The residence time of carbon in the reservoir that leads to the respiration process, primarily in living organisms, typically ranges from days to years. This is due to the continuous cycling of carbon through processes like photosynthesis, respiration, and decomposition. In ecosystems, carbon is quickly exchanged among the atmosphere, biosphere, and soils, resulting in relatively short residence times compared to geological carbon reservoirs, which can range from thousands to millions of years.
Water is the compound that is split during photosynthesis, producing oxygen and hydrogen ions in the process. This splitting of water is a crucial step in the light-dependent reactions of photosynthesis that ultimately leads to the production of ATP and NADPH for use in the Calvin cycle.
Photosynthesis is alkaline because it involves the uptake of carbon dioxide from the atmosphere, which leads to the release of oxygen as a byproduct. The conversion of carbon dioxide into carbohydrates results in a decrease in hydrogen ions in the chloroplasts, making the solution more alkaline. This alkalinity helps drive the reactions of the Calvin cycle, which leads to the synthesis of sugars and other organic compounds.
The acceptor of carbon dioxide in photosynthesis is ribulose-1,5-bisphosphate (RuBP) in the Calvin cycle. RuBP combines with carbon dioxide in the presence of the enzyme RuBisCO to form an unstable 6-carbon compound, which eventually leads to the production of sugars.
Ribulose bisphosphate captures carbon dioxide molecules in the process of carbon fixation during photosynthesis. It is a key molecule in the Calvin cycle, where it combines with carbon dioxide to form an unstable six-carbon compound that eventually leads to the production of sugars.
Factors that affect the rate of photosynthesis include light intensity, carbon dioxide levels, and temperature. Higher light intensity usually leads to faster photosynthesis, as does higher carbon dioxide levels. However, extremely high temperatures can inhibit the process as they can damage the enzymes involved.
Photosynthesis helps reduce Global Warming by taking in carbon dioxide. If there is too much of it, then carbon dioxide keeps the sunlight inside earth's atmosphere making the earth warmer. This leads on to global warming, but photosynthesis helps reduce parts of the effect. A recent Scientific Article stated that CO2 reclamation could be Adequately Accomplished by the Revisioning of all of Our land use and Agricultural practices.
When oxygen is produced more than carbon dioxide, it leads to an increase in oxygen levels in the atmosphere. This can occur during processes like photosynthesis in plants, which convert carbon dioxide into oxygen. The excess oxygen can benefit organisms that rely on it for respiration.
It is because plants breathe and live on a little bit of carbon dioxide, which humans and animals breathe out, and cannot survive on. So when the plants take in carbon dioxide they then let go of oxygen which is what we breathe. So that leads us on to the fact that during photosynthesis plants need a lot of carbon dioxide which then is changed into oxygen. We then take in oxygen and give them carbon dioxide, and it repeats over and over again.
Deforestation contributes to the rise in carbon dioxide levels in the atmosphere because trees absorb carbon dioxide during photosynthesis. When trees are cut down or burned, the stored carbon is released back into the atmosphere, increasing the overall amount of carbon dioxide present. This leads to higher levels of carbon dioxide in the atmosphere, which contributes to global warming and climate change.
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.
Because photosynthesis requires carbon dioxide which we should all know is a very dangerous greenhouse gas (contributes to global warming) and therefore photosynthesis removes carbon dioxide from the atmosphere and it also produces oxygen which animals need to breathe. By the way, just so you know, global warming is basically caused by greenhouse gases building up around the earth and keeping heat in causing the earth to warm up. This leads to melted ice caps/flooding and dramatic climate changes.
