What is passive diffusion?

• Process of molecules moving from lower to higher concentration without energy input.

• Process of molecules moving from higher to lower concentration with energy input.

• Process of molecules moving from lower to higher concentration with energy input.

• Process of molecules moving from higher to lower concentration without energy input.

What is facilitated diffusion?

• Facilitated diffusion is a type of active transport where molecules move against their concentration gradient.

• Facilitated diffusion is a type of endocytosis where molecules are engulfed by the cell membrane.

• Facilitated diffusion is a type of passive transport where molecules move across a cell membrane with the help of transport proteins.

• Facilitated diffusion is a type of osmosis where water molecules move across a cell membrane.

Which type of transport moves substances against the concentration gradient?

Which type of passive transport moves water?

• Osmosis

• Passive transport

• Facilitated diffusion

• Active transport

What is active transport?

• The movement of molecules across a cell membrane against their concentration gradient, requiring the use of energy from ATP.

• The movement of molecules across a cell membrane with their concentration gradient, requiring the use of energy from ATP.

• The movement of molecules across a cell membrane without the use of energy from ATP.

• The movement of molecules across a cell membrane with their concentration gradient, without the use of energy from ATP.

Which type of transport involves the engulfing of substances by the cell membrane to move the partical from outside the cell to the inside of the cell?

• osmosis

• diffusion

• endocytosis

• exocytosis

What is endocytosis?

• Cellular process of engulfing substances into a vesicle formed by the cell membrane.

• Cellular process of synthesizing substances within a vesicle formed by the cell membrane.

• Cellular process of breaking down substances within a vesicle formed by the cell membrane.

• Cellular process of releasing substances from a vesicle formed by the cell membrane.

Which type of transport moves substances with the help of transport proteins?

• facilitated diffusion

• active transport

• osmosis

• simple diffusion

What is exocytosis?

• Process of vesicles fusing with the cell membrane and releasing their contents inside the cell.

• Process of vesicles fusing with the cell membrane and releasing their contents outside the cell.

• Process of vesicles fusing with the cell membrane and releasing their contents into the bloodstream.

• Process of vesicles fusing with the cell membrane and releasing their contents into the nucleus.

The cell membrane is important for maintaining ____________________ because it controls what enters and leaves the cell

• cell membrane

• homeostasis

• water

• enzymes
