Cell Transport

What is Homeostasis?

• A state of relatively constant internal physical and chemical conditions that an organism or cell maintains to function properly.

• A process of cellular respiration that generates energy for the cell.

• A mechanism by which organisms adapt to their environment over time.

• A type of cellular division that results in two identical daughter cells.

What are Protein Pumps?

• Transport proteins that use cellular energy to move small molecules and ions across the cell membrane against their gradient.

• Proteins that facilitate passive transport of molecules across the cell membrane without energy.

• Enzymes that break down proteins into amino acids for absorption.

• Structural proteins that provide support and shape to the cell.

Aquaporin

• Water channel proteins that facilitate the rapid passage of water molecules into or out of cells.

• Proteins that transport ions across the cell membrane.

• Enzymes that catalyze biochemical reactions in the cell.

• Structural proteins that provide support to the cell membrane.

What is Osmotic Pressure?

• The pressure exerted by a gas in a closed container.

• The force produced by the net movement of water out of or into a cell due to solute concentration differences.

• The pressure required to compress a liquid into a solid state.

• The force that drives the movement of air in and out of the lungs.

What is Active Transport?

• The movement of materials across a cell membrane against a concentration gradient, which requires the use of cellular energy.

• The passive movement of molecules from an area of high concentration to an area of low concentration without the use of energy.

• The process by which cells engulf large particles or other cells, requiring energy.

• The movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

What is Passive Transport?

• The movement of molecules across the cell membrane from a region of higher concentration to lower concentration without using cellular energy.

• The active movement of molecules against their concentration gradient using cellular energy.

• The process of molecules moving through a semi-permeable membrane with the help of transport proteins.

• The movement of water molecules across a membrane in response to solute concentration.

What is Osmosis?

• The diffusion of water molecules through a selectively permeable membrane from a high to a low water concentration area.

• The movement of solutes from a low concentration to a high concentration area.

• The process of water evaporation from a liquid to a gas.

• The transfer of energy through a medium.

What does the term Hypertonic describe?

• A solution with a lower solute concentration than the cell, causing water to move into the cell.

• A solution with an equal solute concentration as the cell, causing no net movement of water.

• A solution with a higher solute concentration than the cell, causing water to move out of the cell.

• A solution that is isotonic to the cell, resulting in cell swelling.

What is Pinocytosis?

• A type of endocytosis where a cell takes in extracellular fluid and its dissolved solutes, also known as 'cell drinking'.

• A process where cells expel waste materials.

• A method of cell division in prokaryotes.

• A mechanism for the transport of large molecules across the cell membrane.

What is Phagocytosis?

• A type of endocytosis where a cell engulfs large solid particles, such as bacteria or debris, also known as 'cell eating'.

• A process where cells release substances to the outside environment.

• A mechanism for cell division in prokaryotes.

• A method of cell communication through chemical signals.
