a series of metabolic steps that convert 4.__ into pyruvate, producing a bit of ATP and

If enough oxygen is available, pyruvate is transported into the 6. (an organelle in eukaryotes) and attached to coenzyme A.
This reaction produces more NADH. What is now acetyl CoA enters the Citric acid, or 7.. cycle. This is a catabolic pathway,
involving numerous enzymes that break off one carbon atom at a time from what was once glucose. As this cycle progresses
gas is released, a bit of ATP is produced, and high energy electrons are picked up by molecules of NADH and
This process is a cycle because oxaloacetate is regenerated in order to continue accepting molecules of acetyl CoA. At this point
in cellular respiration, only about 4 net ATP have been generated. Most of the
that was once in the original glucose
molecule is in the high energy.
