Unit 5: Energy, Exercise and Coordination




Topic 7: Run for your life

This topic is centred on the physiological adaptations that enable animals and humans, particularly sports people, to undertake strenuous exercise. It explores the links between an animal’s physiology and its performance. The topic summarises the biochemical requirements for respiration and looks at the links between homeostasis, muscle physiology and performance. It ends by looking at how medical technology is enabling more people to participate in sport, and by raising the issue as to whether the use of performance-enhancing substances by athletes can be justified.

Topic 8: Grey matter

The scene is set by considering how the working of the nervous system enables us to see. Brain imaging and the regions of the brain are considered. The topic also demonstrates how an understanding of brain structure and functioning is relevant to such issues as the response to stimuli, the development of vision and learning. It investigates how imbalances in brain chemicals may result in conditions such as Parkinson’s disease and its treatment with drugs are investigated. Students discuss the ethical issues raised by the Human Genome Project and the risks and benefits of using genetically modified organisms.

not yet !! we will discuss all the things here later !!

I think on page 9 of the article. There is a second paragraph
Another source of unique..................................................................................
vital to fish's survival.
In which there is a line. "The gene involved originally coded for
a digestive enzyme" which should not be there.

EXPLAIN the fate of lactate after a period of anaerobic respiration in animals.

EXPLAIN the fate of lactate after a period of anaerobic respiration in animals.


- After peiod of anaerobic respiration oxygen debt builds up, causing muscle cramps
- Lactate converted back to pyruvate and enters kreb's cycle for respiration
- Lactate can be converted back into glucose in liver cells where it is stored in the form of glycogen

I am not so sure so correct me if i am wrong

I did this last June... got 95% in this paper I think....

It was a dreadfully written paper but make sure you revise the mechanisms of Action Potentials, and pay loads of attention to the article too!

Are you doing this unit in Jan? Thought it was only a summer unit?

95% is amazing considering it was a badly written paper(I hated it). How did you revise for the article apart from reading it and highlighting the main topics i have no idea what to do.

Hey,

To be honest all I did for the article was just read it and highlight a couple of things.
When I read some of the questions on the actual paper about the article I panicked and got really worried as I couldn't think of the answers initially. So I went back and re-read the questions and it turned out that some of them required no knowledge about the paper - like the synoptic question from unit 1 (6BI01) which was worth 4 marks - something like "describe how the enzyme.... is formed" and you just mention the stages of making a protein.

Also some other questions were also synoptic and general biology knowledge!

Are you repeating it?

I'd imagine that this years paper the article will be different in the way that the questions asked about the article will be relevant to what's written....as opposed to quite a few questions being synoptic based...

Do we need to learn about refractory period ect... even if its not on the syllabus.
Reply 13
any one got practice questions on the article !!
Reply 14
We need to clear the concept only or learn as well? :confused:
