The potential difference is created in a cell ........... (due to chemical reaction/using a generator)

In a chemical reaction , a catalyst used for

Action potentials are generated due to

According to this diagram , the potential difference across the terminals is ( internal resistance of cell =r)

A cell of emf E is connected across a resistance R. The potential difference between the terminals of the cell is found to be V. The internal resistance of the cell must be -

________ is neither created nor destroyed during a chemical reaction.

The rate of a chemical reaction increases by catalyst due

Mechanism of vision includes following steps in random order A. Generates action potential in ganglionic cells through the bipolar cells. B. Membrane permeabilities of rods and cones change. C. Light induces dissociation of retinal from opsin. D. Activation of photopigment of rods and cones. E. Light rays focussed on the retina. F. Potential differences generated in photoreceptor cells. G. Image formed on retina is recognized by the brain. H. Action potentials are transmitted by optic nerve to the visual cortex of brain. The correct sequence is

The steps involved in the mechanism of vision are given below. Arrange them in proper sequence and select the correct option. A. Dissociation of retinal from opsin and generation of potential difference in photoreceptor cells. B. Focusing of the light rays in visible wavelength on the corner through the lens. C. Generation of the action potential in ganglion cells through bipolar cells. D. Analysis of neural impulse and formation of aa image on the retina. E. Transmission of the action potential by the optic nerve to the visual cortex.

Action potential is generated by

The law of conservation of mass states that mass is created during a chemical reaction.
