What is a source of energy for chemosynthesis quizlet?

chemosynthesis is the biological conversion of one or more carbon molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic (e.g. hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis.

What is a source of energy for chemosynthesis?

Chemosynthesis is the conversion of carbon (usually carbon dioxide or methane) into organic matter using inorganic molecules (hydrogen or hydrogen sulfide) or methane as an energy source. Most energy is initially derived from sunlight via plant photosynthesis.

What is a source of energy for chemosynthesis group of answer choices?

Chemosynthesis is a process by which energy is derived via the microbial mediation of certain chemical reactions. The source of energy for chemosynthesis is energy liberated from a chemical reaction (the oxidation of an inorganic substance) rather than energy harvested from sunlight or other light.

What is needed for chemosynthesis to occur quizlet?

A process in which glucose is produced from carbon dioxide and water using chemical nutrients rather than the sunlight used in photosynthesis.

Where do chemosynthetic organisms get their energy?

Chemosynthetic bacteria, unlike plants, obtain their energy from the oxidation of inorganic molecules, rather than photosynthesis.

What happens in chemosynthesis quizlet?

chemosynthesis is the biological conversion of one or more carbon molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic (e.g. hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis.

What are the reactants in chemosynthesis?

Reactants: A carbon-containing inorganic compound, such as carbon dioxide or methane. This will be the source of the carbon in the organic molecule at the end of the process. A chemical source of energy such as hydrogen gas, hydrogen sulfide, or ferrous iron.

What is the chemosynthesis equation?

hydrogen sulfide chemosynthesis: 18H2S + 6CO2 + 3O2 → C6H12O6 (carbohydrate) + 12H2O + 18S. Instead of releasing oxygen gas while fixing carbon dioxide as in photosynthesis, hydrogen sulfide chemosynthesis produces solid globules of sulfur in the process.

Is chemosynthesis aerobic or anaerobic?

Chemosynthesis may be coupled to both aerobic and anaerobic respiration. Aerobic chemosynthesis depends on oxygen, which ultimately originates from photosynthetic processes occurring in the photic zone.

How does chemosynthesis cycle matter and energy?

Chemosynthesis exploits chemical energy to convert inorganic carbon compounds into organic matter, in contrast with photosynthesis, which exploits the energy of light to produce organic matter. … Energy is produced in chemosynthetic reactions from oxidizing reduced compounds.

What is the main purpose of chemosynthesis quizlet?

Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways.

What do chemosynthesis and photosynthesis have in common quizlet?

What are the similarities between chemosynthesis and photosynthesis? Both processes need carbon dioxide to produce the carbohydrates. Both processes also need an energy source to fuel the reactions. … In photosynthesis, water is needed to fuel the process; in chemosynthesis, water is an end result of the process.

Where does chemosynthesis occur?

Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent.

What is the process of chemosynthesis Brainly?

Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent.

What organisms use chemosynthesis?

Chemoautotrophs, for instance, are organisms that perform chemosynthesis. They include certain groups of bacteria such as sulfur-oxidizing gamma proteobacteria, epsilon proteobacteria, and neutrophilic iron-oxidizing bacteria, and certain archaea such as methanogenic archaea.

How do chemosynthetic Autotrophs get their energy?

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. … Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis.
