The intrinsic properties of the hydrophilic/hydrophobic/hydrophilic double layer of the membrane gives it support, due to the hydrophobic effect.

What will happen inside a visking tube if you add saliva?

If you add saliva inside a Visking tube, the enzymes in the saliva will begin to break down larger molecules present in the solution into smaller molecules. These smaller molecules will be able to pass through the selectively permeable membrane of the Visking tube, while larger molecules will be left behind, resulting in a process similar to digestion.


How do small molecules pass through the cell membrane?

There are three types of transport for molecules across the cell membrane. 1 - Diffusion - Molecules move from an area of high concentration to an area of low concentration 2 - Osmosis - same idea as diffusion, but refers to the movement of WATER across a selectively permeable membrane. How can you change water concentration? Add a solute. If you have 2 250 ml beakers, connected and divided by a selectively permeable membrane, and one beaker contains a salt solution, the salt solution is "hypotonic" (hypo- less, tonic - water) to the water filled beaker. One will see a migration of water into the salt solution beaker. BOTH diffusion and osmosis rely on concentration gradients to perform their jobs. They always want "equilibrium" between both sides of the membrane. 3 - Active transport - Proteins embedded in the cell membrane move large molecules through the cell membrane or AGAINST the concentration gradient. The size one is obvious; If it's really big, it won't permeate the membrane. As for the concentration gradient, this means that it moves a molecule INTO the area with and already HIGHER concentration. If this happens with say... H+ molecules, it creates a potential difference - ie - Voltage across the membrane. Cellular respiration counts on this process to create ATP/Energy for the cell.


What phase of matter comes after gases if you add energy?

If you add energy to gases, they can transition into a plasma phase. Plasmas are ionized gases that consist of positively charged ions and free electrons. This phase is characterized by high energy and high temperature.

Are a cell membrane's chemicals locked into place?

Any biological cell membrane or plasma membrane is made up of phospholipid bi-layer, cholesterol, small amounts of glycolipids and specialized proteins. Some components can move little bit around their position but others such as cholesterol add to the rigidity of the membrane. Lipid rafts are also immovable regions of the membrane.

Are phospholipid molecules found in the cell membrane?

Yes. A specific example, peanuts are considered Brain Food because they contain phospholipids, and this indicates that phospholipids are needed for healthy brain cell membrane function. Anyone with more polish to add to this?


How do you deconstruct Ionized Plasma to its gas form?

Add electrons.


What phase of matter comes after gasses if you add energy?

If you add energy to gas, the next phase that you get is called plasma. In a plasma, the atoms have broken apart, and you have a mixture of sub-atomic particles that are not organized into atoms. Plasma is the highest energy phase; even if you keep adding energy, all you will get is hotter plasma.


What is the function of the cholesterol molecules shown in transparency?

When you hear the word cholesterol, the first thing you probably think of is that it is bad. However, cholesterol is actually a very important component of cell membranes. Cholesterol molecules are made up of four rings of hydrogen and carbon atoms. They are hydrophobic and are found among the hydrophobic tails in the lipid bi-layer. Cholesterol molecules are important for maintaining the consistency of the cell membrane. They strengthen the membrane by preventing some small molecules from crossing it. Cholesterol molecules also keep the phosphoric tails from coming into contact and solidifying. This ensures that the cell membrane stays fluid and flexiblePLEASE ADD MORE


What does ATP synthase use to add phosphate to ADP?

ATP synthase uses the proton gradient created by the electron transport chain to drive the formation of ATP from ADP and inorganic phosphate. This process occurs in the inner mitochondrial membrane in eukaryotic cells and the plasma membrane in prokaryotic cells.


How could plasma become a gas?

The simple way to convert compressed gas to plasma is by heating it or by electrifying it. A plasma is atoms from which electrons are stripped, and anything can be converted to plasma by ripping off its electrons. By superheating gas to give the electrons so much energy that they leave the atoms, or by applying high voltage to tear electrons from atoms, the gas can be converted to a plasma.


Example of plasma?

Plasma is even on earth. Examples are the northern lights, lightning,and core,or magma. Plasma is also in neon light tubes like for advertising. Just to add plasma is also in stars, the sun, and black holes.


What if you add thermal energy to plasma?

Adding thermal energy to plasma will increase the kinetic energy of the particles within the plasma, causing them to move faster and collide more frequently. This can lead to increased ionization and excitation of the particles, generating a more energetic and hotter plasma.
