CGU Which codon is the code for the amino acid valine (Val)?

A. GUC
B. CGU
C. UGU
D. UCG

atp is used for energy.

if you know your abc's you should be able to get your answer or just use google

i wish i could with all of them i can barley see the first one so here's the answer to the first one b

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.
