What are the steps of anaerobic cellular respiration?
Gylcolysis takes place in the cytosol of the cell. Krebs and the
ECT are located in the mitochondria.
First you have glycolysis
That has 10 steps with many rxns but the products is 4 ATP and 2
NADH, but you use 2 ATP so your net is 2ATP and 2NADH
Next is Krebs, Citric Cycle, or tricarboxlic cycle(same cycle
different names).
That cycle has a lot of steps and enezymes involved also, but it
produces NADH, FADH2, CO2 and GTP(another form of ATP, guanine is
made instead of adenine).
Next the high energy carriers, NADH and FADH2 are carried to the
ETC, electron transport chain. There, the electrons of the NADH and
FADH2 are pumped down the ETC. As that happens protons from the
NADH and FADH2 are pumped out of the mitochondrial matrix. This
creates a proton gradient which powers the most important membrane
protein to man...the ATPase or ATP synthase. The protons flow down
their electrochemical gradient through the ATPase. When that
happens the head of the ATPase spins and attaches a free phosphate
to ADP making ATP. This is called phosphrylation. The ADP is
phophrylated to ATP. Lastly the electrons from the ETC hooks up
with O2 to make H2O. This last steps produces +/- 32 ATP's
