Which of the following correctly compares fermentation and cellular respiration?
Both provide ATP molecules, but only fermentation occurs when oxygen is present.
Both result in substantial ATP molecules and lactic acid production.
Cellular respiration produces more ATP molecules than fermentation.
Cellular respiration provides ATP molecules at a slower rate than fermentation.

Have you read your material properly? These are direct questions. I strongly suggest you got through your material again.

I just didn't understand them.

Let's go through your options and see if I can help.  Humans can use both cellular respiration and fermentation (specifically lactic acid fermentation).  Our bodies essentially only use fermentation in muscles when then get over used and can get oxygen from the blood fast enough (or in enough quantity) to perform cellular respiration.

That should help for a bit more as well.  If our muscles only use fermentation as a last resort when there isn't enough oxygen, then what does that tell us? It should tell you at least to things.

Answer these questions for me: What does it mean that we can perform both, and in our bodies in different places, both at the same time?

What does it imply that our bodies use fermentation only if there isn't enough oxygen for cellular respiration.
