What are the consequences of having an electrical neuromuscular junction, there must be reasons why the nmj is chemical?

How are signals form insulin integrated with those from adrealine and contraction to regulate the breakdown or synthesis of glycogen in muscle? I know that adrenaline stimulates the conversion of ATP to cyclic AMP by activating adenyl cyclase, and I think insulin does the opposite. But how are the signals combined before having a net effect? It would be easier if they were both hormones. Is adrenaline a hormone? Because it is a neurotransmitter specifically acting on target tissues (though Wikipedia says it's a hormone as well). Is the integration of signals just a simple "summation" of the effects? But that would mean there is no integration...

Enzyme kinetics often follow both zero and first order kinetics. Zero order kinetics are followed when the substrate S has saturated the enzyme. First order kinetics are followed when the enzyme is not saturated. Why is this?

but don't you lose a lot of the accuracy if you do the transformation?

Hello there. I have just finished a biological experiment on "effect of trypsin concentration on rate of casein hydrolysis" I have already obtained a graph, and I used a program called "Graphpad Prism" to analyse the data usin nonlinear regression (3rd degree polynomial). I have got all the parameters like sy.x, degrees of freedom... But how do I use these parameters to analyse whether my results are reliable, and by varying enzyme concentration results in an increase in rate? I have also considered Spearman's rank coefficient but this is only for linear relationships. What else can I do to determine whether my results show regression?
