Answer:
Option b. by binding Ca++ when the cytosolic concentration is greater than 500 nM.
Calmodulin gets activated only after binding with Ca++ when the cytosolic concentration is greater than 500 nM (generally in the range of 500-1000 nM).
Add Answer to:
How is calmodulin activated? A. by binding both calcium and potassium B. by binding Ca2+ when...

Pu010 2. You are studying a bacterial protein, Pmp 7, that pumps one potassium (Kt) ion into the cell for each calcium ion (Ca²+) that is moved out of the cell. Pmp 7 uses energy from light to pump these ions across the membrane. Experiment 1: You make an artificial membrane vesicle that has Pmp7 as the only protein on the membrane. Pmp 7 is orientated on this artificial membrane vesicle as it is oriented in a bacterial cell, and...

Question 1 (1 point) Vasoconstriction occurs when epinephrine (adrenaline) binds to the a-adrenergic receptor on vascular smooth muscle cells. One way to treat high blood pressure is to administer competitive inhibitors that bind to this receptor. The Kd for binding of epinephrine to this receptor is ~UM. Based on the measured affinity (Kd) of the following drugs for the a-adrenergic receptor, which might be good candidates for high blood pressure medication? Drug A: Kd = 0.6 M; Drug B: Kd...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
