Summer term

First of all sorry for not using this more - definitely should have been more organised!  Here are the keypoints that everyone should be comfortable with by summer:

• What ATP is, how it is broken down and re-formed and why this happens (energy!).
• Photosynthesis (phs.) is probably the most important part of the course so far.  You need to be comfortable with the structure of the plant cell and where phs. happens, as well as the two stages (light indpeendent and light dependent).
• There are also factors that limit the rate of phs. - namely temperature, CO2 concentration and light intensity.  You should also know what the compensation point is.

• Finally, after phs. you need to have a rough idea of what happens to the glucose in both aerobic and anaerobic respiration.

Here is another diagram of the light independent scetion of phs.  Feel free to find others that make sense to you, as long as you know where the electrons come from (photolysis) and what is produced (ATP and NADPH).




This diagram shows us the light dependent section which feeds ATP and NADPH into the light independent section to produce sucrose.



Happy holidays

I hope that everyone is having a good break, I'll put some more revision stuff up here soon but in the meantime thought I'd let you know about the plan for after the break.  We'll be peer marking the mock exams we did to help familiarize ourselves with how answers should be written, and then doing some other revision stuff.  Using the papers and mark schemes here or on the AQA website would be a good way to go if you're wondering what to do. 

Revision

This is a reminder to the people who were away on Friday that we'll be having the mock Unit 2 exam in the double tomorrow morning.  No one needs to worry too much, but make sure you've been through your notes and prepared as well as you can by doing some past paper questions.   

Antibiotic resistance

This is the link to the slideshow we used on antibiotics last week: https://docs.google.com/present/edit?id=0ATFUvVu_WNI_ZGRxdDk3a3hfMTAydnRiOW1kcg&hl=en
Make sure you remember a couple of reasons why Baceria can gain resistance to Antibiotics, and how this occurs.

These are the links to the papers and mark schemes on the AQA website:

Remember that not all the organisms in this segment are Bacteria, but the ones that are need to be specially adapted to their environments.  Horizontal gene transmission helps Bacteria quickly adapt to different conditions such as these. 

Bacterial genetics

This is the link to the slideshow we used today, please email me f this one doesn't work! https://docs.google.com/present/edit?id=0ATFUvVu_WNI_ZGRxdDk3a3hfM2d2ZnR3cGQ1&hl=en&authkey=CNPV_tAN

Remember to make sure you're comfortable with how horizontal transmission occurs, and the advantages of doing so for next lesson.
