Photosynthesis vs. the Food Chain
Photosynthesis powers almost all trophic chains and food webs on the Earth.
That's whywe call it PHOTOsynthesis.
Please make sure that you have memorized the word equation for photosynthesis, and the balanced chemical equation if you are doing the higher papers. You can find these equations and an explanation of how to balance chemical equations here.
Photosynthesis is a process used by plants in which energy from sunlight is used to convert carbon dioxide and water into molecules needed for growth. These molecules include sugars, enzymes and chlorophyll.
What Are Photosynthesis and Respiration?
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.
According to NASA, of all the sunlight that reaches earth, only about 48 percent of it hits the surface and only a portion of that is captured through photosynthesis. The rest is reflected back by earth’s atmosphere or absorbed by the atmosphere.
we need water for photosynthesis).
Respiration, at the cellular level, is a set of connected metabolic processes that are directed towards converting stored biochemical energy in food, into ATP (Adenosine Triphosphate) molecules, which are the body's energy currency.
Following photosynthesis, the glucose constructed within plant cells can then be used as a source of energy and materials for cellular activities such as growth, reproduction and the synthesis of more complex materials such as starch, proteins, and fats. The existence of all naturally-occurring molecules (any molecule containing carbon, , and oxygen), and therefore, all sources of energy, can be traced back to the process of photosynthesis. This concept will become very important as we study the flow of energy through ecosystems and the use of energy by humans later in the course.

our topic right now, namely photosynthesis,is arguably one of the most important chemical reactions occurring on theplanet. Let's see why.
Standard III- Photosynthesis and Cellular Respiration
This phenomenon is called photosynthesis, and is the process of converting light energy (harvested from sunlight) into chemical energy (sugars) by the green plants.
The following equation sums up the photosynthesis reaction:
Energy is defined as the ability to do work. The cells of all organisms, and therefore, all organisms, require a continuous supply of energy for the performance of their daily, vital activities. Carbohydrates, especially glucose, generally provide this energy through the process of respiration. Simply stated, respiration is the release of energy from energy-storing compounds. It is represented by the chemical equation:
Energy in Cells Photosynthesis Vs Cellular Respiration.
The chemical equation for respiration is:C6H12O6 + 6O2 6CO2 + 6H2OGlucose + Oxygen Carbon Dioxide + WaterThe key points: Glucose stores the sun's energy in chemical form.
The raw materials neededfor photosynthesis include ...
To be more precise, photosynthesis is carried out in the chloroplasts with the help of chlorophyll pigments.
This equation basically is a chemical representation of photosynthesis in a reaction form, which takes place in the chloroplasts.
Which word equation summarizesphotosynthesis?
You should be careful to notice that the process of cellular respiration is essentially the reverse of photosynthesis. The catabolic breakdown (burning) of glucose requires the presence of oxygen and yields energy and . This process is generally the same when any organic molecule is respired (or burned) whether it is glucose in a living animal or plant cell, wood in a fire, or gasoline in a car. The breakdown of any energy storing chemical releases carbon dioxide as a byproduct, which may then be used by plants in the photosynthetic process.
Photosynthesis and Cellular Respiration
If you have a brief idea about the required raw materials and the products of this process, you will easily understand the chemical reactions.
In photosynthesis, carbon dioxide is used as a substrate base for producing glucose and oxygen with the help of light energy and water.
