| Dec 14, 2014 at 13:31 | comment | added | WYSIWYG | @J_mie6 I missed it then but after a while looked at this question again. The answer to your question requires the model parameters and other reactions. Can you provide the link to the source where you read this? | |
| Jun 8, 2014 at 10:38 | comment | added | J_mie6 | @WYSIWYG that's an interesting equation, I will look into it, I love a bit of exponential decay from physics! | |
| Jun 8, 2014 at 10:36 | comment | added | J_mie6 | @MCM so, if the enzyme to convert TP into the respiratory substrates works faster than all the other enzymes, and given that Carbon Dioxide will diffuse slower in lower temperatures (hence less input), all the levels of intermediates should decrease? | |
| Jun 8, 2014 at 6:59 | comment | added | WYSIWYG | Note that reaction rates depend exponentially on temperature as per Arrhenius equation. So the change won't be linear. Moreover the activation energies for different reactions will be different. $\\k=Ae^{-E_a/{RT}} \\\frac{k_1}{k_2}=e^{-E_aR(\frac{1}{T1} - \frac{1}{T2})}\\\\$ | |
