Active Transport Across Membranes

Question 1

What are the two main ways primary active transport takes place using ATP?

Answer 1

Question 2

What are the domains of this Ca++ ATPase? (SERCA)

Answer 2

Question 3

For P-type ATPases, what’s the general rules about them?

Answer 3

Primarily bidirectional transport of ions.
Typically used to maintain ion gradients.
Mostly controlled by phosphorylation.

Question 4

Besides SERCA, what are two other very common P-Type ATPases?

Answer 4

Question 5

Describe the mechanism of P-type ATPases.
Check marks:
Know the two main states by both name and function.
Specific amino acid involved
Domains envolved (3)

Answer 5

Question 6

Describe the mechanism of ATP dependent transport - ABC Transporters. What is the same between primary transport and ABC transport and what is different?

Answer 6

Same : both have an open state to the inside and open state to the outside, never open to both sides at once.
Different: Two states were hydrolysis and ATP binding is needed .

Question 7

Define what secondary active transport is and what are the two types of secondary active transport?
