Cell Transport

Front

What is the function of the Carbohydrate Chain in the cell membrane?

Back

The Carbohydrate Chain is used for recognition and signaling in the cell membrane.

Front

What type of transport is EXOCYTOSIS?

Back

EXOCYTOSIS is an example of Active transport where molecules move from Low concentration to High concentration.

Front

What happens to a cell placed in a Hypertonic solution?

Back

Water rushes out of the cell, causing it to shrivel.

Front

What is Passive Transport?

Back

Passive Transport is the movement of molecules from HIGH to LOW concentrations without the use of energy.

Front

Define Cell Transport.

Back

Cell transport is the movement of materials in and out of the cell.

Front

What is the role of Membrane Proteins?

Back

Membrane Proteins assist in the transport of substances across the cell membrane and play a role in signaling.

Front

What is the difference between Active and Passive Transport?

Back

Active Transport requires energy to move substances against their concentration gradient, while Passive Transport does not require energy.

Front

What occurs during Osmosis?

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is a Hypotonic solution?

Back

A Hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to enter the cell.

Front

What is the significance of Cholesterol in the cell membrane?

Back

Cholesterol helps to maintain the fluidity and stability of the cell membrane.
