What type of transport is used to move lactose into the cell?
Active transport
What proteins are used in active and passive transport?
cell membrane
What method is often used by cells to move large solid material into the cell?
active transport
What kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
What is the active transport and passive transport?
Active transport is the movement of a substance across a cell membrane against its concentration gradient and Passive transport means moving biochemicals and other atomic or molecular substances across membranes.
What type of transport is used to move lactose into the cell?
Active transport
What are 2 situations which active transport would be required?
well if the active transport was not used it would have to use the passive transport. the meaning of not using the active transport because if you use the active transport in one case it would burst
What means of particle transport requires input of energy in a cell?
Active transport is the term used to define the means of particle transport that requires input of energy from the cell. The opposite of this would be passive transport.
What proteins are used in active and passive transport?
cell membrane
What proteins are used in both active and passive transport?
cell membrane
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
What are the two general types of transport used by cells to transport materials in and out of the cell?
Active transport and passive transport.
What is the source of the energy used in active transport?
The source of the energy used in active transport is the electrochemical gradient. Another possible source of energy for active transport is the breakdown of ATP molecules.
A cell must expend energy to transport substances using?
Active transport is the type of transport where a cell must expend energy. These are endocytosis, exocytosis, and the sodium-potassium pump.
What molecule supplies the energy for active transport?
ATP supplies the energy for active transport.
What is a type of active transport used by an amoeba?
how does the ameba transport the food and other materials to all th parts of the cell
What is a molecule used by glucose as a piggyback into and out of the cell in the process of active transport?
The glucose transporter is a membrane bound protein that binds to glucose and mediates it's transport into or out of the cell.
