Active Transport 2023

What type of transport is this?

• Endocytosis
• Facilitated Diffusion
• Active Transport Pump
• Osmosis

Active transport is movement of particles through the cell membrane from a region of ...1... to a region of ...2... using energy in the form of ...3...

• 1: lower concentration, 2: higher concentration, 3: NADPH

• 1: higher concentration, 2: lower concentration, 3: NADPH

• 1: higher concentration, 2: lower concentration, 3: ATP

• 1: lower concentration, 2: higher concentration, 3: ATP

Which one is the definition of active transport?

• movement of particles through the cell membrane from a region of lower concentration to a region of higher concentration using energy in the form of ATP.

• passage of water molecules from a region of their higher concentration to a region of their lower concentration through a partially permeable membrane

• net movement of molecule from a region of higher concentration to region of lower concentration. Molecule down a concentration gradient

• net movement of molecule from a region of lower concentration to region of higher concentration. Molecule down a concentration gradient

The picture is an example of...

• active tranport
• passive transport
• diffusion
• osmosis

Even though the concentration of salt is high in some gland cells and low in the blood, these cells can move salt out of blood and into the cells.  This is an example of

• passive transport
• active transport
• diffusion
• osmosis

The roots of a plant contain a high concentration of minerals and the soil contains a lower concentration.  The roots absorb minerals from the soil.  This is an example of

• passive transport.
• active transport.
• diffusion
• osmosis

Cells sometimes use energy to transport materials across the cell membrane.  This is called

• photosynthesis
• osmosis
• cellular respiration
• active transport

Which is an accurate description of the diagram below?

• Na+ and Amino Acids are both transporting passively.

• Na+ and Amino Acids are both transporting actively.

• Na+ is diffusing passively, and Amino Acids are transporting actively.

• Na+ is transporting actively, and Amino Acids are diffusing passively.

Solutes move against the concentration gradient

• Passive Transport
• Active Transport

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not
