Is carbon removed during photosynthesis?
Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2. However, these processes are not in balance. Not all organic matter is oxidized.
What happens to carbon atoms when plants respire?
Some of the carbon atoms in the glucose exit the leaf as carbon dioxide during respiration while other carbon atoms are used to make important parts of the plant, such as additional leaves or wood. Carbon atoms that remain in leaves will either fall off (during plant senescence) or become a meal for an animal.
Why is carbon dioxide needed in photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
What is carbon fixation in photosynthesis?
Carbon fixation is a biosynthetic pathway by which atmospheric carbon is converted into metabolically active organic compounds. Carbon fixation in plants during photosynthesis utilises ATP and NADPH to assimilate carbon dioxide and form carbohydrates.
What happens to carbon atoms as a result of cellular respiration by plants animals and other organisms?
The carbon combines with oxygen to form carbon dioxide (CO2) and is released back into the atmosphere as a waste product when animals breathe and exhale.
How photosynthesis and cellular respiration are involved in the carbon cycle?
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
How is carbon used in photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Does photosynthesis produce carbon dioxide?
Carbon dioxide is not released during photosynthesis, but small amounts of that gas are emitted both day and night as a by-product of cellular respiration.
What happens during carbon fixation?
Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. In plant cells, the Calvin cycle is located in the chloroplasts.
Which of the following happens during the carbon fixation reactions of photosynthesis?
Which of the following occurs during the carbon-fixation reactions of photosynthesis? Water is converted into hydrogen and water.
How does carbon flow between photosynthesis and cellular respiration?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What happens to carbon dioxide during the carbon cycle?
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Why is carbon important for photosynthesis?
This energy makes carbon molecules an excellent source of fuel for all living things. During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel—glucose and other sugars—for building plant structures. This process forms the foundation of the fast (biological) carbon cycle.
What form does carbon take after photosynthesis?
carbon dioxide Photosynthesis by land plants, bacteria, and algae converts carbon dioxide or bicarbonate into organic molecules. Organic molecules made by photosynthesizers are passed through food chains, and cellular respiration converts the organic carbon back into carbon dioxide gas.
What are the end products of photosynthesis?
The products of photosynthesis are glucose and oxygen. Oxygen passes out of the leaves through the stomata.
How does carbon fixation occur in photosynthesis?
The light independent reactions, which include the Calvin cycle and, subsequently, carbon fixation, occur in the stroma. These reactions use ATP and NADPH to fix CO2 and produce glucose. The stroma is the cytoplasm of the chloroplast, or the open space between the thylakoids.
How carbon dioxide is fixed in photosynthesis?
The carbon-fixation pathway begins in the mesophyll cells, where carbon dioxide is converted into bicarbonate, which is then added to the three-carbon acid phosphoenolpyruvate (PEP) by an enzyme called phosphoenolpyruvate carboxylase.
How does carbon move in cellular respiration?
This carbon dioxide is generated through the process of cellular respiration, which has the reverse chemical reaction as photosynthesis. That means when our cell burn food (glucose) for energy, carbon dioxide is released. We, like all animals, exhale this carbon dioxide and return it back to the atmosphere.
How does carbon flow between photosynthesis and cellular respiration quizlet?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
What is carbon cycle process?
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
How does carbon dioxide affect photosynthesis?
Carbon dioxide and rate of photosynthesis An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor.
What is the end product of photosynthesis are carbon dioxide?
Photosynthesis involves the use of water and carbon dioxide to produce glucose and oxygen that are further assisted by Light and chlorophyll.
Is carbon dioxide a reactant or product of photosynthesis?
During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
How is carbon dioxide fixed as carbon in plants?
The carbon-fixation pathway begins in the mesophyll cells, where carbon dioxide is converted into bicarbonate, which is then added to the three-carbon acid phosphoenolpyruvate (PEP) by an enzyme called phosphoenolpyruvate carboxylase.
How does carbon flow between photosynthesis and respiration?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What are the 4 steps in the carbon cycle?
Photosynthesis, Decomposition, Respiration and Combustion. Carbon cycles from the atmosphere into plants and living things.
What are the 3 steps of the carbon cycle?
The carbon cycle is divided into the following steps:
- Entry of Carbon into the Atmosphere. …
- Carbon Dioxide Absorption By Producers. …
- Passing of the Carbon Compounds in the Food Chain. …
- Return of the Carbon To the Atmosphere.

Is carbon dioxide necessary for photosynthesis?
This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots.
What does photosynthesis end with?
The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of oxygen and water.
What is the final product of photosynthesis?
Answer: Photosynthesis is an activity performed by plants to produce glucose and oxygen as products. The main end product of photosynthesis is carbohydrates. It is a crucial process that succours in the preparation of food by plants in nature. The glucose produced by plants is reserved in the form of starch.
