of a plant using photosynthesis for energy
The figure illustrates how closely photosynthesis and respiration are linked. As you can see, thanks to these two life-sustaining processes, plants and animals depend on each other to survive.
Direct Harvesting of Electricity from Plant Photosynthesis
Water (H2O) is split in this process, releasing oxygen (O2) and hydrogen ions (H+). The electrons from the electron transport chain combine with these H+ ions and nicotinamide adenine dinucleotide phosphate ions (NADP+) to form adenosine triphosphate (ATP) and a reduced unit of NADP+, called NADPH (NADP plus an electron, or H). These energy storage forms, ATP and NADPH, are used to convert carbon dioxide (CO2) to build carbohydrates during the second phase of photosynthesis. Plants can then break down these carbohydrates to fuel their existence.
Respiration consists of a complicated series of chemical reactions. In the first stage, glucose is oxidized, and the chemical potential energy of its bonds is transferred to the chemical potential bonds of an ATP molecule. The ATP molecule can then be transported throughout the cell where its stored energy is used to complete various tasks within the cell. This process releases carbon dioxide gas and water.

The plant uses the stored chemical energy of ATP to make glucose from carbon dioxide. The plant then uses the glucose to make even larger compounds of cellulose and starch, which store energy.
Cellular Respiration and Photosynthesis
Environmental scientists recognize that the fundamental source of energy for most life on earth is the sun. Through photosynthesis, plants capture the light and convert it into chemical potential energy. Plants then store the potential energy in the form of (biological matter that fuels nearly every animal on earth).

While Flexer's method was originally optimized for observing and understanding photosynthesis kinetics rather than extracting electricity, Ryu et al. attempted to probe photosynthesis with their main focus on energy extraction.  In this work, the authors separated a single cell of algae called chlamydomonas reinhardtii, trapped the cell in a microchannel and inserted a nanoscale probe into the cell using an atomic force microscopy apparatus. This is a more controlled way of experiment in a sense that they are only looking at a single cell, and that a single cell of chlamydomonas only contains one chloroplast (it is still questionable, however, how effective this step is. After all there are more than one thylakoid stacks in a chloroplast, and it was unclear if the probe tip was located inside or outside the thylakoid membrane).
Cell Processes: Photosynthesis & Cellular Respiration
And, once you master your knowledge of photosynthesis, you can relax in the sun with a greater appreciation for the O2 you breathe, knowing that it is produced from the photosynthetic process. Don’t forget the sunscreen—at least SPF 30—you aren’t a plant, after all. Finally, you will realize that the beachside smoothie you are sipping, along with everything else that you have ever eaten, or will ever eat, relies on photosynthesis either directly or indirectly as its source of energy. Unless, of course, you have gotten into the habit of snacking on chemoautotrophs that live in rocks or deep-sea hydrothermal vents. They don't use photosynthesis.
Photosynthesis and cellular respiration are opposite ..
Respiration occurs in your cells and is fueled by the oxygen you inhale. The carbon dioxide gas you exhale is the result of a completed cycle of cellular respiration.
