Does chemosynthesis need oxygen?
Aerobic chemosynthesis depends on oxygen
, which ultimately originates from photosynthetic processes occurring in the photic zone. Anaerobic chemosynthesis depends on terminal electron acceptors other than oxygen (e.g., S
0
, SO
4
2 –
, CO
2
, Fe
3 +
, NO
3 –
, etc.), and therefore it is independent from photosynthetic processes.
What chemosynthesis needs?
During chemosynthesis, bacteria living on the sea floor or within animals use
energy stored in the chemical bonds of hydrogen sulfide and methane
to make glucose from water and carbon dioxide (dissolved in sea water).
Is oxygen produced in chemosynthesis?
Chemosynthesis (at hydrothermal vents)
hydrogen sulfide (H2S), add carbon dioxide (CO2) and
oxygen (O2)
and produce sugar (CH2O), sulfur (S), and water (H2O): This is one example of a chemosynthetic pathway.
What does chemosynthesis not require?
How does chemosynthesis get energy?
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
.
Does chemosynthesis require light?
Chemosynthesis is the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals,
typically in the absence of sunlight
.
How are photosynthesis and chemosynthesis different?
Photosynthesis and chemosynthesis are both processes by which organisms produce food;
photosynthesis is powered by sunlight while chemosynthesis runs on chemical energy
.
What do chemosynthesis and photosynthesis have in common?
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.
What is chemosynthesis short answer?
Definition of chemosynthesis
:
synthesis of organic compounds (as in living cells) by energy derived from inorganic chemical reactions
.
Does photosynthesis produce oxygen?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen
and energy in the form of sugar.
How does the process chemosynthesis work?
Chemosynthesis is the process by which
certain microbes create energy by mediating chemical reactions
. So the animals that live around hydrothermal vents make their living from the chemicals coming out of the seafloor in the vent fluids!
What is chemosynthesis BBC Bitesize?
The producers are bacteria which feed directly on the chemicals released from the vents and use a variety of chemical reactions to make glucose
. This process is called chemosynthesis.
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.
How much ATP does chemosynthesis produce?
Since 2 ATP molecules are used in glycolysis, the net amount of ATP created is
36
.
Is oxygen required for photosynthesis?
Yes, it is
. Plants need oxygen to survive, and plant cells are constantly using oxygen. Under certain circumstances, plant cells need to take in more oxygen from the air than they generate themselves. So, if plants generate oxygen through photosynthesis, why do plants need oxygen?
Does chemosynthesis use ATP?
Like photosynthesis and cellular respiration,
chemosynthesis uses an electron transport chain to synthesize ATP
. After having its electrons passed through the electron transport chain, the chemical fuel source emerges in a different form.
What is another word for chemosynthesis?
•Other relevant words: (noun)

, synthesis.
Which photosynthesis process produces oxygen?
Do plants need oxygen or carbon dioxide?
What phase of photosynthesis produces oxygen?
The Light Reactions
The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains. During the
light reactions
, water is used and oxygen is produced.
Does chemosynthetic bacteria need sunlight?
chemosynthetic bacteria prepare their own food without the help of sunlight
. Additional Information: -Chemosynthetic bacteria, because of their important feature of producing their own food without sunlight, they are able to survive in any type of environment.
What is the waste product of chemosynthesis?
In chemosynthesis, the hydrogen from H2S combines with carbon dioxide to form sugar, the bacteria’s food; and
sulfates
, the bacteria’s waste product.
Why do leaves take in oxygen in the dark?
What are the four things needed for the process of photosynthesis?
There are four factors which are necessary for the process of photosynthesis,
water, carbon dioxide, sunlight, and chlorophyll
.
What is the name of respiration that occurs in the absence of oxygen?
Anaerobic respiration
does not need oxygen (unlike aerobic respiration). It is the release of a relatively small amount of energy in cells by the breakdown of food substances in the absence of oxygen.
Which compound can provide the energy for chemosynthesis quizlet?
Chemosynthesis uses chemical energy to drive is chemical processes (usually from extreme environments). It uses
carbon dioxide, hydrogen sulfides and oxygen
to produce carbohydrates and sulfur compounds.
Which group of organisms can make food by a process called chemosynthesis?
How does energy pass from one organism to another?
A food chain
is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
Does chemosynthetic bacteria need sunlight?
Where does chemosynthesis take place?
Is chemosynthesis used by decomposers?
Decomposers are defined by their ability to eat the leftovers of other living organisms, which classifies them as heterotrophs. Most chemosynthetic bacteria do not eat other organisms or their decaying bodies, so
they are not decomposers or consumers but rater producers
.
