Movement of carbon and related molecules through the spheres of the earth transfers carbon from the atmosphere to the biosphere
which is Krebs cycle and which is carbon cycle
The movement of carbon and related molecules from the atmosphere to the biosphere is part of the carbon cycle. Specifically, this transfer occurs during the process of photosynthesis. During photosynthesis, carbon dioxide (from the atmosphere) is converted into organic molecules, such as glucose, by plants and some other organisms. This process occurs in the biosphere.
On the other hand, the Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid cycle (TCA cycle), is a series of chemical reactions that occur in the mitochondria of cells. It is an integral part of cellular respiration, which is the process by which cells convert glucose and other organic molecules into energy (ATP). The Krebs cycle involves the breakdown of glucose and the release of carbon dioxide as a byproduct.
In summary, the movement of carbon and related molecules from the atmosphere to the biosphere is part of the carbon cycle, while the Krebs cycle is a part of cellular respiration involved in the breakdown of glucose and the release of carbon dioxide.
