Check Answer

Answer 1

To compare cellular respiration with lactic acid fermentation based on the options provided:

A. **Both use enzymes from the mitochondria.**
This is not correct for lactic acid fermentation, as it occurs in the cytoplasm, not in the mitochondria.

B. **Both produce equal amounts of ATP.**
This is incorrect. Cellular respiration produces much more ATP (approximately 36-38 ATP per glucose) compared to lactic acid fermentation, which produces only 2 ATP per glucose.

C. **Both use NAD+ electron carrier molecules.**
This is correct. Both processes utilize NAD+ as an electron carrier, but they differ in their overall processes and outcomes.

D. **Both release carbon dioxide.**
This is incorrect. Cellular respiration releases carbon dioxide as a byproduct, while lactic acid fermentation does not produce carbon dioxide; instead, it produces lactic acid.

The best answer is **C. Both use NAD+ electron carrier molecules.**
