That's what Destroyer is saying. They don't do it in the mitochondria (because they don't have it), but still....
If Destroyer says it it must be true
My guess is that the NADH produced from glycolysis only are used in the ETC.
STOP STOP STOP!!!!
keep it simple...
1) destoryer is right... no krebs in prokaryotes, BUT they can still yield 38 ATP
in prokaryotes a net total of 38 molecules of ATP are produced by cellular respiration. Most prokaryotes have very simple cells which lack several types of organelles present in eukaryotes, and therefore the Krebs Cycle and the Electron Transport Chain occur in the cytoplasm and/or using chemicals embedded in the cell membrane. In contrast, eukaryotes have more complex cells with more specialized organelles to perform given functions. In eukaryotes, the Krebs Cycle and Electron Transport Chain occur within the mitochondria, and thus the pyruvic acid resulting from glycolysis must be sent into the mitochondria for these reactions to occur. However, to move one molecule of pyruvic acid (remember each molecule of glucose turns into two pyruvic acid molecules) from the cytoplasm into a mitochondrion costs the cell one molecule of ATP (therefore two ATPs for a whole glucose), thus a net total of 36 ATP molecules per molecule of glucose is produced in eukaryotes as compared to only two in fermentation.
2) NADH is used in other things than ETC besides oxidative phosphorylation
I see, but then it has a Krebs-like cycle?
Also, Bio 133: RNA viruses are retroviruses. It is the other way around. All retroviruses are RNA viruses.
yea all retroviruses are RNA viruses bc they need reverse transcriptase

For simplicity purposes no. There are some new species of bacteria that do Krebs cycle, but not in the mitochondria. Prokaryotes do not have mitochondria.That's what Destroyer is saying. They don't do it in the mitochondria (because they don't have it), but still....
