In this video we look at the mechanisms of calcium extrusion from cells, namely the PMCA (Plasma membrane associated calcium ATPase) and the Sodium Calcium Exchanger (NCX).
You said the release rate of PMCA is 150/s, but it should depend also on the Calcium concentration as the rate should have units of 'per Molar per second'. Is the 150/s the value for [Ca]=100nM in steady state conditions?
Hello, first of all thank you for your video. I'd like to point out that the PMCA pump extrudes 1Ca++ in exchange of 1H+, needing one ATP to make the exchange. You forgot to mention the H+ :) (I'm a med student and we saw that in class).
It's so perfect!! Thanks 💕💕💕
thanks for the great video!
Very well explained - thank you!
Great explaination

NCX is 1 Ca2+
Ich glaube dass, NCX nur ein Ca entlaesst.
