6.5 Cell Transport TFU

Front

What is a hypertonic solution?

Back

A hypertonic solution is one in which the concentration of solutes is greater than that of the cell, causing water to move out of the cell.

Front

What is active transport?

Back

Active transport is the process of moving substances into or out of a cell against their concentration gradient, requiring energy.

Front

How are blood types distinguished?

Back

Blood types are distinguished by the arrangement of carbohydrates on the plasma membrane of red blood cells.

Front

Does passive transport require energy?

Back

No, passive transport does not require energy; it occurs along the concentration gradient.

Front

What is the main component of the plasma membrane responsible for transport?

Back

Phospholipids are the main component of the plasma membrane that allows substances to move in and out of the cell.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is an isotonic solution?

Back

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

Front

What role do proteins play in the plasma membrane?

Back

Proteins in the plasma membrane facilitate transport, act as receptors, and provide structural support.

Front

What is cytosis?

Back

Cytosis is a form of active transport that involves the movement of large molecules or particles into or out of the cell via vesicles.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, potentially causing it to swell and burst.
