L03 - ACTIVE TRANSPORT

Question 1

What are the 2 proteins that transport molecules via active transport in humans?

Answer 1

• ATP pump
• Coupled transporters

Question 2

How does an ATP pump work?

Answer 2

• A molecule is moved against its concentration gradient using energy from the hydrolysis of ATP

Question 3

What are the types of coupled transporters?

Answer 3

• Symporters
• Antiporters

Question 4

How does a symporter work?

Answer 4

• A molecule has an electrochemical gradient and is coupled with another molecule and also moves that molecule against its electrochemical gradient. Both molecules are moving in the same direction

Question 5

How does an antiporter work?

Answer 5

Molecule has a electrochemical gradient and is coupled with another molecule. It moves that molecule against its electrochemical gradient. Both molecules are moving in opposite directions
