Loving Those Biomolecules!

Today in class students had a chance to ask questions about the 4 types of Biomolecules and then were given a 10 question pop(ish) quiz.  This grade will be going in the assessments category and will seem to be weighted heavily until some more grades are entered in that category.  Following the quiz I went over the four levels of protein structure.  Good diagrams supporting this material can be found on pages 82-83 of your textbook.  I also recommend checking out Activity: Protein Structure under Concept 5.4 of the textbook website. 

HOMEWORK DUE ON BLOCK DAY

Read pages 150-157 for background information on Enzymes.   That is sections 8.4 and 8.5 if you are using the electronic version of the textbook!  You should know the following information when you are done:

• definition of catalyst, substrate, active site, induced fit
• what is meant by activation energy
• how enzymes lower the activation energy barrier
• the induced fit model of enzyme activity
• limits to rate of enzyme activity
• the roles of cofactors, inhibitors, pH and temperature on enzyme activity
• how enzyme activity is naturally regulated through allosteric processes and feedback inhibition

Then on the textbook website complete the investigation in 8.4 "How is the Rate of Enzyme Catalysis Measured?"  Read through the three pages of information and then open the questions on the bottom half of the screen.  Once you have answered the questions fully choose "Submit Answers for Grading."

See you on block day!
