What two major biological processes drive the carbon and oxygen cycles?
Photosynthesis drives the carbon cycle, combining carbon dioxide and water to produce glucose and oxygen. Respiration drives the oxygen cycle, breaking down glucose to release energy and produce carbon dioxide and water.
How does the process of converting carbon dioxide to oxygen occur in plants?
During photosynthesis, plants use sunlight to convert carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2). This process takes place in the chloroplasts of plant cells, where the pigment chlorophyll absorbs sunlight and drives the chemical reactions that produce oxygen as a byproduct.
Is opening a soda can a chemical change?
Nope. The pressure keeps the Carbon Dioxide dissolved in the liquid, and when that pressure is relieved, the CO2 rapidly returns to its gaseous state. None of the molecules are reacting or changing, although the CO2 switches from aqueous to gaseous phase.
What is light reaction and dark reaction?
Photosynthesis can be divided into two part: light reaction is the first stage of photosynthesis, occurring only in the presence of light, during which energy captured from light drives the production of ATP. dark reaction is the second stage of photosynthesis, not requiring light to occur, and during which energy released from ATP drives the production of organic molecules from carbon dioxide.
What trap the energy from the sun and change it into chemical energy in a cell?
Chloroplasts trap energy from the sun and convert it into chemical energy through the process of photosynthesis in plant cells. The chlorophyll pigment within chloroplasts absorbs sunlight, which drives the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

How does carbon dioxide get out of your bloodstream?
It is gas exchange in the alveoli that gets the carbon dioxide (CO2) out of the blood and the oxygen (O2) in. What is actually going on is that the partial pressure of CO2 in the blood is greater than that of the CO2 in the air. The CO2 will diffuse out of the blood into the air, driven by that difference in partial pressure. And diffusion, driven by the higher partial pressure of O2 in the air drives that oxygen in the air into the blood. A link can be found below to an animated short that explains the process. Check it out.
Which process drives the gas exchange from the alveoli to the capillaries?
Diffusion is the process that allows the exchange of oxygen and carbon dioxide in the alveoli. This process is one of passive transport.

Do most scientists agree that there is conclusive evidence that carbon dioxide drives climate?
Yes, the vast majority of climate scientists agree that there is conclusive evidence showing that carbon dioxide and other greenhouse gases are driving climate change. This consensus is supported by multiple lines of evidence, including historical data, climate models, and physical principles.

What toxic gases are released during coke production?
carbon dioxide Answer: Coke is produced in an oxygen deprived atmosphere so the combustion gases include both carbon dioxide and carbon monoxide. The coking process drives out various aromatics from the coal which may escape (although most are retained as they are valuable) these include benzene and toluene. Cracked and reformed hydrocarbons may also be emitted such as PAHs
Why does burning fossil fuels create energy?
Burning fossil fuels releases stored chemical energy in the form of heat. This heat is used to generate steam, which then drives turbines to produce electricity. The carbon and hydrogen in fossil fuels combine with oxygen to form carbon dioxide and water, releasing energy in the process.
IS hydrogen necessary in the electron transport chain comes from the splitting of carbon dioxide molecules?
Hydrogen is essential in the electron transport chain, but it does not come from the splitting of carbon dioxide molecules. Instead, hydrogen is derived from the splitting of water molecules during the light reactions of photosynthesis. This hydrogen is then used to generate a proton gradient that drives ATP synthesis in the electron transport chain.
Why might it be helpful for people to know how much carbon dioxide their daily travels released?
If people had an easy way of knowing exactly how much their daily travels contributed to carbon dioxide emissions they might take some steps to reduce it. Someone who drives their car to the corner shop might reflect that walking that short distance would mean fewer emissions. It could also lead to a healthier lifestyle for themselves.
What is the source of energy that drives the movement of the lithospheric platesWhat is the source of energy that drives the movement of the lithospheric plates?
The source of energy that drives the movement of the lithospheric plates is believed to be the heat generated by radioactive decay in the Earth's interior, primarily in the mantle. This heat creates convection currents that cause the plates to move over the semi-fluid asthenosphere beneath them.
