Answers to worksheets in the Biomolecule summary notes

Today I'm actually here for half day (afternoon). I've just recovered from bronchitis.  Thanks for your patience.  Last period, you were given a worksheet on Fats, Carbohydrates and Nucleic acids. For the key, see the keywords in the Biomolecule Summary Notes.  The worksheet answers are in the sections starting on page 8. 
HW: Review the chapter and read the section on protein. Proteins and Acid/Base review will be our last topics before a comprehensive review and test coming up.  Our final lab will be on Potions, biological potions made from the buffer carbonic acid

Review DNA, RNA and ATP and do Worksheet

We'll review the lesson on DNA, RNA and ATP and you'll be doing this worksheet for homework.

Insight into the race for the Nobel Prize

This Guardian Article goes into detail about the story of the discovery of DNA.  Apparently, Franklin arrived at many of the same conclusions as Watson and Crick and while the latter duo did not technically "steal" data, (her data was available if they'd asked her directly) they did use Franklin's data in a "cavalier manner" and without proper credit.  Apparently, they would have arrived at the x-ray data earlier, had Watson bothered to pay attention during a Franklin lecture:

DNA RNA and ATP notes today

story of the discovery of DNA:  From Avery's awesome zombie apocalypse strep experiment to Watson and Crick's brilliant model making.  And don't forget Ms. Rosalind Franklin, who's groundbreaking work on X-ray diffraction on DNA crystals helped Watson and Crick crack the code.

The presentation notes today are here .  It has many details on the three kinds of nucleic acids: DNA, RNA and ATP.  We covered up to the end of DNA and will continue with the other part next day.
FYI , another summary of the discovery of DNA can be found in this link from the Nobel Prize website.

And, for those keeners amongst you, here is the ORIGINAL PAPER from "Nature".  It's super short and quite readable for a groundbreaking scientific paper that revolutionized our ideas of reproduction. They do have a small mention of Wilkin and Franklin along with other researchers at the very end of their paper.

Page 54 and 55. Know the diagrams and charts on these pages

Our lessons so far:

we are getting to the end of the unit.  So review chapter 2
bonds
water properties
Carbohydrates
Lipids
Nucleotides

and Chapter 4.2
DNA Replication

We still need to cover
Chapter 2 Proteins and amino acids

DNA Replication Song

In addition to our origami today, this is the song. Hdog is Hansel and Qdoggy dog dog is Quinton. They were Braverman's performers too.  They know me by a different name.

Big Thank you to Ms J Mergens for organizing the field trip to the Don Rix Distinguished Keynote

Genome BC welcomed our school with a sign with our school crest, gave us a personal Q and A with Dr. Budowle and regaled us with a gourmet dinner reception afterwards where we mingled with professionals in the field of forensics!  Wow.  A HUGE HEARTFELT THANK YOU TO Ms. Mergens for organizing this awesome event!!!! Our Bi 12 class is so very grateful!!

Don Rix Distinguished Lecture, photos

Apparently Sheila guessed correctly that you were all photogenic and asked if you are permitted to be photographed. Please bring ahandwritten parental note permitting photography

" We will have a photographer on site, taking photos of the talk itself and candid shots of the reception. Would be great if we could get some photos of the students. OK if I send you photo permission forms? Or was photo permission approved on the field trip permission forms that were sent out?



Thanks,



Sheila"

more questions...

number 15:  this question is about energy.  What organelle is used for energy?
mitochondria

Surface area to volume ratio:
number 58.  Remember that the cell that has the highest S.A. to Vol ratio can absorb the most nutrients
Just calculate them:
Cell A 3:1
Cell B 4:3
Cell C 3:2

If you do the calculation, then S.A /vol for Cell A is the highest at 3

Number 32 is easier if you replace the word "polypeptide" with "protein" and realize that all proteins are made by ribosome. hemogoblin, centrioles are all proteins

All lipids are made by smooth ER.
62 is an excellent organizer

Biology questions key, if there are any more questions, email me

We went over two questions in class 1.1
17:  Endomembrane system is part of the secretory process thus only secretion would be affected by a toxin.
30:  ADP is formed only when ATP is used
And ATP is used whenever energy is used
Thus only one choice uses energy. The other ones do not use energy.  Another way to ask this question is:  Which of the following processes use energy?
28.  If a channel protein or a pump stopped working, then whatever the channel might allow in would stop.  Thus amino acids would not be allowed in through the channel.

Poll results and meeting the FBI agent at the Don Rix distinguished lecture

First, your test poll.  Despite the fact that one person voted three times... this pie graph below indicates you prefer the test to be next thursday.
Next,  for those who are signed up for Oct 20,  your teachers have been given a list of your names.  They ought to give you an early dismissal at 2:45 next Tue so you can run to Nanaimo station and get to Convention Centre by, yikes, 3:30.  See if you can possibly get out prior to 2:45, in your finest, Business Casual attire.  You will be glad you dressed up a little, because Genomics BC gave us FRONT ROW SEATS so we can ask questions to the FBI agent.

Your quiz questions for next period are here and don't forget your homework is to do all the review questions for chapter 3.

Test coming up. Your review checklist. updated chapter review instructions

We are now at the end of Chapter three. We started the chapter looking at the fundamental criteria for life,  and cell organization, the definition of tissue, organ, organ system etc.

Then we took a look into the inner workings of the eukaryotic cell and its organelles.  Then we found that cells have a limit in size, due to the limitations caused by its surface area to volume ratio.   We examined Each organelle and discussed its role in the secretory process.   We briefly looked at the role of ATP generated by the mitochondria.  And we discussed how the cell transports things in and out of itself, using active and passive transport. 

YOUR STUDY CHECKLIST.  

1.  You made extensive two column notes on the fine details of chapter 3.  Use these to quiz yourself.

2.  You did your colouring in the biology colouring book: Focus on these diagrams:   The Animal Cell, The Plant Cell, Active and Passive Transport.  Know these vocab words on the diagrams.

3.  You did the Chapter Review questions at the end of Chapter 3.  DO UP TO NUMBER 62. Omit 8 and 12.  I  will look at these review questions to guide my questions for the test.

4.  You did all the labs and understand the main observations:  

a.  Lab 1  Gummi Bear lab:  Observe the effect of a hypotonic solution on Gummi Bear.  What happens to the Gummi and why.

b.  Lab 2  Sphagnum Moss lab:  Sphagnum moss is a primitive plant, a bryophyte with very thin tissue.  Observe the cell wall and vacuole under the light microscope

c.  Lab 3   Liver Anyone?   In this lab, observe the effect of the catalase enzyme from raw beef liver on a small sample of hydrogen peroxide.  Explain the function of catalase in your body.  

Lecture notes on oct9, Catalase lab

Lecture notes from Oct 7, turgor pressure, facilitated transport.

Correction: ions and amino acids use facilitated transport.  Simple diffusion is for Oxygen,  Carbon Dioxide and urea.

Biological Organization. Chapter 1

Last day, we reviewed the 8 criteria of life and also the levels of biological organization.  We have now finished Chapter 1.  Our next topic is chapter 3, The Eukaryotic Cell.  You will find the lecture notes for biological organization below:

Welcome to Biology 12

In this course we will explore the biology of the human body starting with the cell as the basic unit of life and studying how the human body maintains the biochemical processes of the cell, whether it is located in your the big toe, liver or heart.
