We have also learnt that photosynthesis is a vital process that occurs in order to create glucose and oxygen, by transforming carbon dioxide and water in the presence of light energy.
The result of two light reactions is a total of six oxygen molecules (6 O2) released into the air as byproducts and 12 NADPH2 (24 H) carried over to the dark reaction of photosynthesis....
Chemical changes occur almost all the time. The change that converts one substance into another is known as a chemical change. During a chemical change, the composition of the substance is changed. When a chemical change occurs new substances are formed through a reorganization of the atoms. A chemical change is irreversible. An example of chemical change is the fireworks explosion. Chemical Changes are also called Chemical Reactions. The chemical reaction produces one or more products, which usually have properties different from the reactants and have different physical and chemical properties. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, and might need some type of energy, viz. heat, or electricity to initiate the reaction.
Introduction: "Photosynthesis is the conversion of light energy to chemical energy that is stored in glucose or other organic compounds; it occurs in plants, algae, and certain prokaryotes" (Campbell, G-16).
This desire to discover new ways of producing clean energy has lead scientists at Stanford University and other universities to discover a way to harness the electricity produced during the process of photosynthesis.
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:
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.
Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight.
Fermentation does not require oxygen.
what is the chemical reaction for photosynthesis?
The green light we can see is not/cannot be absorbed by the plant, and thus cannot be used to do photosynthesis.
The overall chemical reaction involved in photosynthesis is: 6CO2 + 6H2O (+ light energy) → C6H12O6 + 6O2.
what are the differences between photosynthesis and cellular respiration?
photosynthesis needs energy to make glucose, while cellular respiration uses this glucose to actually create energy.
The chemical equation of photosynthesis is: [IMAGE]6CO2 + 6H20 C6 H12 O6 + 6O2 it has been proven many times that plants need light to be able to photosynthesize , so you can say that without light the plant would neither photosynthesize or survive....
This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...
Because this process is the result of the competition of molecular oxygen and carbon dioxide for Rubisco, photorespiration reduces the overall yield of photosynthesis (light plus dark reaction).
