influence of temperature on biomolecules

... and information flow (lipid assembly, channels, pumps, receptors) 2) diffusion rate (interaction with molecule size and shape) 3) protein-protein interactions (again, affected also by shape/bi-stability) 4) transcription rate and errors (TF to DNA binding rate, polymerase binding rate, chromatin ...

Re: Enzymes and activation energy.

... more or less reactive. Changing local electron density directly affects reaction mechanisms, which are for the most part driven by electronic interactions (though other factors, such as kinetic energy and entropy change, also play a role). Take a look at the "Visualizing surface potentials" ...

Greenies Realise

... the release of methane in the atmosphere (methane has a shorter life span than CO2 but is also a better GHG) so not so yeahhh. Complicated interactions, and not making the predictions any easier.

The Immune System - Recognition in innate immunity. How?

... (each cell and its daughter cells of a given cell type have similar antigen recognizing receptor and specificity). It also involves more cell-cell interactions and use of co-receptors. Thus, the adaptive response is slower, but very specific, recognizing mostly protein or peptide motifs. Thus, ...
