Continue with enzymes and pre-lab for digestive enzyme processes

Daily Questions from Wednesday were based around your notes on enzymes and their functions.  All of these were sample questions from the keystone exam.

Wednesday September 26th 

Which statement explains why large changes in pH can affect the functions of plant enzymes?

1.  Large changes in pH increase the rate of cellular chemical reaction.

2.  Large changes in pH provide the energy necessary to activate an enzyme

3.  Large changes in pH can denature an enzyme causing a change in its shape.

4.  Large changes in pH can cause an enzyme to react with a different substrate.

Z could be replaced with either pH or Temperature.
Both of these effect enzyme activity.

Molecule c would most likely be the substrate of this enzyme

 We continued the notes on enzymes yesterday and finished with how temperature effects enzyme function.  We then did some pre-lab work on digestive enzymes and today actually went through the lab.  This was the first time I had you guys actually READ through a lab and do it all yourself.  It was a BIT chaotic, and only one beaker was broken (my fault) but we were able to at least get the procedures done.  Once I have all the pics and we get final results I will post everything that happened during the lab.

NO DAILY QUESTION QUIZ TOMORROW!!!!!!! We will just continue to work through this lab!!
