What’s the name of the structural carbohydrate that is found in plant cell wall?

The main one would be cellulose...but there is also hemicellulose and in some there is pectin.

majorly cellulose, hemicellulose and pectins are the carbohydrates which are found.

Hope it will be enough to understand, if you want more info than ask here.

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.
