What is A cell moving particles with the use of energy is called?
Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
What is the difference between diffusion and bulk flow in terms of the movement of substances across a membrane?
Diffusion is the movement of substances from an area of high concentration to low concentration, while bulk flow is the movement of substances in a fluid due to pressure differences. Diffusion occurs passively, while bulk flow requires energy.
What is meant by bulk?
Bulk conveying systems enable the movement and handling of a large amount of products or items. Bulk conveying should allow companies to run more efficient operations.
How diffusion occurs along with convection in fluid?
Diffusion in fluid occurs when particles move from an area of high concentration to an area of low concentration due to random motion. Convection, on the other hand, involves the bulk movement of fluid resulting from temperature or density differences. In a fluid, both diffusion and convection can occur simultaneously, with diffusion driving molecular movement within the fluid while convection causes bulk movement of the fluid itself.
What is meant by bulk conveying?
Bulk conveying systems enable the movement and handling of a large amount of products or items. Bulk conveying should allow companies to run more efficient operations.
What does Bulk fluid movement typically across capillary walls?
intercellular clefts
What is the difference between bulk motion and diffusion?
The difference between the two is that bulk motion is the flow through the capillary. Diffusion is the movement of the molecules in a fluid.Ê
What is bulk transport in cells?
Bulk transport in cells is the movement of large quantities of molecules or particles across the cell membrane at once. This process helps in the efficient transport of substances such as proteins, polysaccharides, or even entire organelles. Bulk transport includes both endocytosis (taking in substances) and exocytosis (releasing substances).
What is bulk liquid of a solution called?
The bulk liquid of a solution is called the solvent. It is the component that dissolves the solute in a solution. Water is a common solvent used in many solutions.
Why is convection heat transfer caused by bulk movement of fluid particles?
Convection heat transfer occurs due to the bulk movement of fluid particles, such as air or water, which carry thermal energy from one place to another. As the fluid particles are heated, they become less dense and rise, while cooler particles sink. This movement sets up a current that transfers heat through the fluid.
What is heat transfer within a fluid?
Heat transfer within a fluid occurs through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between molecules, convection is the movement of heat through the bulk movement of fluid particles, and radiation is the transfer of heat through electromagnetic waves. These mechanisms work together in the fluid to distribute heat energy and ensure thermal equilibrium.
Breaking bulk at the wholesale level is called?
Allocating: Breaking a homogeneous supply into smaller and smaller lots ("breaking bulk")
