Cell Membrane Transport

The warmer it is the more fluid like it becomes

The usage of energy(ATP) to transport molecules. Usually against the concentration gradient. It uses the protein in the cell membrane to do these processes.

Transports sodium outside the cell and brings potassium into the cell. It maintains the electrical gradient.

Responsible for transporting calcium to outside the cell. Helps maintain the electrical gradient. It plays a crucial role as it helps signal the cell.

Moving hydrogen ions from low concentration to maintain the electrical gradient.

The expelling of materials. Using the secretory vesicles that is created by the Golgi apparatus. Main thing this process does is to remove the waste from the cell.

Opposite of exocytosis, difference being that it takes molecules in the cell.

It's the process where the cell membrane creates a vacuole that contains molecules that are used as food for the cell. The lysosome fuses with the vacuole to break down the food.

It's the process where the cell membrane creates a vesicle that holds solute and transports around the body.

It creates a vesicle that has receptor proteins. It imports materials around the cell.

No energy(ATP) needed, uses the moving of particles because the concentration inside the cell is lower compared to outside the cell(diffusion).

It's diffusion for molecules that can't pass through the lipid barrier because the molecules are charged, to large of a size, and has a polarity. It uses channels and pores that are created by the integral protein to help transport molecules.

Transportation of water through the cell membrane, it is the usage of concentration gradient. The moving of water to low pressure areas to high pressure areas(Inside to Outside of the cell). Only works with water, uses aquaporins(AQP) which transports water.

Solute greater inside the cell than outside

Solute greater outside the cell than inside

The cell solute is the exact same as the outside

It's the movement of a substance from an area of high concentration to an area of low concentration. It's usually goes through the lipid barrier. Transports only non charged, non polar molecules due to its amphiphilic properties of the lipid barrier. The speed that the molecules gets diffused is affected through the size(smaller the size the faster the diffusion), temperature, and the concentration gradient.

Helps to keep the fluidity of the cell

Carbohydrates are used for cell recognition. If they are on top of a lipid it creates a glycolipid and on a protein creates glycoprotein. Also known as Immune response.

Phospholipid Bilayer:

It is polar in nature and because of this it is hydrophilic, that's why it face outside of the cell

It's made of lipids and hydrophobic in nature hence why it is facing inwards

Proteins functions includes; Transporting molecules, and it's important in chemical reactions since it gives off important enzymes. Sends signals, some proteins have cell receptors to help identify/recognize cells, helps attach cells together, and lastly it's attached to cytoskeleton/extracellular matrix.

Proteins that are embedded in the cell membrane. It has both a hydrophilic area and hydrophobic area.

It's the protein that allows certain molecules to go through and spans the whole cell membrane.

It has a carbohydrate on the protein

These protein are not embedded into the cell membrane but float around it. It is entirely hydrophilic.

Only one thing is allowed to go throguh

Two things are allowed to go in the same direction

Two moloecules go in out in opposite directions

Resting becomes more positive

When it has the exact charge it needs.

Resting becomes more negative

It is open or closed and depending on the chemical that is given it is slower.

It is always open and allows specific molecules in and its always fast transport.
