What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What type of transport requires energy to move molecules from an area with low concentration to an area of high concentration?
Active transport is needed to move molecules from an area of low concentration to an area of higher concentration against their concentration gradient. ATP is used as the power source.
Is a carrier protein an active transport or a passive transport?
They are used in both, in passive the molecules move in , then change the shape then leave and the entering and leaving are both by diffusion. in active transport molecules move in by diffusion, change the shape of the carrier protein, then because theyre moving into the cell where the molecule is in higher concentration energy is required to push the molecules out of the carrier proteins, this energy comes from ATP which is supplied to the carrier proteins.
What are three ways molecules move through a semipermeable membrane?
Diffusion, Osmosis and Active Transport
What process transports particles that move through cell membrane between phospholipid molecules?
Osmosis, Passive Transport, and Active Transport
When engery is required from a cell to move molecules across the cell membrane it is called?
It is called active transport.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
Does active transport result in an even distribution of molecules?
No. Active transport uses energy to transport specific molecules against a concentration gradient. Passive transport will result in an even distribution of molecules because they allow molecules to move down a concentration gradient.
How is active transport diffrent from osmosis?
Active transport occurs when molecules are moved from an area of low concentration to an area of high concentration. The cell membrane acts as a semi-permeable barrier during the process. Energy is required for active transport. Osmosis is a type of passive transport. Passive transport is similar to active transport except it requires no energy and molecules move from an area of high concentration to an area of low concentration. Osmosis occurs only if the molecules moving across the cell membrane are WATER molecules.
What type of transport is it when gluclose molecules move into a cell?
passive. any transport that is diffusion to get into a cell is passive.
In what ways do molecules move?
it moves by diffusion, osmosis and active transport
What particles move through cell membrane between phospholipid molecules What transport?

Which process uses proteins to move molecules against a concentration gradients?
active transport
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
