List the 6 levels of organization and define each

Molecule - they have a wide range of sizes and structures and perform a vast array of functions.

cell - consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids

tissue - an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function

population - same species that live in a particular geographic area at the same time

organ system - organs that work together as a biological system to perform one or more functions

ecosystem - community of living organisms in conjunction with the nonliving components of their environment

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.
