Chemosynthesis does not require light to make glucose in this unit you should learn the following 1 explain the process of photosynthesis 2 explain the process. When discussing chemosynthesis vs photosynthesis, one important factor that distinguishes these two processes is the use of sunlight chemosynthesis occurs in darkness, on the seafloor, whereas, photosynthesis requires light energy from the sun to make food. But photosynthesis is not the only method that living organisms use to create energy some microorganisms derive energy from chemical reactions that don't require light and use this energy to assemble organic molecules through a process called chemosynthesis. Chemosynthesis occurs in environments where sunlight is not able to penetrate, such as in hydrothermal vents at the bottom of the ocean, coastal sediments, volcanoes, water in caves, cold seeps in the ocean floor, terrestrial hot springs, sunken ships, and within the decayed bodies of whales, among many others.

Some organisms make food through the process of chemosynthesis this action does not require sunlight for food production instead, plants make food using several chemical reactions, such as the combination of oxygen and methane or hydrogen sulfide. Chemolithotrophy or chemosynthesis is the basis of the primary productivity at deep-sea hydrothermal vents, and its discovery challenged our traditional view that all ecosystems were driven by light energy and photosynthesis the chemolithotrophic microbes are found free-living as well as associated as symbionts with the invertebrates.
Unlike photosynthesis, chemosynthesis does not involve the use of light energy but energy derived from oxidation-reductions that must be adequate for the synthesis of adenosine triphosphate (atp) and that must exceed 10 kcal/mole.

Unlike photosynthesis, chemosynthesis requires no light and can occur at the extreme temperatures and high pressures characteristic of the deep ocean environment the.
The foods consist of carbohydrates, such as glucose, but these require energy to manufacture where sunlight is available, autotrophs will generally use it to perform photosynthesis, but in places where no light reaches, different types have evolved that use chemical energy instead. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation.
Even though it forms about 04% of the air, it is a needed factor in light-independent photosynthesis in higher concentrations, more carbon is incorporated into carbohydrate, therefore increasing the rate of photosynthesis in light-independent reactions. Autotrophs that perform chemosynthesis do not use energy from the sun to produce food instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (eg, hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis.
The first process is the light dependent process (light reactions), requires the direct energy of light to make energy carrier molecules that are used in the second process the light independent process (or dark reactions ) occurs when the products of the light reaction are used to form c-c covalent bonds of carbohydrates. Does chemosynthetic bacteria need sunlight photosynthesis and chemosynthesis are processes by which organismsproduce food photosynthesis is powered by sunlight, whilechemosynthesis runs on. Chemosynthesis is the use of energy released by inorganic chemical reactions to produce food chemosynthesis is at the heart of deep-sea communities, sustaining life in absolute darkness, where sunlight does not penetrate. The energy releasing reactions which converts them back to energy-depleted adp and nadp is known as dark phase reactions (calvin cycle) (does not require light) in which the synthesis of glucose and other carbohydrates occurs.
As the alvin reaches the bottom of the ocean, there is no natural light the pilots plot the position of the sub with both standard navigation equipment and with special topographical (or 3-d) maps that are made by side scan sonar. Chemosynthesis organisms tube worms the tube worm is a worm that lives on the bottom of the ocean it can reach the length of 7 feet, 10 inches, and the diameter of the body can get up to 16 inches. Electron transport chain, photosystem ii and i, b6-f complex, and nadp reductase require light the calvin cycle does not require light the atp synthase complex itself does not require light. Photosynthesis - part i: the sun and light not all of the light from the sun makes it to the surface of the earth even the light that does make it here is reflected and spread out.
