What happens to the 6 carbon atoms of glucose when it is completely degraded?

Degradation means that a large molecule is broken down into simpler ones. In this case, glucose which has a chemical formula of C6H12O6 is broken down into simple parts.

Assuming that the reaction takes the form below, glucose is usually converted into 6 units of carbon dioxide CO2.

C6H12O6  + reactant  -->  6CO2  + product

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
