Title: Activity ahead of course: Active transport
Course: Biochemistry > Section: Week 8 - Unit 3_2: Membrane Transport Mechanism

Purpose

To explore the mechanisms of active transport between the extracellular fluid and the cytoplasm.

Over to you

In this video short video, there is an animated explanation of the exchange of sodium and potassium ions between the extracellular fluid and the cytoplasm.

Watch the video. Then watch it again, making the notes suggested in the activity.

Be certain to note anything that you don’t understand.

Activity:

As you watch this animation, make notes of

- The role of the Sodium-Potassium exchange pump (Na+K+ATPases pump)

Think about: what makes this an example of Active Transport (compared with the passive transport we have been studying?)

Bring your notes to class so that you can participate in the conversation about active transport across the cell membrane
