•If oxygen is lacking, how might cells meet their energy needs through fermentation? Explain and give some examples of cells that can do this.

Ad, if you read the site rules you would know that we are not allowed to answer homework questions. Sorry.

This is for you to answer. Tell us what you came up with, we'll help you make your answer better if possible :)

You discover a new element mimionium which has 400 protons and 401 neutrons. You predict that the atomic form of Mimionium will hav____ electrons and that the negatively charged ion will have _____ electrons

What is the property of an atom in terms of sub atomic particles? An atom is neutral, so, the number of protons is (equal to / greater than / less than) the number of electrons?

For the second one, the correct way is to go using orbitals. Have you done these yet?

Just_Another_Lemming agrees : I hope they allow you to help them work through the problems.

Yes, I'm not doing the homework of the asker, I'm guiding him/her to the answer. :) I'm trying to initiate the thinking skills, using what he/she can recall from his/her lessons.

By glycolysis.for example when you are so active that your respiratory system could not meet your oxygen need,they reach energy by glycolysis.the product of the glycolysis pathway is pyruvate.Pyruvate can be used in different mtabolic pathways.In muscle for example pyruvate at last produces lactate,wich cause feeling pain in your muscles after exercise.
I don't know if I answered you completely...
