Living cells obtain the products of photosynthesis ..
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.

The regeneration of RuBP is essential for carbon fixation to continue. Five triose phosphate molecules will undergo a series of reactions requiring energy from ATP, to form three molecules of RuBP. RuBP is therefore consumed and produced during the light-independent reactions and therefore these reactions form a cycle which is named the Calvin cycle.
To determinewhich of these original compounds contributed to the O2 endproduct, an isotopic tracer experiment was performed using 18O:

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.

The site of photosynthesis is the thylakoid membrane, which contains integral and peripheral membrane protein complexes, including the pigments that absorb light energy, which form the photosystems. WHAT PIGMENTS ARE RESPONSIBLE FOR PHOTOSYNTHESIS?
Photosynthesis is the production of organic ..
Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.

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).
This tutorial introduces photosynthesis
The plants and cyanobacteria (which use water as a hydrogendonor and produce oxygen) have Photosystems I and II, whereas theless highly evolved other photosynthetic bacteria(which do notuse water as their hydgrogen donor and do not produce oxygen)have only Photosystem I.
