What is the special function of gap junctions?
Both allow for the movement of materials between cells.
What structural feature of cells can allow molecules to flow directly from the inside of one cell to the inside of the next?
These cells have ionic channels that allow for flow of ions between cells.
What is slit junction?
it is a large fenestrations in the endothelial cells that allow drugs to exchange freely between blood and interstitium , it is found in the Liver for example
What types of membrane allow solvent molecules to pass through but do not allow solute molecules to pass through?
A membrane that does not allow substances through is impermeable. One that allows some substances, but not others, is semipermeable or selectively permeable.
Are desmosomes found in plants or animals?
Desmosomes are a type of intercellular junction in animal cells that function as a rivet.
What does movement of molecules in a liquid allow the liquid to do?
Flow
What are hollow cylinders of protein that allow for the communication between cells and involved in a gap junction?
connexons
How do you increase or decrease the movment of molecules?
Molecules react to thermal energy, or heat, as well as pressure. When you increase the temperature of molecules, they will increase their vibration and movement. Pressure can also allow molecules to move from one area to another.
How do molecules get in and out of cell?
polar molecules are repelled by the cells electrical charge.
What condition will allow water to evaporate?
The continuous movement of water molecules can lead some molecules at the surface to escape in the atmosphere as a gas. High temperature and low pressure favors evaporation.
What three methods allow exchange of molecules between cells and their surroundings?
Diffusion- Osmosis Endocytosis
Why is cellular energy vital in maintaining an organism life processes?
Like in physics, things don't just move by no reason. There has to be an energy or force to allow movement. This movement is needed to deliver oxygen, breathe, regulate temperature, etc. The ATP molecules supply these movement and thus allow life processes to go on.
What membranes allow some materials to pass while constraining the movement of other molecules.?
Semi permeable membranes as the plasma membranes in cells of our body.
What types of bonds allow different water molecules to be attracted to one another and allows capillary action to occur?
These are hydrogen bonds between water molecules.
Allows convection and can be a good conductor of heat?
What is the functions of gap junction?
They allow the propagation of electrical impulses across the myocardium. They are responsible for electrochemical and metabolic coupling. They allow action potentials to spread between cardic cells by permitting the passage of ions between cells, producing depolarization of the heart muscle.
What is the difference between a fixed and a floating bearing?
floating bearing allows axial movement of the shaft. fixed bearing does not allow for axial movement of the shaft
