is Glycolysis anaerobic or aerobic

Answer 10

Anaerobic (no oxygen)

Question 11

in the Preparatory stage, what is oxidized?

Answer 11

Pyruvates (loss of electrons)
2 carbons released as CO2

Question 12

this ends up in what part of the cell?

Answer 12

the mitochondria

Question 13

where are the energy electrons stored?

Answer 13

The NADH

Question 14

where is the citric acid cycle located?

Question 15

what is produced in this process?

Answer 15

FADH2 NADH and ATP

Question 16

how many times does this cycle happen and why?

Answer 16

happens 2 times because of pyruvates
