The process of fixing carbon dioxide into carbohydrates occurs during what process of photosynthesis?
light independent
What incorporation of carbon dioxide into organic compounds?
Carbon fixation is the process by which carbon from carbon dioxide is incorporated into organic compounds.Specifically, fixation describes a conversion from inorganic to organic. The process is carried out by living organisms. Organisms known as autotrophs - e.g., plants - will grow by conducting carbon-fixing photosynthesis. Others known as heterotrophs - e.g., animals - will grow by using an autotroph's fixed carbon.
Which situation best accounts for photorespiratin in plants?
Photorespiration is more likely to occur in plants when the ratio of oxygen to carbon dioxide is high, such as in hot and dry environments. This leads to Rubisco, the enzyme involved in photosynthesis, fixing oxygen instead of carbon dioxide, resulting in the wasteful process of photorespiration.
What are the carbon fixing reactions that occur in photosynthesis called?
The carbon fixing reactions in photosynthesis are called the Calvin cycle or the light-independent reactions. In this process, carbon dioxide is converted into organic molecules with the help of ATP and NADPH produced during the light-dependent reactions.
Which is the most abundant carbon-fixing enzyme on earth?

What is the loss of carbon-fixing activity of the enzyme RuBP carboxylase directly proportional to?
The loss of carbon-fixing activity of the enzyme RuBP carboxylase is directly proportional to the rate of photorespiration in the plant. As photorespiration increases, the enzyme's efficiency in fixing carbon dioxide decreases, leading to reduced photosynthetic productivity.
Is nitrogen used in the air?
Yes nitrogen is used in the air by certain plants. The process is called fixing. There is 78% in the air and the rest is carbon dioxide (0.03%), oxygen (21%) and argon (1%).
The carbon cycle works in conjunction with what?
The carbon cycle is closely related to photosynthesis. Photosynthesis is the process by which carbon is exchanged from the atmosphere (in the form of CO2) into the biosphere (in the form of glucose).
What does rubisco do?
Rubisco is an enzyme involved in carbon fixation during photosynthesis. It catalyzes the first step of the Calvin cycle, where it combines carbon dioxide and ribulose-1,5-bisphosphate (RuBP) to form two 3-phosphoglycerate molecules. This process is essential for plants to convert atmospheric carbon dioxide into organic molecules that can be used for growth and energy production.
What is the role of microorganisms in returning nitrogen or carbon dioxide to the atmosphere?
this microorganisms is called denitrifying bacteria, it helps to decompose the nutrients (nitrogen) back to the atmosphere. and the process of returning nitrogen or carbon dioxide to the atmosphere is called denitrification.
What does RuBP mean?
RuBP stands for ribulose-1,5-bisphosphate. It is a five-carbon molecule involved in the Calvin cycle, a series of reactions in photosynthesis where carbon dioxide is converted into glucose. RuBP is regenerated during the cycle to ensure its continuous availability for fixing carbon dioxide.

How is carbon added to the atmosphere?
Carbon is most commonly added to the atmosphere via the burning of fossil fuels and other carbonaceous compounds. The process of burning or combustion releases water vapor and carbon dioxide into the atmosphere. Common sources of carbon: -Coal burning power plants -Gasoline powered cars -Forest fires and deforestation via burning -Methane release from swamps Also, the oceans actually act as a large carbon sink or reservoir and because of the nature of carbon dioxide, the warmer that water gets, the less carbon dioxide it can dissolve. As a result, as ocean temperatures increase, they actually lose the ability to store carbon dioxide and more is released into the atmosphere. Photosynthesis actually acts to remove carbon from the atmosphere by fixing it into chemical energy in the form of sugars and releasing pure oxygen in the process.
