1
how many molecule are there at the beginning of glycolysis?
2
how many molecules are there at the end?
cytoplasm
where in the cell does glycolysis occur?
2
how many ATP does it "cost" to rearrange the glucose molecule at the start of glycolysis?
glucose is oxidized
NAD+ become NADH during glycolysis. What does this imply is happening to the original glucose molecule?
4

2
how many carbons does acetyl-CoA have?
4
how many co2 molecules are given off during the krebs cycle?
pyruvic acid, glucose
where did the carbon molecules given off in the krebs cycle come from?
1
how many ATP are formed from each original pyruvate molecule in each "turn" of the krebs cycle?
2
how many ATP are formed from each original glucose molecule?
matrix
where does the krebs cycle occur in the cell?
4
how many NADH and FADH are formed from each original pyruvate molecule in each "turn" of the krebs cycle?
8
how many NADH and FADH are formed from the original glucose molecule?
ATP
