Yes, bulk flow requires energy as it involves the movement of substances in bulk, such as fluids or gases, from an area of higher pressure to an area of lower pressure. This movement is driven by the pressure difference, which requires energy to overcome resistance and move substances through a system or medium.
Exocytosis=) need more? i'll be glad to help! just add Dylan Wilkerson on facebook!=)
The kidneys are responsible for filtering blood, regulating fluid balance, and removing waste products from the body. These activities require a lot of energy to maintain, as the kidneys need to continuously work to perform these essential functions. Additionally, the kidneys have a high blood flow rate, which also contributes to their energy demands.
Simple diffusion = flow of small molecules ALONG the concentration gradient, does NOT require energy. facilitated diffusion = flow of molecules ALONG the concentration gradient with help of CARRIER PROTIENS or CHANNELS, does NOT require energy active transport= flow of larger or charged molecules AGAINST their concentration gradient, REQUIRES input of ENERGY in the form of ATP.)
Non-living things do not require energy as they do not have processes that need to be sustained or powered. Examples include rocks, water, and air.
No, facilitated diffusion does not require the cell to use energy. It is a passive process where molecules move across the cell membrane with the help of transport proteins.
Yes, energy can flow on its own through various processes such as conduction, convection, and radiation. These processes do not require external forces to initiate the flow of energy.
Yes, pumps require energy to operate. They use mechanical energy to move fluids from one place to another, such as water in a pumping system or air in a compressor. The amount of energy needed depends on factors such as the flow rate and pressure required by the pump.

Pressure gradients drive bulk flow by creating a difference in pressure between two points, causing the movement of fluids from high pressure to low pressure areas. The greater the pressure gradient, the faster the bulk flow of fluids will occur.
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
The bulk flow of filtrate is a type of diffusion. Diffusion is a broad category of distribution of a substance within another substance. Diffusion can be specific or general in location and rate of flow.
Pressure Gradient
if there is convective flow or bulk flow or random mixing of molecules ,eddy diffusion will occur.
no it does not require energy.
Convection is the mode of heat transfer, referring to the transfer of heat energy due to bulk motion of a fluid."Convection current" is the name of that bulk motion of the fluid, the transfer of MASS. I prefer to call it buoyantly driven flow. It doesn't flow due to convection, convection is due to if flowing. It flows due to buoyancy in the case of free convection.Peyton
Endocytosis is the bulk transport of materials into a cell, using energy in the form of ATP. It is an active process, and the energy is used to move the membranes around the materials to form the vesicles that are needed, and to move the vesicles into the cell.
Energy flow refers to the transfer of physical energy from one place to another. This often involves the flow of fluid.
