Effect of heat on respiration in organisms

[Stef74]

Can you please explain the effect of heat on respiration in organisms. I am trying to write a report for an experiment I havent done involving a respirometer and maggots, and I am struggling to find relevant information

[MrMistery]

Cellular respiration is very much affected in all organisms. It is easiest to measure in plants. basically what you need to know is that there is a minimum, an optimal, and a maximum. At most plants the minimum is 0 celsius, optimal 30-35 celsius. Pine trees can breathe at -25 celsius. Some thermal algae at +65 celsius. The optimal temperature of 35 celsius goes for most organisms.. With a lot of exceptions..

am I correct to think respiration increases as temp does up until the maximum temperature.

The following link shows a nice little graph of how pH and temperature affect enzymatic activity.

hi u there?
hm...

the effect of heat of respiration to organism. right?
i think the heat from the respiration, maybe for us, human, it can keep our body warm. any one know that the efficiency(am i write a correct word) of respiration (aerob) is just 40%. so.. + 60% of energy that we get become calor.

then i am thinking the same answer as Mr. Mistery about enzyme. keep on fisiological homeostasis(i hope i write the correct words-homeostasis/homeotasis )

okay.. can i write more?

uh...

I can say like this (maybe it's a little bit go to the animal cells):
in animal cells, glycolysis is occured in the cytoplasm where NAD+ is reduced with 2e- and forms NADH+H. then, this NADH+H carries the H+ ions and e- to the cristae mitochondrion when ETS occured. During the carrying, NADH+H lose some of it's kinetic energy and that's why the efficiency are lowered.
Anyway, for some info (I'm sure eeryone have known 'bout this)..if the efficiency of the respiration is 100%, then our body will have exploded into pieces because fusion reaction between H+ ions and O2 as the last e- acceptor....

Are we talking about the influence of heat on respiration or the other way around?
