    Does anyone know what the mark scheme answer for the meaning of ''myogenic'' is?

    I know it's that the heart contracts by itself without outside stimulation, but often with these definitions they want it worded in a particular way
    If it's two marks:
    Heart beats on its own (1 mark)
    Autonomously from the nervous system (1 mark)

    Unit 5: Energy, Exercise and Coordination


    This unit is worth 40% of your A2 grade and 20% of your total A Level grade.

    Content summary:
    • *ATP, glycolysis, anaerobic/aerobic respiration
      *control and functioning of heart; ventilation and cardiac output
      *homeostasis
      *the nervous system
      *impact of exercise on body, and improving performance
      *hormonal coordination
      *brain structure and development
      *imbalances in brain chemicals
      *Human Genome Project.


    Assessment:
    This unit is assessed by means of a written examination paper, which lasts 1 hour 30 minutes.

    Assessment information
    Assessment information
    [u]This unit is assessed by means of a written examination paper,which carries 90 marks, lasts 1 hour 30 minutes and will include:[u]
    • *objective questions
      *structured questions
      *short-answer questions
      >and will also cover:
      *How Science Works
      *practical-related questions.


    One question will relate to a previously released scientific article that students will have studied during the course. Students may be asked to summarise the information in the article, and explain or comment upon the biology and other issues within the context of the article. The article may draw on knowledge and understanding from any of the four units 1, 2, 4 and 5. A different article will be provided each year and the examination questions will change to reflect this. This question carries a third of the marks of this unit.

    Unit Description
    Unit Description:
    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.


    Resources:
    Specification
    Sample Paper , Scientific Article for Sample Paper
    6BI04+5 Notes
    Scientific Article for June 2010
    Old SNAB Unit 6 Article Past Paper Pack



    Let us use this thread to discuss preparations & difficult problems and to analyse the scientific article. We can formulate glossaries and possible questions from the article and we can summarise important data as well.

    Good luck guys! Let the discussion begin! :eek3:

    i've got a question here that i hope someone can help me!!

    paragraph 7 and 8, page 7 of the scientific article

    can someone explain to me about this:-

    the last sentence in paragraph 7 says 'knock out either and muscle wasting all but stops'.. does this means that when you knock out the genes, muscle wasting do not stop?

    and in paragraph 8, 'when Glass knocked out each of the 2 atrogenes in rats, he found they suffered less atrophy after both disuse and disease'

    i thought paragraph 7 implies that if you knock out the genes, you will suffer atrophy but then paragraph 8 seems to imply that when the genes are knocked out, there is less atrophy..

    hope someone can help me! thank a lot!!!!
