HELP! The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case. 1. Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.

2. The two sides of a cell membrane face different environments and carry out different functions.

3. The molecular composition of the inner and outer layers of the cell membrane is determined by genes.

4. Proteins only function on the cytoplasmic side of the cell membrane, which results in a asymmetry across the membrane.

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.
