2. If E. coli is growing using NADH as its electron donor and nitrate (NO3-) as its electron acceptor during anaerobic respiration, how many NADH molecules must be oxidized to generate 20 ATP molecules

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

i guess because there isn't enough love going around. < 3

what is the question?
