What effect would the concentration gradient have on the rate of water movement through cell membranes?
Concentration gradient is crucial to the structure of a cell. Cells need to be in an isotonic solution to survive *(unless they are specifically designed cells that are made to deal with being in a non-isotonic solution). Isotonic solution means that the concentration of solute outside the cell is equal to the inside of the cell.
The reason being isotonic with their environment is so important to a cell is because of the rules of osmosis. Cell membranes can pass water freely through specific channels that let it in and out. And, because of the rules of osmosis, water wants to be at equal concentration inside and out. The water will move accordingly to try and even out the concentrations of the intracellular environment and extracellular environment. To think of it in a simpler way, it does not want one side of a membrane to be salty and another side to be fresh, it will move so they are both at equal saltiness. Remember that the salt cant move across the membrane, so to even things out the WATER must move. (we are not always dealing with salt when we talk about osmosis, but to learn the principles, we can simplify it and think of solute concentrations in terms of salty or fresh water)
So, if a cell is put into HYPERtonic solution, where the concentration of solute outside the cell is much higher than that of inside the cell, it will shrivel. This is because water inside the cell rapidly leaves, to try and make the concentration of solutes inside and outside equal. You can remember this by remembering what happens if you drink salt water. You get dehydrated. Or, if you put a Freshwater Fish into very salty water, it will shrivel and die. This also explains why you gargle salt water when you have a sore throat- shrivel those bacteria up!
On the contrary, if you put a cell in a HYPOtonic solution, (solution where the concentration of solute is very low outside compared to the inside of the cell) the cell will blow up like a balloon. This is because water rapidly flows into the cell to try and make concentrations of solute equal inside and outside. The cells can blow up so big that they can pop, or lyse to use the proper term.

What are osmotic gradients?
When water flows from areas of high concentration to areas of low concentration through semi-permeable membranes; down it'd concentration gradient.
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.

The difference in concentration of a substance across space is called a?
The difference in concentration of a substance across space is called a concentration gradient. This gradient drives the movement of molecules from regions of higher concentration to regions of lower concentration through processes like diffusion or active transport.
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.

What kind of concentration forms whenever there is a difference in concentration between one place and another?
A gradient forms when there is a difference in concentration between two places. This gradient drives the movement of substances from areas of higher concentration to areas of lower concentration through processes such as diffusion or osmosis.
How does the movement of molecules occur down a concentration gradient?
The movement of molecules down a concentration gradient happens through a process called diffusion. This is when molecules move from an area of high concentration to an area of low concentration, driven by the natural tendency of particles to spread out evenly. This movement continues until the concentration is balanced throughout the system.
How do charged particles move across membranes?
Charged particles move across membranes through the process of facilitated diffusion or active transport. Facilitated diffusion involves the movement of particles through protein channels, while active transport requires energy to move particles against their concentration gradient.
