Answer #1

Propionate ------> Propionyl-COA ------> D-methylmalonyl-Co-A ------> L-methylmalonyl-CoA ------> Succinyl-CoA

Two ATP are required to convert propionate to succinyl-CoA.

One molecule of succinyl-CoA produces 1 GTP, 1 FADH2, and 1 NADH molecules.

So,

Number of ATP equivalents produced = 1 + 1.5 + 2.5 = 5

Net production of ATP equivalents = 5 - 2 = 3

How many grams of ATP are needed to prepare 0.24 L of a 271.0 mM solution? The anhydrous molecular weight of ATP is 478.2 g/mole, the ATP powder being used has 1.0 moles of water and 2.0 moles of Na+ per mole. I understand that i'd have to multiply the volume and the M (converting it to M from mM) to get the moles of ATP. Then i was told to use the moles to multiply it with the molecular...
