Answer:yes
Explanation:
Ion pumps are assemblies of integral membrane proteins, like ion channels, that modulate ion transport into and out of a cell or organelle, leading to generation of electrical signals. Ion pumps, however, work against their concentration gradient, so require energy input, but the energy can also be derived from the concentration gradient of another ion.
Answer:
the correct sequence of the events happened during nerve impulse is (d): 2,1,4,3
Explanation:
Originally K+ ions remains inward the membranes while Na+ ions remains outward to maintain a resting potential of membrane.
Upon stimuli Sodium channels open on membrane and Na+ diffuses inward leading to the depolarization of membrane that is it becoming more positive due to Na+ and K+ ions.
To regain it polarized state or in repolarization state Potassium channels open and K+ begun to diffuse outward while Sodium channels gets closed and Na+ ions remains inside the membrane.
Potassium channels are not efficient as compared to Sodium Channels, so an excess amount of K+ion move outward so Hyperpolarization state achieved.
As the both ions are on the wrong side and will not be available for the next nerve impulse. Hence in Refractory period by the help of Na+/K+ pum, both ions move back to their original place and membrane achieve its resting membrane potential state.
The effect of <span>this to the protein is that the protein would not be made due to coding for a nonsense codon. This situation is an example of nonsense mutation. This is a mutation where a sense codon that corresponds with </span>one of the twenty-one<span> amino acids that is specified by the genetic code is altered to a chain – terminating codon. Thus, the protein will not be created.</span>
