Photosynthesis Flowchart - Explore the Secret of Nature

On Friday, Google paid tribute to Jan Ingenhousz, a Dutch scientist born in 1730 who discovered the photosynthetic process, used by plants use to convert sun light into food.

Chemically speaking, respiration is photosynthesis in reverse, as you can see in this equation:

Photosynthesis Process that plants use to convert light energy (energy from the sun) into sugar that the plant can use as fuel
Uses up water and carbon dioxide and produces sugar and oxygen Chloroplasts are small sections of a plant cell that contain chlorophyll
Chlorophyll is where photosynthesis occurs, and is what makes plants green Produces the oxygen we breathe
Produces the sugars plants need for energy, which in turn provides animals with energy when they eat those plants
Removes the greenhouse gas carbon dioxide from the atmosphere Overview of the Electromagnetic (Light) Spectrum An "electron shell" is like a bubble around the nucleus of the atom that can contain only a certain number of electrons.
Electrons are "happiest" (at their lowest energy) when they are paired
You can tell how reactive an atom is depending on how many unpaired electron it has in its electron shell
(see electron shell powerpoint_ The number of protons in the nucleus determines which element an atom is.
Example: an atom with 8 protons will always be an oxygen atom
A hydrogen ion (H+, or a hydrogen without its electron) is also referred to as a proton note: nm = nanometer = 1 billionth of a meter this is how much of the spectrum the human eye can see!

Fun foldable that introduces students to the process of photosynthesis.

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.

The following steps walk you through the photosynthesis process that occurs each time the sun’s light reaches the leaves of a plant:

You have already studied the "dark reaction" and I will refer you to Dr. Diwan's notes on the subject. As the overall process of photosynthesis involves a series of electron transfer reactions, we are in the realm of oxidation-reduction chemistry, and it would help to review the basics of these processes because we will be going into this topic in greater depth. There is a direct analogy to electron transfer in the mitochondrion, in which clumps of energy are transferred from one electron carrier to another along a "chain" and H+ ions are translocated out, across the mitochondrial membrane, thus generating an electrochemical gradient. The energy inherent in this gradient is used to synthesize ATP in the process of "oxidative phosphorylation." The same processes occur in photosynthesis and the chloroplast, the site of photosynthesis in plants and blue-green algae (but not in photosynthetic bacteria), is the analog of the mitochondrion in eukaryotes.

Schematic Vector Illustration Of The Photosynthetic Process

During photosynthesis, a process that occurs in plants and in cyanobacteria and also in purple photosynthetic bacteria, light energy is converted into chemical energy. The overall process is described by the chemical equation:

We'll look at a simpler example of photosynthesis first, and use it as an introduction to photosynthesis in plants and cyanobacteria (blue-green algae). Although the primary reactions of photosynthesis take place at "photosynthetic reaction centers," the first level of interaction of light with an organism that carries out photosynthesis is at an assembly of chlorophyll molecules that "harvest" light (the "light-harvesting complex"). Such an assembly results in a greater chance that photons will be captured and, because of the strategic arrangement of the individual chlorophyll and other accessory light-absorbing molecules, the transfer of energy to the photosynthetic reaction center is very fast (-10 s) and very efficient (>90%).

Both the LHC and the reaction centers are membrane bound structures but there are no chloroplasts in the purple photosynthetic bacteria. The electron transfer processes occur within the cell membrane and the overall process is a cyclic one (i.e., there is no net oxidation-reduction). Protons are transferred across the membrane, from the cytoplasmic side to the outside, establishing a proton gradient whose dissipation drives ATP synthesis. A similar situation holds for the cyanobacteria and plants, but in these organisms, the process occurs in chloroplasts and the overall reaction is not a cyclic one.
