I need a lot of help with a study guide for my Biology class, I have until tomorrow to figure out what I have missing. Please!

Question

@speraticdownpour $sure, ~Where~should~we~start~with~?$

anonymous · Answer

I figured out that catalysts increase the rate of a reaction by decreasing the amount of energy needed to get a reaction started. However it then asks  "what controls the type of reaction that the enzymes can help speed up?"

Hmm..  An alteration of   enzymes productivity would be:usually at extreme temperature (out of it's optimum range), as well as changes in pH, chemical presence (toxins) amount of substrate or concentration. of enzymes in a solution.
Also,note that these enzymes could help to speed up a reaction in a cell/chemical reaction by lowering the activation energy needed, to produce a reaction each enzyme act with only one substance/substrate like a lock and key. This is what is meant that they are specific for one reaction.

That makes sense, thank you! Nice to meet you too c: 

So this would also be what would influence how the enzyme's work/function. So then 
What happens to the enzyme to make it not function correctly anymore?

*Also, I gave you another medal from my other account and if you'd like me to post a new question after this one so I can give you two more medals I can do that too, I appreciate the help.(:*

@speraticdownpour Thanks, I appreciate your views But instead of medal, i prefer if you could  promise me, that, you will learn it well and do good in your exams ?

Yes of course! My questions are for use of a study guide. This is for a consultation with my virtual teacher to help me with my biology end of course exam, I assure you it is not an assignment to be turned in, just looking for some extra understandings!
