Creationism

"We must concede that there are presently no detailed Darwinian accounts of the evolution of any biochemical or cellular system, only a variety of wishful speculations." --Franklin M. Harold, The Way of the Cell: Molecules, Organisms and the Order of Life, p. 205 (Oxford University Press, 2001).

Notes ATP (adenosine triphosphate) - arguably the second in importance only to DNA

As far as known, all organisms from the simplest bacteria to humans use ATP as their primary energy currency. See ATP: The Perfect Energy Currency for the Cell

  • Are there any organisms that do not use ATP?. Simple answer: ATP is the main energy carrier in all organisms. Some organisms also use GTP to great extent, but there really is not an organism that doesn't use either ATP or GTP ultimately. You use over 50kg ATP a day! In addition, NAD+ and NADPH are used for reductive/oxidative power, but are not direct energy carriers.
  • How did life exist before ATP? Notes: There is no other known energy sources other than GTP which needs ATP to be created.
  • How was ATP produced outside the highly complex mechanism currently understood? Notes: Protein parts and enzymes are used to produce ATP, but it requires ATP produce the protein part and enzymes in the first place!
  • ATP is produced by only four basic methods: (1) in bacterial cell walls, (2) in the cytoplasm of by photosynthesis, (3) in chloroplasts, and (4) in mitochondria.
