Homeostasis Cell Transport

The release (exit) of large particles from the cell is

• pinocytosis

• phagocytosis

• endocytosis

• exocytosis

The movement of water across the cell membrane from areas of high concentration of water to areas of low concentration of water

• endocytosis

• osmosis

• facilitated diffusion

• pinocytosis

The type of cell transport that DOES NOT require energy

• active transport

• passive transport

The movement of molecules from an area of high concentration to areas of low concentration until equilibrium is reached.

• osmosis

• diffusion

• plasmolysis

• cytolysis

What role do protein channels play in the cell membrane?

• They provide structural support to the cell membrane.

• They facilitate the transport of specific molecules across the membrane.

• They store energy for the cell.

• They synthesize lipids for the cell membrane.

Which of the following is a type of passive transport?

• Endocytosis

• Osmosis

• Exocytosis

• Phagocytosis

Which of the following is a function of the phospholipid bilayer in the cell membrane?

• To provide energy for cellular processes

• To act as a barrier to most water-soluble substances

• To store genetic information

• To synthesize proteins

Which of the following is a characteristic of facilitated diffusion?

• It requires energy input from the cell.

• It involves the use of transport proteins.

• It moves substances against their concentration gradient.

• It only occurs in plant cells.

Which of the following is an example of active transport?

• Diffusion of oxygen into cells

• Sodium-potassium pump

• Osmosis of water

• Facilitated diffusion of glucose

Which of the following best describes the process of exocytosis?

• The cell engulfs large particles from the external environment.

• The cell releases substances to the external environment.

• The cell absorbs water through osmosis.

• The cell transports ions through protein channels.
