Why do most plants appear green?
Liono4ka [1.6K]

Answer:

Most plants appear green because they absorb all other colors of light and reflect back green into our eyes. Since chlorophyll molecules use the red (opposite of green) end of the visible light spectrum to complete photosynthesis, then red is most heavily absorbed.

Structure is the result of two or more protein subunits assembling to form a larger, biologically active protein complex.
cluponka [151]

A larger, biologically active protein complex is created when two or more protein subunits come together to form a quaternary structure.

A protein's quaternary structure is formed when several protein chains or subunits come together in a compact configuration. There are separate primary, secondary, and tertiary structures for each of the subunits. Hydrogen bonds and van der Waals forces between nonpolar side chains hold the subunits together.

For a quaternary structure to function as a whole, the subunits must be arranged in a particular way. Any change to the subunits' structure or how they are linked results in noticeable adjustments in biological activity.
