What process turns carbon dioxide into organic molecules?

What process turns carbon dioxide into organic molecules?

Photosynthesis by land plants, bacteria, and algae converts carbon dioxide or bicarbonate into organic molecules.

What process produces organic molecules?

photosynthesis
Virtually all organic material on Earth has been produced by cells that convert energy from the Sun into energy-containing macromolecules. This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1).

Which process changes carbon dioxide into organic molecules burning fossil fuels cellular respiration evaporation photosynthesis?

Photosynthesis converts carbon dioxide gas to organic carbon, while respiration cycles the organic carbon back into carbon dioxide gas. Long-term storage of organic carbon occurs when matter from living organisms is buried deep underground and becomes fossilized.

What happens to carbon dioxide molecules in the Calvin cycle reactions?

The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.

In which cellular process is carbon dioxide released into the atmosphere?

cellular respiration
During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration. Respiration is also the process by which once-living (organic) organisms are decomposed.

What happens to the carbon dioxide molecules?

This indicates that all of the carbon dioxide molecules disintegrate into carbon and oxygen atoms at an extremely high temperature.

What happens to oxygen and carbon dioxide in a plant cell?

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. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

What happens to organic carbon when it decomposes?

In special cases, when dead plant matter builds up faster than it can decay, layers of organic carbon become oil, coal, or natural gas instead of sedimentary rock like shale. This coal seam in Scotland was originally a layer of sediment, rich in organic carbon.

What happens to carbon dioxide and water during photosynthesis?

This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

How does carbon flow from one reservoir to another?

Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components. Any change in the cycle that shifts carbon out of one reservoir puts more carbon in the other reservoirs.
