Reduce or stop the production of energy molecule i.e ATP
Explanation:
Proton is an essential ingredient to carry out light reactions successfully and the proton requirement is fulfilled through the proton gradient formed along the membrane. A chemical that blocks the flow of electrons thereby hindering the flow of proton will adversely affect the electron transport chain reactions thereby causing reduced/no conversion of ADP to ATP.
The opponent process theroy of color vision recommends that our capacity to perceive color is constrained by three receptor complexes with contradicting or opposing activities.
These three receptor complexes are as follows:
Dark white complex.
Blue-yellow complex.
Red-green complex.
You don't see greenish-red because according to the opponent process theory, the opponent cells can just identify each of these colors at a time.
