I am having trouble answering these questions, and I really need some help!

1.. How is Oxygen important to the release of energy?

2.. What is the difference in energy release between starting the metabolic pathway with glucose as compared to glucose obtained from starch?

3. How many ATP are produced for every glucose molecule that undergoes fermentation?

4. How many ATP are produced for every glucose molecule that undergoes complete aerobic breakdown?

Any help would be greatly appreciated, even if it's pointing me in the direction on where to find the answers(in layman's terms)!

I am not a kid, btw, I am an adult, who really needs help :)

Thanks!!

I wrote down in my notes or biology that adrenaline is a protein. If it is a protein then it can't be a part of endocrine signaling which involves hormone. Protein can't enter the plasma membrane like steroid hormone. So is adrenaline made in the pituitary gland? and is it a protein or steroid?

I'm doing a presentation Monday and I don't think I have enough stuff to talk for enough time.. I need some unique attributes of a Euglena! (ex. 'Can use photosynthesis as well as ingest food'). Please help, I'm having trouble finding them. List as many as you can!!

I do not want very detailed things, like it's length/speed. Just blunt facts like "Euglena has a contractile vacuole which prevents the cell from bursting." (Thanks Chez for your answer but I need less precise facts). So if anyone knows, I need to know:

1) Unique Parts
2) Unique functions/attributes.

Thanks in advance.

Ahh. I hear from my teacher that sea turtles need fresh water. I put in an assignment that how they get fresh water is by extracting the salt out of salt water and essentially crying it out.
This is what she said:

Your answer to #5 is close, but the freshwater doesn't come from the salt water they drink but from another source they ingest.

__________

Does this mean it comes from it's food?

Wells or something? Check it out in Yahoo news. What a joke LOL ROF
