The materials used to create an item are like the reactants, and the item itself is like the products.
The Process of Photosynthesis is like Manufacturing a Product
The Equation for Photosynthesis
The equation for photosynthesis is 6 carbon dioxide molecules added to 6 water molecules added to light energy, which produces 6 oxygen molecules and 1 glucose molecule.
This equation can be compared to equations that are inputted into machines to alter or add to a product.
The Energy Conversion in Photosynthesis
Photosynthesis is the only way on Earth to convert the Sun's energy into energy that our bodies can use.
The portion of photosynthesis takes place in the STROMA (clear areas of the chloroplast) and does not require light energy to proceed, but does require the products the (ATP and NADPH) of the light Rx. These are sometimes referred to as the "driving force" behind the Dark Rx. The Dark Rx is also referred to as the Calvin Cycle or the Carbon Fixation Cycle. This is where Carbon Dioxide is used in the photosynthesis process, and the CO2 provides the carbon atom which is the structural backbone of the glucose molecule.

Current understanding is that the earliest photosynthetic organisms were aquatic bacteria, some of which are still around today. One of these, halobacterium halobium, grows in extremely salty water. It makes use of the bacteriorhodopsin pigment. The chlorophyll system developed to use the available light, as if it developed in strata below the purple bacteria and had to use what it could get.
Pigments for Photosynthesis - HyperPhysics Concepts
The of a is the amount of biomass produced through photosynthesis per unit area and time by plants, the primary producers. Primary productivity is usually expressed in units of energy (e.g., joules m day ) or in units of dry organic matter (e.g., kg m year ). Globally, primary production amounts to 243 billion metric tons of dry plant biomass per year. The total energy by plants in a community through photosynthesis is referred to as (). Because all the energy fixed by the plant is converted into sugar, it is theoretically possible to determine a plant's energy uptake by measuring the amount of sugar produced. A proportion of the energy of gross primary productivity is used by plants in a process called . Respiration provides a plant with the energy needed for various plant physiological and morphological activities. The general equation for respiration is:
It has the composition C 55 H 72 O 5 N 4 Mg
The product of photosynthesis is a , such as the sugar , and oxygen which is released into the atmosphere (Figure 9l-1). All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight (Figure 9l-1). This chemical reaction is catalyzed by acting together with other , , , , and molecules. Sugars created in photosynthesis can be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates, such as . Sugars can also be combined with other such as nitrogen, phosphorus, and sulfur, to build complex molecules such as proteins and nucleic acids.

This portion of photosynthesis (LIGHT Rx) is sometimes referred to as the light dependent Rx, in that light energy is always required for it to proceed. It is also know as the Hill Rx. This part of photosynthesis is divided into two phases, or SYSTEMS, called PHOTOSYSTEM II and PHOTOSYSTEM I. Reference Fig. 7.6, pg. 113 in text, and read carefully the text material on pgs. 112-114.
