What directly causes action potential?

What directly causes action potential? An action potential is caused by either threshold or suprathreshold stimuli upon a neuron. It consists of four phases; hypopolarization, depolarization, overshoot, and repolarization. An action potential propagates along the cell membrane of an axon until it reaches the terminal button. Which part of motor neuron has lowest threshold? axon […]

Which orbitals Cannot form a pi bond?

Which orbitals Cannot form a pi bond? dx2−y2+py sideways overlapping does not form π-bond as the two orbitals do not have proper orientation for the overlap. Was this answer helpful? Can pi bonds be formed in absence of sigma bonds? Yes, there exists pi bonds without coexisting sigma bonds. Here both the bonds of the […]

Is n3 Isoelectronic?

Is n3 Isoelectronic? Atoms and ions that have the same electron configuration are said to be isoelectronic. Examples of isoelectronic species are N3–, O2–, F–, Ne, Na+, Mg2+, and Al3+ (1s22s22p6). Is Ca2+ Isoelectronic with AR? For atoms/ions: For example, the K+ ion is isoelectronic with argon. Therefore, K+ and Ar are said to be […]
