How is a eukaryotic cell different from a prokaryotic cell? Prokaryotic cells are only found in animals while eukaryotic cells are found in plants.
Eukaryotic cells have chloroplasts while prokaryotic cells do not have chloroplasts
Eukaryotic cells have a nucleus while prokaryotic cells do not have a nucleus.
Eukaryotic cells have more mitochondria than prokaryotic cells.

C. Eukaryotic cells have a nucleus while Prokaryotic cells do not have a nucleus

Explanation:

Eukaryotic cells have nucleus but prokaryotic cells dont but prokaryotic cells do have nucleoids that hold genetic material.

your answer should be c) enjoy!

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.
