Active Transport

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...

• lower concentration, higher concentration, NADPH

• higher concentration, lower concentration, NADPH

• higher concentration, lower concentration, ATP

• lower concentration, higher concentration, 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

Transport that moves materials against the concentration gradient is said to be

(a)  

In which type of transport do molecules move against their concentration gradient?

• Passive transport

• Facilitated diffusion

• Active transport

• Osmosis

Active transport of solutes across the cell membrane requires​ (a)   because molecules are moved against the ​ (b)   , meaning from​ (c)   concentration . For example, when mangrove trees use salt ​ (d)   to secrete salt from their roots.

• energy

• glands

• low to high

Which of the following is true of active transport? (Select all that apply.)

• Requires energy

• Only involves the movement of gasses

• Low to High Concentration

• Diffusion is an example
