Cell Membrane, Transport, Hypertonic, Hypotonic, Isotonic

Front

What is equilibrium in the context of cell membranes?

Back

Equilibrium is the state when the concentration of particles inside a cell is the same as the concentration of particles outside the cell.

Front

Which molecule in the cell membrane is primarily responsible for transporting large molecules?

Back

Proteins are involved in transporting large molecules across the cell membrane.

Front

What is osmosis?

Back

Osmosis is the movement of water across a membrane.

Front

What does it mean for a membrane to be selectively permeable?

Back

A selectively permeable membrane allows some molecules to cross while others cannot.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, leading to water moving into the cell.

Front

Define isotonic solution.

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What role do proteins play in the cell membrane?

Back

Proteins facilitate the transport of substances across the cell membrane.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
