Sodium is not a second messenger in hormone action. Second messengers are typically small molecules or ions that transmit signals from the cell surface, where the hormone binds to its receptor, to the interior of the cell. cGMP (cyclic guanosine monophosphate), calcium ions (Ca2+), and cAMP (cyclic adenosine monophosphate) are all examples of second messengers involved in various cellular signaling pathways. Sodium is not typically considered a second messenger in hormone action.
So, the correct option is (C): Sodium
The current passing through the battery in the given circuit, is:
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
A full wave rectifier circuit with diodes (\(D_1\)) and (\(D_2\)) is shown in the figure. If input supply voltage \(V_{in} = 220 \sin(100 \pi t)\) volt, then at \(t = 15\) msec:
Biotechnology is a vast field of biology that involves the creation, production, and modification of useful products for human welfare using both the technology and the execution of living organisms and their components. An agricultural engineer, Karoly Ereky, coined the word "biotechnology" in 1919, achieving him the title of "Father of Biotechnology."
Among many, the two core techniques that entitled the birth of modern biotechnology are :
