Which of the following most specifically explains why relay proteins only bind receptor tyrosine kinases (RTK) after activation? a. SH2 domains are only present in the relay proteins after activation
b. SH2 domains in the relay proteins only bind Tyr that has been phosphorylated in the RTK
c. SH2 domains in the relay proteins must be phosphorylated on Tyr to bind RTK
d. SH2 domains in the relay proteins only phosphorylate Tyr in the RTK after activation
e. SH2 domains in the RTK must be phosphorylated on Tyr to bind relay proteins

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
