8. what's the waste product of electrons and pyruvate combining in fermentation? a. sulfuric acid b. oxalic acid c. citric acid d. lactic acid

Lactic acid

Explanation:

Fermentation may be defined as the breakdown of glucose molecule in the limited supply of oxygen with the help of microorganisms.

Pyruvate molecules and electrons waste product combine together in fermentation to yield lactic acid and two molecules of ATP. The transfer of electron from NADH to pyruvate molecule generates the lactic acid.

Thus, the correct answer is option (D).

D. Lactic acid

Explanation:

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
