The global carbon cycle is largely biological, and over past millennia has been close to a steady state. That is, the uptake to the biosphere via photosynthesis has been balanced by the losses in respiration. The amount of carbon held in the vegetation and soils pools together is more than three times the total carbon in the atmosphere.
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.
Photosynthesis & Respiration can be summarized into equations.
Photosynthesis is the process whereby plants use sunlight to convert atmospheric carbon dioxide into organic compounds, such as sugars and starches. All the food we eat is produced by or dependent on photosynthesis, and photosynthesis also provides us with wood, fibres and other plant products.
Carbon is cycled through photosynthesis and cellular respiration
Chemically respiration is the opposite of photosynthesis. During respiration cells release energy by converting glucose and oxygen into water an carbon dioxide.
Difference between Respiration and Photosynthesis | …
Photosynthesis is the biochemical process in which energy from sunlight is converted by plants, algae, and some bacteria into sugars, which are used by the organism as food. That is, these organisms convert the energy of the sun into a different form of energy.
Photosynthesis & Respiration can be summarized into equations
Students conduct a hands-on experiment that illustrates how different levels of light affect photosynthesis and respiration in seagrass. Note: instructor may need to be creative with timing of the experiment to allow for an adequate incubation period.
respiration if photosynthesis and ..
In respiration energy is released fromsugars when electrons associated with hydrogen are transported to oxygen (theelectron acceptor), and water is formed as a byproduct. The mitochondriause the energy released in this oxidation in order to synthesize ATP. Inphotosynthesis, the electron flow is reversed, the water is split (not formed),and the electrons are transferred from the water to CO2 and in theprocess the energy is used to reduce the CO2 into sugar. Inrespiration the energy yield is 686 kcal per mole of glucose oxidized to CO2,while photosynthesis requires 686 kcal of energy to boost the electrons from thewater to their high-energy perches in the reduced sugar -- light provides thisenergy.
through the processes of photosynthesis and respiration.
Algae are a very diverse group of predominantly aquatic photosynthetic organisms that account for almost 50% of the photosynthesis that takes place on Earth. Algae have a wide range of antenna pigments to harvest light energy for photosynthesis giving different types of algae their characteristic colour. Early work done with algae contributed much to what is presently known about the carbon dioxide fixation pathway and the light harvesting reactions. The processes of photosynthesis in algae and higher plants are very similar. From among the three types of carbon dioxide‐concentrating mechanisms known in photosynthetic organisms, two types are found in different types of algae. Algae are proposed to play a role in the global carbon cycle by helping remove excess carbon dioxide from the environment. Recently, algae are recognized as a promising biodiesel source due to its efficient absorption and conversion of solar energy into chemical energy.
