Answer:
D) Na+ is used to repolarize the membrane.
Explanation:
Option D is wrong choice because it is K+ which is used to repolarize the membrane not Na+.
As soon as membrane gets depolarized because of influx of Na+ due to opening of voltage gated Na+ channels simultaneous opening of voltage gated K+ channels and closing of Na+ voltage gated channels takes place. As a result of which K+ moves out of the cell leading to drawing of electrochemical gradient out of the cell.
In order to achieve resting membrane potential, more Na+ must be out of the cell and more K+ must be inside the cell. There are many leaky channels on neurons from which Na+ has tendency to leak into the cell while K+ has the tendency to leak outside of the cell. So Na+/K+ pump which is located on the membrane of neuron keeps pushing Na+ outside of the cell and K+ inside the cell so as to maintain resting membrane potential which is -70 mV.
Equation: sunlight + Carbon Dioxide (6CO2) + Water (6H2O) = Glucose + Oxygen
Reactants: Sunlight + Carbon Dioxide + Water
Products: Glucose and Oxygen
Allergylymphatic disorder is characterized by hypersensitivity to a foreign antigen
Acorn worms look nothing like people; the worms have no limbs and breathe through slits in their guts. But they share approximately 14,000 genes with humans, scientists found, comprising about 70 percent of the human genome
(M1xVi1)+(M2xVi2)=(M1xVf1)+(M2xVf2)
(.08x.5)+(.05x0)=(.08x-.1)+(.05xVf2)
