Active Transport

Question 0

Electrogenic pumps:

Electrochemical gradient

Answer 0

Creates and electrochemical gradient, which is a difference in charge on the two sides of the membrane

Question 1

Electrogenic pumps

Answer 1

Active transport

Transport proteins that generate voltage across a membrane

Question 2

Electrogenic pumps:

Membrane potential

Answer 2

Has potential to do

Creates Voltage, which is separation of charge

Question 3

Sodium / potassium pumps

Answer 3

Active transport

When the Na+ don’t match the K+ ion on either side.

*set up the ability to transmit electricity in heart / nerves.

Question 4

Proton pump

Answer 4

Active transport

Pumps H+ ion (proton)

Question 5

Cotransport pump

Answer 5

Active transport

Works with another single pump which has actively transported a substance across the membrane and created a gradient.

One pump is passive and provides energy to power the active one
