The process of moving substances across the cell membrane is called "transport." This can occur through various mechanisms, including passive transport (such as diffusion and osmosis) and active transport, which requires energy to move substances against their concentration gradient. Additionally, facilitated diffusion involves specific transport proteins to help substances cross the membrane. Together, these processes maintain the cell's internal environment and enable communication and nutrient uptake.
What else can I help you with?
What is the net movement of substances to regions of lower concentration called?
This process is called diffusion. If the substance moving is water, it is called osmosis.
Does Phagocytosis move substances out of a cell?
No, phagocytosis is a process where a cell engulfs and internalizes solid particles or other cells. It is not used to move substances out of a cell but rather to bring them into the cell for processes like digestion or immune response.
Where do electrons moving across the inner membrane come from?
The electrons moving across the inner membrane in mitochondria come from the oxidation of nutrients, such as glucose, during the process of cellular respiration. These electrons pass through the electron transport chain, generating a gradient of protons across the inner membrane that is used to produce ATP through a process called oxidative phosphorylation.
What is The movement of materials around inside a cell called?
1. Passive transport processes describe substances moving from regions of higher to lower concentrations without the use of energy. This includes diffusion, which is the basic movement of substances from an area of higher to lower concentration, as well as osmosis, which is the movement of water from an area of higher to lower concentration. Facilitated diffusioninvolves the diffusion of solutes or water through channel proteins in the plasma membrane.2. Active transport processes involve the movement of solute against a gradient, meaning it moves from areas of lower to higher concentration, and requires energy in the form of ATP. Transport proteins assist in moving these substances in and out of the membrane.3. Vesicular transport involves processes that use vesicles or other bodies in the cytoplasm to move large molecules or particles across the membrane. Endocytosis involves the capture of a substance outside of the cell when the membrane engulfs it. Two of these processes are called phagocytosis, in which the membrane engulfs solid material, and pinocytosis, which involves the membrane folding inward to form a channel for liquids to enter.
What word means moving materials to the outside of a cell?
Exocytosis is the process by which cells release substances outside the cell. This involves the merging of vesicles with the cell membrane to expel the contents outside the cell.
What are the processes involved in moving substances across the cell membrane?
Diffusion
what uses vesicles to move substances out of a cell?
It is called exocytosis, which is defined as "a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane." The opposite of exocytosis is endocytosis.
What is the net movement of substances to regions of lower concentration called?
This process is called diffusion. If the substance moving is water, it is called osmosis.
What is the process called when water passes through rock or soil dissolving and removing substances?
This process is called leaching. Water passing through rock or soil can dissolve minerals and other substances, carrying them away with the moving water.
What are means of moving non-specific substances in bulk across the plasma membrane?
Endocytosis
What is the process of moving materials across membrane with energy?
active transport

Which process is responsible for involving an antiport carrier moving solutes in opposite directions across a cell membrane?
The process responsible for involving an antiport carrier moving solutes in opposite directions across a cell membrane is called countertransport. This process utilizes the energy stored in the electrochemical gradient of one solute to drive the movement of another solute in the opposite direction.
What is the process of moving particles across the plasma membrane?
well that depends on how long or tall it is!
