~Review of the class~

1) Protein catalysts

2)Catalyst: Speeds up or slows down the rate of the reaction.

3)Enzyme Action:
     -Substrates-molecules to bond
     -Enzyme-protein that facilitates bonding between substrates.
     -Enzymes are NOT changed, so they can facilitate many substrate bondings

4)The effect of enzymes on activation energy: The enzyme reduces the activation energy required for substrate bonding.

~Thoughts/Opinions~

-It was actually interesting to start learning about the digestion system, it's important to learn about and have an understanding of how it's important to be healthy.

~Above and Beyond~

Lexie Nylund, November Double Bio monday 16th

What we Learned

• Read and understand lab pg 195
• Pigment Lab
• Looked at notes he gave us (photosynthesis notes)

What we looked at

 

• The cycles of photosynthesis
• Calvin benson cycle
• The phases of the calvin benson cycle

 

What i thought

 

• I thought the photosynthesis was one of the hardest unites and should of had more time.
• The cycles were interesting to see how the calvin cyle and how everything fit in place and how it goes into G3P into glucose to starch and sucrose

 

Above and Beyond

 

• The Calvin-Benson cycle can be constructed step by step. To do so, the required energetic or reduction quivalents (ATP or NADPH) must be dragged to the reaction vector and the correct enzymes for the next reaction step must be chosen.

•  Phase 1: carbon fixation
• Phase 2: reduction
• Phase 3: Regeneration of CO2 acceptor (RuBP)

November 24th. Stephen Carrier 2/3

What We Did Today - Hand in homework (Introduction questions to new unit)
- Did notes on Carbohydrates, Lipids & Protiens
- Learned about Hydrolisis.  (Breaking Down Carbohydrates Using Water.

My Thoughts On The Class
- I thought that most of the stuff we did in class a review from Science 10. For instance we learned that proteins were composed of amino acids last year.  Some new stuff to me was learning about Hydrolisis and Dehydration Synthesis.  Though the learning about trans fats was interesting because I have always wondered what wascausing all the fuss with food companies and people when they are buying food.  Also learning about metabolism was informative as people always talk about it but never really explain what it actually is, I intrigued by that part of our class.

What We Did That Day 3/3
- went over the products of the Calvin Cycle
- learned that PGAL is the same as G3P
- learned the 3 phases of the Calvin Cylce: Carbon Fixation, Reduction, Regeneration of CO2 Acceptor
- learned that G3P is used to make carbohydrates such a glucose

My Thoughts On The Class
- the Calvin Cycle is pretty complex and a really important part of photosynthesis
- it's interesting that one cycle requires light while the other one can continue without
- in my opinion, it might have been easier for me to learn about photosynthesis if we'd learned about it first
  instead of cellular respiration

Above And Beyond

- above, a diagram of CR

- above, a diagram of photosynthesis

- put these two above diagrams together and you have the two most important cycles in life

- here is a link explaining about G3P and the other names it can go by: http://en.wikipedia.org/wiki/G3P

What We Did Today

• Wrote cellular respiration test
• Went over notes on photosynthesis
• Learned about photosystems and the electromagnetic spectrum
• Reviewed chloroplasts from grade 10

My Thoughts

• I learned a lot about photosythesis, which part of the reaction requires light, that there are two different photosystems on the thylakoid membrane and each absorbs a different wavelenght of light.
• Like cellular respiration, photosynthesis is really hard to learn solely through notes.
• That photosynthesis also produces ATP, in much the same way as CR. I thought PS was for making glucose for CR to burn, and I guess it is, but it makes some of it's own energy.

Above and Beyond

• One of the questions we began the year with was how does photosynthesis use light? In class we discussed that the light excites an electron to jump an energy level, but that seems like we have to take it on faith, as does a lot of these processes. The method we learn seems to ignore parts of the process (understandable, as they are hard enough as is)
• To remedy this lack of knowledge I went to my dad's old university textbook. After fifteen minutes of staring blankly at a page depicting chloropyll A I have decided ignorance is a lot simpler.
• I learned which energy levels each pigment in a leaf absorbs, which is as follows;

• Chlorophyll A - occurs in all green plants - Absorbs red and violet-blue light
• Chlorophyll B - Green plants, not red or blue-green algae - Absorbs red and violet-blue light
• Chlorophyll C - Brown algae and diatoms - Absorbs red and violet-blue light
• Chlorophyll D - Red algae - Absorbs red and violet-blue light
• Protochlorophyll - Etiolated plants - Near red and blue-violet
• Bacteriochlophyll - Purple bacteria -   "       "     "      "  -  "
• Bacterioviridin - Green sulfur bacteria - "      "     "      "  -  "
• Phycocyanin - Blue green or red algae - Orange red
• Phycoerythrin - Blue green or red algae - Green
• Carotenoids - Most plants, bacteria - Blue, blue-green

Sorry, I can't get a picture for this entry because I'm on dial-up and something is wrong with my computer (random freezes and resets, etc)

What we did today:
-Watched a DVD called Energy In/Out
-Practiced questions-independently, on pg 232 # 1-18 for practice on our quiz which is on thursday (ticket to test)
-looked for you tube videos demonstrating cellular respiration

My Thoughts on the Material:
- it was mainly just review, so it was fairly easy to understand
-we also have pg's 222#1-3, 226 #6 and the questions Creatine Phosphate, what is it and how does it relate to CR. How does H2S and cyanide affect CR, How might TUMS help an athelete? due tommorow
- the movie was pretty much just review on CR, the stages and what allows a plant to create CR

Above and Beyond:

- here is a very simple diagram of Cellular respiration incase your still are not getting it
- the stages of Cellular Respiration are

1. Glycolosis- occurs in the cytoplasm
2. Puruvate oxidation-occurs in the mitochondrial matrix
3. Kreb's Cycle-occurs in the mitochondrial matrix
4. Electron Transport Chain-occurs in the inner membrane

Dale Day November 9/ 2009 2/3

in the first block  we did a quiz on celular respiration that I though t was ok but I would have liked to learn the percentage of ATP created through aerobic and anaerobic systems.
In the second block  we did an experiment. it was about trying to show the Electron Transport chain. I think that it was a little confusing even with mrs.Foot's help. Next time I think that Mr. Challoner should be here when we do the next experiment on Cellular Respiration.

Todays Blog By Shannon Eslinger
 
Reminders:
-Don't forget blog
-Cellular Respiration Quiz Thursday, November 5, 2009
-Cellular Respiration Test on Friday
-Cellular Respiration Test Tuesday, November 10, 2009
-U2 Tests

What we did today:
 1) Recap
-Mark unit exam (hand in ticket to the test: Perception Sheets)
- 4 stages of cellular respiration/ location
- Oxidation/ Reduction/ Phosphoylation... the last one was really messy on the board so it was hard to copy
- "NADH has reducing power" (what does this mean?)

**Don't forget to pick up the hand-outs that you have missed**

2) Sources of Energy for Cellular Respiration

3) ATP

4) Cellular Respiration Notes (which we finished)

My Thoughts of the MATERIAL

Well I thought that today was very difficult understanding all the different methods of learning NADH. It was the same material don't get me wrong but it was just repetitive. Kreb's Cycle is very easy everyone! It is just the over-all method of going from glycolysis to pyruvate oxidation to Kreb's Cycle to Electron Transport Chain (ETC) was difficult.
Too many questions were asked today! Like what is the formula for cellular respiration... well we should all know that by now! C6 H12 O6 + 6O2 -----> 6CO2 + 6H20 + 36ATP
How does your body use proteins? Hormones, enzymes, structural components.
What do you need ATP for? Look at Pg.206 of the textbook at a very good diagram of the different uses of ATP!
