Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol. There are two main ways in which molecules are transported into and out of cells - active transport and passive transport.

The following statement is true about passive transport: carrier proteins are sometimes used during passive transport.

Explanation:

There are two man ways in which molecules are transported into and out of cells; active transport and passive transport. While active transport requires an input of cellular energy, passive transport does not. In passive transport the molecules can move freely in and out of the cell, through the cell membranes, through simple processes such as diffusion or osmosis. Sometimes, when the molecules are moving too slowly, the cell uses carrier proteins as channels to help the movement along.

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.

Well i had the same answer, so the correct answer would be a. but in this case it would be the one with plasma membrane and cell wall circled that is next to the hairy pill type of thing.
