How does photosynthesis affect the carbon dioxide balance of the atmosphere?

One of the key elements in photosynthesis, is carbon dioxide. As we need food, so do plants. Plants do this by taking neutriance water, the suns energy and carbon dioxide to create a substance called glucose. This reduces the amount of carbon in the air, and in the process releases oxygen for us to breathe.


Is rubisco able to bind with carbon dioxide and oxygen?

Rubisco will only fix oxygen when carbon dioxide is in short supply or inaccessible (most commonly because of closed or partially closed stomata). When rubisco fixes oxygen instead of carbon, it is called photorespiration. This process probably evolved as an adaption to hot dry environments with limited amounts of carbon dioxide; however, photorespiration is a highly inefficient process.


Is cotton Gossypium hirsutum a C3 plant?

Yes, cotton (Gossypium hirsutum) is a C3 plant because it uses the C3 photosynthetic pathway. This means it initially fixes carbon dioxide into a three-carbon compound during photosynthesis.


By which enzyme is carbon first fixed in C4 photosynthesis?

With the help of the enzyme RuBisCo this reaction takes place. CO2 + ribulose biphosphate ( a 5 C sugar ) -> 2(3-phosphoglycerate)( 3 C sugar) This happens in the Calvin cycle. With CO2 and RuBP a reaction takes place with ATP and NADPH to do a complicated bit of arranging with the three CO2's coming into the cycle. Six of the 3-phosphogylcerates are made, but only one the product of one cycle and the rest go back into the cycle. The 3 carbon sugar then can be used to build glucose or used in the mitochondria for energy.


Why is photorespiration wastful process?

Photorespiration is considered wasteful because it consumes energy and resources without producing useful compounds for the plant. It occurs when rubisco enzyme fixes oxygen instead of carbon dioxide, leading to the release of CO2 and consumption of ATP and reducing power. This process reduces the efficiency of photosynthesis and can limit plant growth in certain conditions.


Role of carbonic acid in living organisms?

Carbonic acid plays a crucial role in maintaining the body's acid-base balance by acting as a buffer that helps regulate pH levels. It is formed in the blood when carbon dioxide combines with water, and is essential for proper respiratory and renal function. Carbonic acid also helps transport carbon dioxide in the blood to the lungs for exhalation.


What fixes carbon in photosynthesis?

The enzyme Rubisco, or Ribulose-1,5-bisphosphate carboxylase oxygenase in the C3 pathway. In the CAM and C4 pathways, PEP Carboxylase (Phosphoenolpyruvate carboxylase) fixes carbon instead.See related links below for more information on Rubisco and PEP Carboxylase.

What part does respiration plays in the carbon cycle?

Respiration is the process by which organisms release carbon dioxide into the atmosphere as a byproduct of breaking down organic compounds to produce energy. This carbon dioxide can then be taken up by plants during photosynthesis, completing the carbon cycle by forming carbohydrates that can be consumed by other organisms.
