Any help would be greatly appreciated 
Forgot my notes and text at school, and i need these done asap!
1. Describe 3 cellular processes which make use of vesicles.
2. Describe 2 ways in which enzymes are used during DNA replication.
3. Two digestive enzymes produced by 2 different glands act on the same substance. Both enzymes function optimally at pH of 7.1 to 8.4.
a) Describe the similarity of the enzymes structures and explain why this affects their ability to act in the same substance.
b) What would happen to the rate of the reaction above if the pH was changed to 3.0?
4. Describe 2 digestive reactions which occur as a result of pancreatic secretions.
5. Describe the events that lead to inhalation after stimulation by the respiratory system.
I’ve tried looking them up on the computer but havent come up with answers for all of them..
Im NOT looking for some stranger to do my homework for me, these questions are just the ones im most stuck on. I do have answers for them but my answers either seem too short or I’m not 100% sure.
& this is extra work I’m putting in.
1. Endocytosis, exocytosis, and transport.
2. DNA helicase unwinds the strand to be replicated
DNA ligase reattaches the newly copied strands
3. b) The reaction would be slowed or non-existent because extreme pH denatures enzymes.
Hope this helps

You have a whole Internet at your disposal. Wikipedia is a good source, and many biology textbooks have online versions. This looks like a review for a midterm- if so, and you’re taking a biology course that covers this much material in a semester (perhaps honors, AP, or IB?), you should be able to answer these questions, at least basically, without a book or notes. If you really can’t and are too lazy to use the internet, you shouldn’t be in a class like that.
And you really shouldn’t be asking people on the internet to do your homework for you. It’s meant to help you, not random strangers.
