What is the process that forces molecules through membranes?
I don't think that question has one answer, considering how vast the field molecular science is and there are many things to consider, but I think what your looking for is "osmosis". The process in which a solvent (generally water) moves through a mostly permeable membrane (permeable to the solvent not to the solute) from a high solute concentration to a low solute concentration without energy inputs of any kind separating two solutions of different concentrates. hope this helps.
What are the two forces that combine to produce an electrochemical gradient?
The two forces that combine to produce an electrochemical gradient are the concentration gradient, which is the difference in ion concentration across a membrane, and the electrostatic gradient, which is the difference in charge across a membrane. Together, these forces drive the movement of ions across the membrane.
Which process describes the pushing of water across the capillary (blood vessel) membrane?
The process that describes the pushing of water across the capillary membrane is called filtration. Filtration occurs due to the pressure difference between the blood inside the capillary (hydrostatic pressure) and the surrounding tissue (osmotic pressure). This pressure gradient forces water and small solutes to move out of the capillary into the surrounding tissue.
The movement of fluids between cellular compartments involves?
The movement of fluids between cellular compartments involves active transport mechanisms, such as ion pumps and channels, as well as passive transport mechanisms like diffusion and osmosis. Cells need to regulate the movement of fluids to maintain homeostasis and ensure proper function. This movement is crucial for distributing nutrients and signaling molecules, removing waste products, and maintaining proper cellular function.
How are passive bloodstains created?
Passive bloodstains are created when blood is deposited on a surface without the influence of external forces, such as gravity or blunt force trauma. This can occur when a person is bleeding or dripping blood from a wound onto a surface or when blood is transferred through contact with an object.

What is the transport is it when the blood pressure forces some water and solute particles from a blood vessel and into the kidneys?
Filtration is when fluids and solutes flow down their pressure gradient across a membrane such as in the glomerulus of the kidney.
What is the sum of the electrical and chemical forces acting on an ion is known as it?
The sum of the electrical and chemical forces acting on an ion is known as the electrochemical force. This force drives the movement of ions across a membrane or through a solution. It is crucial for processes such as ion transport and nerve signaling.
When hydrostatic pressure forces water across a membrane passively the process is called?
It's called Filtration
Types of bulk transport in cell?
Bulk transport is in 2 forms, exocytosis and endocytosis. Each of these 2 forms can then be sub divided into phagocytosis (movement of solids) and pinocytosis (movement of liquids) When bulk transport occurs, a phospholipid bilayer membrane merges with the cell membrane, and forces the contents of the vesicle in.out of the cell.
What forces a cell membrane to cell walls?
i think it is the nucleus that forces the cell membrane to cell walls.
What is the Difference between membrane potential and equilibrium potential?
Equilibrium potential is referring to the equilibrium (or balance) established between the forces of diffusion and electrical forces specific to each ion. For example, the equilibrium potential for Potassium, K+, in a cell with a semi permeable membrane is -80mV or Ek+=80mV. The membrane potential, on the other hand, refers to the voltage across the membrane at anytime and takes into account a range of equilibrium potentials such as Potassium, Sodium etc.
What is the electrochemical gradient of an ion?
spatial variation of both electrical potential and chemical concentration across a membrane. Both components are often due to ion gradients, particularly proton gradients, and the result can be a type of potential energy available for work in a cell
Where do ions diffuse across membrane to specific ion channels?
Ions diffuse across the membrane through specific ion channels that are embedded in the cell membrane. These ion channels are selective, allowing only specific ions to pass through based on size, charge, and other factors. The movement of ions through these channels is facilitated by a combination of concentration gradients and electrochemical forces.
When would cells need energy to move particles across a membrane?
Active transport over a membrane is called active because it requires conformal changes of the proteins involved, provided whatever you want to bring across is not hydrophobic enough to simply dissociate over the membrane. There are different types of carriers in biological membranes. The non-active ones are constantly open pores (for water, for example), which require no energy to stay open. However, the other methods of providing movement across the membrane come as either pores that can change their state from closed to open, or as carriers or pumps which actively transport a substance across the membrane by allowing it to attach to them (or diffuse close to them) and then changing their conformation to wield the substance to the other side of the membrane (or to open a pore). Usually, the carrier or pump is in its normal conformation in the first place because of electric and covalent forces that keep it in this functional shape. To change and wield or pump a substance across the membrane (or to open a pore), these forces need to be overcome. That requires energy (usually provided by splitting phosphate off an ATP molecule). Some carriers also simply need the energy to get back into their original shape (if the substance that attaches to them adds different chemical forces to the original carrier that already suffice to cause a conformational change).
What are the forces at equilibrium potential?
At equilibrium potential, the forces on an ion are balanced, meaning there is no net movement of ions across the membrane. The electrical force due to the membrane potential balances the chemical force due to the concentration gradient, resulting in equilibrium. This can be seen in action for ions like potassium (K+) at its equilibrium potential in a resting neuron.
