Help please! Which is the correct biochemical sequence in the pathway for synthesis of the amino acid arginine?

a) ornithine is converted to arginine, which is then converted to citrulline

b-) citrulline is converted to arginine, which is then converted to ornithine

c-) arginine is converted to citrulline, which is then converted to ornithine

d-) ornithine is converted to citrulline, which is then converted to arginine

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

diaria maybe go see a doctor about that

answerca air mass;
