lower in that other portion of the graph, too
I think the rough mental model here is that the muscle cell contracts and does a bunch of work right away, generating heat, but it can't continue to contract with increasing tension for long, and is exhausted, and doesn't create much heat while whimpering in pain :-)
That's a good way to view it, I hadn't thought of it. Thanks for all your help :)
I hope it is correct :-) But looking at the graph, it seems hard to accept B as true...
Yeah, now that you pointed that out for me, B does look incorrect.
shoot me a message or post back here when you find out the answer, ok?
I will, definitely. It's my anatomy final so I just hope I get a good grade.
This was wrong...
