Question

Anaerobic respiration produces _________ in muscle cells during anaerobic respiration.

water, energy and carbon dioxide
water, ethanol and energy (answer) am I correct?
lactic acid and energy
lactic acid and water

Can anyone check if I am correct , and if I am not please do not give me the answer but explain it to me , and let me do it on my own. Thanks !

Answer 1

If the question was anaerobic respiration in yeast then you would be correct.
None the less we are now in muscles cells which don't produce ethanol, but instead another chemical which causes the pain in your muscles during hard exercises (the lack of air)

Answer 2

Well then the answer would have been either lactic acid and water / lactic acid an energy , and i know that in Anaerobic respiration it does produce much energy , so then its most likely ( lactic acid and water ) ? @Frostbite

Answer 3

Well... you just said that anaerobic respiration does produce energy, but still you choose to say lactic acid and water?

Answer 4

But lactic acid is correct yes. but water vs energy (ATP) is the question. :) try argue for your answer.

Answer 5

(Use your knowledge about the glycolysis)

Answer 6

well water because , as i said Anaerobic respiration does not produce " much" energy so its not as useful . since it produces very litter energy , i think ? ha ha ha 0.o @Frostbite

Answer 7

Haha well it is actually true. I was being a little mean... there is in fact being product BOTH energy (ATP) and water in same ratio.

But I would personally say " lactic acid and energy" cause it is important to note the cells are not dying while doing this.

Answer 8

The water comes from dehydration of 2-phosphoglycerate to phosphoenolpyruvate and this reaction occurs twice due to the 2x 3-carbon products formed earlier in the reaction.
The two ATP then comes from the 2x 2 substrate-level phosphorylations.

Answer 9

Attached is found the "Cori cycle" which is where the important energy concept comes into the picture of the question.
