glucose

what molecule does glycolysis start with?

6

how may carbons are there at the beginning of glycolysis?

3

how many carbons are there at the end in each pyruvate compound?

pyruvic acid

what is the name of the (2) compounds produced in glycolysis?

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

how many ATP molecule are formed by the whole process of glycolysis?

2

how many ATP molecule are "lost" in the whole process?

2

what is the net yield in energy for 1 glucose molecule?
how many ATP?

glucose, glycolysis

pyruvate is the first molecule in the krebs cycle, where does it come from?

carbon dioxide, nadh

what is given off during the first two steps of the krebs cycle?

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
