Happy New Year!!!!
Let's take a moment to reflect on this last year in science discoveries- link
Monday

-Remember Ch 7. Review is due Thursday BOP + Cliffs (see schedule)
-Ch. 8 due next Thursday + Cliffs
-Ch. 3- Serengeti rules- notes + quest and model- due Friday
- Ch. 1 - Serengeti Rules e.c. - due before the end of the semester
Lecture on cellular respiration

Investigation 6: cellular respiration
Answer two bullet-ed questions on page 71.
- respirometer apparatus to class
- role of KOH?
- Learning targets
- ideal gas law?
- Lab safety
- review PLF for designing an investigation
- brainstorm variables that could affect the rate of cellular respiration- develop class list
- design an investigation that is valid and reliable to investigate one of the brainstormed variables- create a PLF to communicate their investigation design
- follow steps 1-4 on pages 81&81 of the lab manual (use large respirometers)
- post materials needed to conduct their investigation.
- conduct Lab next Tuesday- PLF due BOP then- 1/carbon unit
Thursday
- Semester Final- Tuesday January 21 (90 min): Chapters 6, 7 and 8 (Big Idea 2). MC, GI, FRQ.
- Peer score Chapter 7 Review
- Student directed investigation of cellular respiration- work on investigation design- MAKE PLF- digital copy/hard copy
- Investigation team sign-up and resources needed- Google Sheet link
Friday
- Serengeti Rules: Chapter 3- 10 pts. due Friday (Dec. 10)- structured notes and chapter questions below:
- Many bacteria must be able to synthesize the tryptophan amino acid for survival. In 1953, Jacques Monod showed how tryptophan synthesis is regulated in bacteria when he discovered the tryptophan operon. The tryptophan operon is composed of the genetic sequence that codes for an enzyme called tryptophan synthetase. Tryptophan synthetase catalyzes the final two steps of the pathway responsible for tryptophan synthesis. Upstream of this tryptophan operon is the gene that codes for a protein that represses the tryptophan operon and its ability to catalyze tryptophan. However, the repressor is unable to function unless it has the amino acid tryptophan bound to it!
- Turn to pages 56 and 57 of The Serengeti Rules. Here Sean Carroll describes a critical Nature of Science moment in the career of Jacques Monod.
a. Describe the observation Monod made as a result of his experiment, which is illustrated by Figure 3.2.
b. Write the hypothesis Monod proposed to explain his observation.
c. Briefly outline the method Monod designed to test his hypothesis.
d. Write the prediction Monod made for what he expected to see if his hypothesis was supported. - e.Using a model similar to those found on page 68 of The Serengeti Rules,show how the tryptophan operon regulatory system works.
f. Using Figure 3.6 on page 70 for inspiration, construct a model for how tryptophan regulates its own synthesis.
