Module 2: Active Transport

Question 1

What is active transport

Answer 1

movement of molecules against their concentration gradient, it requires energy (ATP)

Question 2

What are the 4 types of active transport

Answer 2

1. Primary active transport
2. Secondary active transport
3. Endocytosis
4. Exocytosis

Question 3

What is primary active transport

Answer 3

ATP is used directly to transport substances against their concentration gradient, the pumps act as a carrier and enzyme

Question 4

What is secondary active transport

Answer 4

movement against the concentration gradient powered by an electrochemical gradient that was previously created by primary active transport

Question 5

What is endocytosis

Answer 5

molecules in the extracellular fluid are brought into the cell via the formation of an endosome

Question 6

What is exocytosis

Answer 6

molecules are packaged into secretory vesicles inside the cell and then released into the extracellular fluid
