Chemiosmosis in chloroplasts that results in the donation of a proton for the production of adenosine triphosphate (ATP) in plants.

Chloroplasts and Photosynthesis

All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes. It is believed that the first organisms on the primitive Earth had access to an abundance of the organic

The Light-Dependent Reactions of Photosynthesis

Figure 1. Light energy is absorbed by a chlorophyll molecule and the photon is passed along a pathway to other chlorophyll molecules. The energy culminates in a molecule of chlorophyll found in the reaction center. The energy "excites" one of its electrons enough to leave the molecule and be transferred to a nearby primary electron acceptor.

Light-Dependent and Light-Independent Reactions

Energy from the sun excites the electron again, giving it enough energy to pass across the membrane and into the stroma, where it joins with a hydrogen ion and an NADP + to create the energy-carrying molecule NADPH. ATP and NADPH move from the thylakoid into the stroma, where the energy they store is used to power the light-independent
