In the dark, photoreceptor rods are depolarized due to a continuous influx of sodium ions through cGMP-gated channels, maintaining a steady release of glutamate neurotransmitter. This constant release of glutamate signals the dark adaptation state of the photoreceptor.
Ionic compounds do not exhibit isomerism because the ions in an ionic compound are arranged in a specific ratio dictated by their charges to maintain overall electrical neutrality. The fixed arrangement of the ions in an ionic compound does not allow for the rearrangement of atoms or groups that is necessary for isomerism to occur.
An ionic bond is formed by the transfer of electrons from one atom to another, resulting in the attraction between oppositely charged ions. A covalent bond is formed by the sharing of electrons between atoms. Ionic bonds typically occur between metals and non-metals, while covalent bonds usually occur between non-metal atoms.
Ionic bonds occur between atoms of different electronegativities, typically between a metal and a nonmetal. In an ionic bond, one atom transfers electrons to another atom, resulting in the formation of ions with opposite charges that are attracted to each other.
Phosphorus trifluoride is a covalent compound. It is formed through the sharing of electrons between phosphorus and fluorine atoms, rather than the transfer of electrons that would occur in an ionic bond.
Ionic bonds generally occur between a metal and a nonmetal. Metals tend to lose electrons to form positively charged ions, while nonmetals tend to gain electrons to form negatively charged ions, creating an electrostatic attraction that holds the ions together in an ionic bond.

Photoreceptors allow light to be converted into signals that allow for biological processes. They are essential for the process known as photosynthesis. Photoreception occurs under light conditions when the photoreceptors absorb photons.
Ionic bonds are formed by electrostatic attraction.
Parallel events are similar events. Simultaneous events are events that occur at the same time. Both simultaneous and parallel events occur at different places.
in order in which events occur.
Glucose has covalent bonds.
No, it is not correct.
An ionic bond is formed by the transfer of electrons from one atom to another, resulting in the attraction between oppositely charged ions. A covalent bond is formed by the sharing of electrons between atoms. Ionic bonds typically occur between metals and non-metals, while covalent bonds usually occur between non-metal atoms.
They occurred then.
Transduction occurs in the retina of the eye. The retina contains specialized cells called photoreceptors (rods and cones) that convert light signals into electrical signals, which are then transmitted to the brain via the optic nerve for visual processing.
You call them 'sequence of events'.
