Rhodopsin Activation and Structural Change Upon Photon Absorption.

Diagram illustrating the formation of rhodopsin from cis-retinal and opsin, and the molecular change in rhodopsin before and after photon absorption. The cis-retinal is shown in red inside the protein structure, which turns to trans-retinal in yellow after photon exposure, indicating a structural change in the protein.

This scientific illustration, ideal for biology or biochemistry textbooks, depicts the process of rhodopsin activation, a key event in the visual phototransduction pathway. The diagram illustrates the molecular changes from cis-retinal to trans-retinal and the structural transformation of rhodopsin, providing an essential visual for understanding the biochemistry of vision.

We can provide sample images or create custom illustrations tailored to your projects. If you are looking for an illustration of this type, or from another subject area, you can contact us to discuss your needs.
