AI Thread Summary
Calmodulin is a crucial calcium-binding protein involved in the regulation of neurotransmitter release. Synaptotagmin is identified as the primary Ca2+ binding protein that facilitates this process. Syntaxin plays a role in the binding mechanism, but the discussion raises questions about the specific molecules involved in transporting these proteins into the presynaptic terminal. The conversation highlights the complexity of protein interactions in neurotransmitter release. Understanding these mechanisms is essential for grasping synaptic transmission dynamics.

and what is the name of the Ca2+ binding protein that is believed to underlie Ca2+ regulation of transmitter release

Ok But

does this mean that syntaxin is the protein causing the binding but what molecule does it pass through to enter the presynaptic terminal

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
