what do muscle cells during oxygen deprivation gain from the conversion of pyruvate? a. atp and lactate b. nad+ and lactate c. CO2 and lactate d. atp and alcohol e. atp, lactate and CO2 Thanks a lot guys!!
I would think it”d be (b) nad+ and lactate because when your muscles don”t have enough oxygen, then they”ll undergo anaerobic glycolysis of which lactate is the product. And this also regenerates nad+ which is needed to keep going through glycolysis to generate ATP.
You are watching: Muscle cells in oxygen deprivation convert pyruvate to
B. Glycolysis happens and the product is pyruvate. Since there is no oxygen the muscle doesn”t do the citric acid cycle and changes the pyruvate to lactate and NAD+. The NAD+ is needed to keep glycolysis going, and if I remember right the ATP produced is only during glycolysis, and not when pyruvate is converted to lactate and NAD+.
Thanks guys.. I thought there was an error in the question but it does make sense since the atp produced is not DIRECTLY due to the anaerobic process!
Sorry to revive this thread but I just took that Topscore too and I”m stumped with this one. I think the best answer would be NAD+, lactate, and ATP. Why does the answer only include NAD+ and lactate? I thought that during glycolysis, 2 ATP are created via substrate-level phosphorylation… Thanks!
oh ok I get it, thanks!…but I still think the wording is kinda tricky…when you”re under pressure you might just clump closely associated things together. But I guess that”s why we all LOVE this test so much
