B) plant cells are heterotrophic, while fungal cells are autotrophic. C) plant cell walls contain cellulose, while fungal cell walls contain chitin.

a. the production of carbon dioxide through the process of photosynthesis

not only is it colder, it also becomes darker, less salty, and more dense.

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.
