A particular species has three homologous pairs. One is metacentric, one is acrocentric and one is telocentric. Below, please draw the chromosomes of one cell of this species during the following three divisional phases. Explain why these three metaphases are different. What is the role each plays in mitosis and each division of meiosis? A. Metaphase of MitosisB. Metaphase of Meiosis IC. Metaphase of Meiosis II

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.
