    1. Dry weight of a human cell = 400g (cells are 90% water)
      Haploid human genome = 3x10^9 base pairs
      length for 10 nucleotide paris = 3.4nm
      molecular weight of ATP = 507
      Total body weight of water = 40L ( assume ATP concentraion is 3mM throughout)
      The average cell contains 3mM of ATP
      Oxidative metabolism yields 38 mol ATP per mole glucose

      How many cells are there in your body?
    2. How much DNA (in base pairs)is there in your body?
    3. What is the total length (inkm)of the DNA in your body?
    4. Estimate the mass (ingormol)of ATP in your body.
    5. What is the minimum mass of glucose (in g) that would provide enoughenergy for the synthesis (from ADP and inorganic phosphate) of all theATP in your body?
    6. How much ATP (in g) would be required to synthesise all the DNA in yourbody?

    Can somebody please help me on any of this questions or give me a starting point on how to answer them as i'm really confused?

    They're very stupid questions and you'd never get asked them on any biology tests, unless you're doing a wierd exam board, would you?
    What does ingormal mean?

Do you agree with the proposed ban on plastic straws and cotton buds?
