Active transport is when a protein moves a certain material across the membrane from a region of lower concentration to a region of higher concentration. This means the substance is absorbed against the concentration gradient and energy is needed for this active transport to work. The energy is usually comes from adenosine triphosphate or ATP, every cell supplies its own ATP by cell respiration. Globular proteins or pump proteins or transporter proteins in membranes carry out the active transport, the membrane must contain a lot of these proteins so that the cell can control the contents of its cytoplasm precisely. An example of active transport is in human nerve cells where potassium ions are pumped in and sodium ions are constantly transported out of the cell by active transport into the external fluid bathing the cell to build up a store of potential energy or an electrical impulse that is used to transmit a nerve impulse.
Exocytosis is an active process in cellular transport.
Active transport is the process that requires the use of energy to move materials across a membrane. This process involves the movement of molecules against their concentration gradient, requiring energy input from the cell.
Yes, the process of transport, whether passive or active, requires energy.
Specifically Diffusion, but it is also active transport
Active transport is an endergonic process, meaning it requires energy input to move molecules against their concentration gradient.
It has is in the name. Active Transport
it is an active transport process
Exocytosis is an active process in cellular transport.
Active transport requires energy.
Active Transport is carried out in our body cells. Active Transport uses energy to transport materials.
Active transport is the process that requires the use of energy to move materials across a membrane. This process involves the movement of molecules against their concentration gradient, requiring energy input from the cell.
Active Transport..........
a houseplant in dry soil is this process diffusion,osmosis,or active transport
Yes, the process of transport, whether passive or active, requires energy.
Specifically Diffusion, but it is also active transport
Active transport
active transport is an energy reqiuring process in which transport proteins bind with particles and move them through a cell membrane
