Answer #1

Answer ----- (B) if channel is the right answer.

Ivabradine is the drug which is used to reduce the heart rate in the case of the symptomatic case of the angina pectoris and the symptomatic case of the chronic heart failure.

They use to inhibit selectively the funny channel pacemaker current in the SA node and lowers the heart rate and they use to increase blood flow to the myocardium.

Some calcium channels blockers and also beta blockers are also seen to decrease the heart rate and do this work but they show more adverse effect than the ivabradine.

So the ivabradine is the drug launched by the FDI in 2005 for specifically this work.

While k channel and cl channels blockers are other drug which acts in the other coronary artery diseases and tha atherosclerosis etc.

Good wishes , do rate and comment for any doubt...

The K+-channel is very selective for K+ and efficient in the transporting speed. What structural feature most successfully explains these two functional characteristics of the channel? Select one: a. The selectivity channel is just wide enough for K+ ion so that no other ions can go in. b.

An ion-channel is a transmembrane protein that can be in one of two states: OPEN (which allows ions to pass through the membrane) and CLOSED (which does not permit ions to pass through). You have an ion-channel in which the energy of the open state is 600 cal mol-1, the energy of the closed state is 1800 cal mol-1, and the temperature of the system is 300 K. (one cal per mole is equal to 4.18 J per mole, or...
