- 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?
- How much DNA (in base pairs)is there in your body?
- What is the total length (inkm)of the DNA in your body?
- Estimate the mass (ingormol)of ATP in your body.
- 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?
- 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?
