the transport of products of photosynthesis carried out …
Both chlorophyll and other pigments within the chloroplast are able to absorb solar energy.
Plants convert solar energy to chemical energy.
Throughout the cell, chemical energy can be transported to other parts of the plant and kept in store.
Photosynthesis converts these energy- depleted compounds (ADPand NADP+) back to the high energy forms (ATP and NADPH) and theenergy thus produced in this chemical form is utilized to drivethe chemical reactions necessary for synthesis of sugars andother carbon containing compounds (e.g., proteins, fats). Theproduction of high energy ATP and NADPH in plants occurs in whatis known as Light Phase Reactions (Z Scheme) (requiressunlight). The energy releasing reactions which converts themback to energy-depleted ADP and NADP is known as Dark PhaseReactions (Calvin Cycle) (does not require light) in whichthe synthesis of glucose and other carbohydrates occurs.

Plant photosynthesis, both the Light Phase and Dark phasereactions, takes place in chloroplasts, which may be regarded asthe "power plants" of the green leaf cells. At night,when there is no sunlight energy, ATP continues to be generatedfor the plant's needs by respiration, i.e., oxidation of(photosynthetically produced) carbohydrate in mitochondria(similar to animals).
Photophosphorylation is the production of ATP using the energy of sunlight. Photophosphorylation is made possible as a result of chemiosmosis. Chemiosmosis is the movement of ions across a selectively permeable membrane, down their concentration gradient. During photosynthesis, light is absorbed by chlorophyll molecules. Electrons within these molecules are then raised to a higher energy state. These electrons then travel through Photosystem II, a chain of electron carriers and Photosystem I. As the electrons travel through the chain of electron carriers, they release energy. This energy is used to pump hydrogen ions across the thylakoid membrane and into the space within the thylakoid. A concentration gradient of hydrogen ions forms within this space. These then move back across the thylakoid membrane, down their concentration gradient through ATP synthase. ATP synthase uses the energy released from the movement of hydrogen ions down their concentration gradient to synthesise ATP from ADP and inorganic phosphate.

Photosynthesis Similarities Differences The Relationship Between the Processes Works Cited There are a number of similarities between these two series of reactions such as their equations, transformation of energy, exchange of gases, the Eletron Transport Chain and Chemiosmosis, and the theory of endosymbiosis.

The electrons go through a transport chain which amounts to a kind of respiration in the middle of photosynthesis, in other words the energetically favorable transfer from -0.8 V to +0.4 V drives the synthesis of some ATP.
Photosynthesis: Crash Course Biology #8 - YouTube
So we can summarize by saying that the photosynthetic plantstrap solar energy to form ATP and NADPH (Light Phase) and thenuse these as the energy source to make carbohydrates and otherbiomolecules from carbon dioxide and water (Dark Phase),simultaneously releasing oxygen in to the atmosphere. Thechemoheterotrophic animals reverse this process by using theoxygen to degrade the energy-rich organic products ofphotosynthesis to CO2 and water in order to generate ATP fortheir own synthesis of biomolecules.
photosynthesis notes - Biology Junction
In a broad chemical sense, the opposite of photosynthesis isrespiration. Most of life on this planet (all except in the deepsea vents) depends on the reciprocal photosynthesis-drivenproduction of carbon containing compounds by a series of reducing(adding electrons) chemical reactions carried out by plants andthen the opposite process of oxidative (removing electrons)chemical reactions by animals (and plants, which are capable ofboth photosynthesis and respiration) in which these carboncompounds are broken down to carbon dioxide and water.
IB Biology Notes - 8.2 Photosynthesis
Photosynthetic organisms can be divided into two classes:those which produce oxygen and those which do not. Photosyntheticbacteria do not produce oxygen (in fact some of them calledanaerobes cannot tolerate oxygen) and this is considered a moreprimitive type of photosynthesis (in which the hydrogen donor ishydrogen sulfide, lactate or other compounds, but not water).Plants and one type of bacteria (cyanobacteria) do produceoxygen, an evolutionarily more advanced type of photosynthesis(in which the hydrogen donor is water).
Energy - Royal Society of Chemistry
For each electron flowing from water to NADP+ (a net change in1.14 volts), two quanta of light are absorbed, one by eachPhotosystem. Each molecule of oxygen released involves the flowof four electrons from two water molecules to two NADP+s andrequires four quanta of sunlight absorbed by each Photosystem toprovide the energy to do this. These are the "Light PhaseReactions" of photosynthesis, which produce two high energychemical products, namely NADPH and ATP.
