Chapter 14 Active transport

Question 1

Primary active transport

Answer 1

requires ATP

transports ions such as Na+, K+, Ca+, H+, and Cl-

Question 2

secondary active transport

Answer 2

Co-transport (symporter)=glucose, amino acids

counter transport (antiporter)= Ca+, H+

Question 3

P-Class ATP pump

Answer 3

Ions (Na+, K+, H+, Ca+)

Question 4

F-class

Answer 4

protons (H+)

Question 5

V-class

Answer 5

protons again but in lysosomes

Question 6

ABC-class

Answer 6

Ions, drugs, and xenobiotics

Question 7

Sodium-potassium pump

Answer 7

3 binding sites for K+ inside

2 binding sites on outside

ATP is utilized and causes conformational change

Na+ pumped out,K+ pumped in

Question 8

Calcium pumps

Answer 8

intracellular Ca+ is low

2 pumps per cell-1 in cell membrane to pump out, 1 in ER to pump in

Question 9

Hydrogen Pumps

Answer 9

in parietal cells to help form HCl

in renal tubules secretes H+ from blood into urine

Question 10

Symporters

Answer 10

move molecules in same direction

1st molecule moved with gradient

2nd molecule moved against

Question 11

antiporters

Answer 11

moves molecules in opposite direction

1st molecule move with gradient

2nd molecule inactively moved against gradient
