Three ways to count the ATP

Books count the ATP of one glucose in different ways. You will write a function that counts it for any values of the carriers, and compare it with fermentation.

The idea. For one glucose there are 4 ATP made directly, 2 NADH of glycolysis, 8 NADH of the matrix and 2 FADH2.

Your tasks.

1. Finish total_atp. It takes the ATP for each cytoplasmic NADH, for each matrix NADH and for each FADH2.
2. Set ncert to the total with 2, 3 and 2, and newer to the total with 1.5, 2.5 and 1.5.
3. Finish extra. It gives how many more ATP glucose glucose molecules give when respired completely, with a total of total ATP each, than when fermented with 2 ATP each.
