Active Transport

Module 3, Lesson 3B

​Remember!

• ​Passive transport

  • ​Particles move from high concentration to low concentration

  • ​No energy required

​Active Transport

• ​Movement of particles from low concentration to high concentration

• ​Requires energy in the form of ATP

Multiple Select

Which statements are true about active transport? MORE THAN 1 ANSWER

• Goes from high to low concentration

• Goes from low to high concentration

• Needs energy

• Does not need energy

​ATP - Charged Molecule

• ​Adenosine triphosphate (ATP)

  • ​ATP has 3 phosphates

  • ​The 3 phosphates indicates that it is charged

  • ​To release the energy, 1 phosphate detaches, changing it to ADP (adenosine diphosphate)

​ADP - Discharged Molecule

• ​Adenosine diphosphate (ADP)

  • ​has 2 phosphates

  • ​adding another phosphate leads to energy storage

Multiple Choice

Which one is discharged? 

• ADP

• ATP

Multiple Choice

Which one is charged? 

• ADP

• ATP

Multiple Choice

Which part of ATP stores the energy? 

• Adenine

• 3 phosphates

• Ribose

​Protein Pumps

• ​Particles moved through active transport uses protein pumps

• ​ATP provides the energy to allow the protein pumps to function

Multiple Choice

What allows the protein pumps to transport particles?

• ADP

• ATP

​Bulk Transport

• ​When a large amount of particles need to be moved, using the protein pumps would take too long

• ​Bulk transport is when a large amount of particles are moved in or out of the cell

​Endocytosis vs Exocytosis

• Endocytosis

  • ​Materials are being brought into the cell

• ​Exocytosis

  • ​Materials are being brought out of a cell

Multiple Choice

Endocytosis transports materials _________ the cell

• Out of

• Into

Multiple Choice

Exocytosis transports materials _________ the cell

• Into

• Out of
