Graded Discussion Board (GDB) GSC101

Dear Students!

It is informed that the GDB of this course will be opened on  June 24, 2024 at 12:00 am. This discussion board will be closed on June 25, 2024 at 11:59pm. 

“GDB will remain open for 48 hours”

It is important for every student to take part in this discussion board. Your comments will be graded, which is worth 5% of your total marks.


The Topic is:

“ A very small amount of matter is converted into energy during a combustion reaction. Is this true, and if so, is it also true for cellular respiration? ''''Give scientific principle/ reasoning in support of your comments''''

 GDB’s Instructions

  • Provide precise and to the point answer, not more than 3 to 4 lines, avoid irrelevant details.
  • Post your answer on the Graded Discussion Board (GDB), not on the Moderated Discussion Board (MDB).
  • No more time or grace day will be provided.

Note: Anyone who copy and paste the comments of others will be graded ZERO marks.

 


Answer:

Yes, a very small amount of matter is converted into energy during a combustion reaction, and this is also true for cellular respiration. Both processes adhere to Einstein's mass-energy equivalence principle, E=mc^2, which states that energy (E) is equal to mass (m) multiplied by the speed of light (c) squared.

Combustion Reaction

In combustion, a fuel reacts with oxygen to produce carbon dioxide, water, and energy. For example, in the combustion of methane:


The energy released as heat and light comes from the breaking and forming of chemical bonds. The mass of the reactants is slightly greater than the mass of the products, with the difference converted to energy.



Cellular Respiration

Similarly, cellular respiration converts glucose and oxygen into carbon dioxide, water, and energy:



Here, the energy produced is stored in ATP molecules, which cells use for biological functions. The process involves a small mass loss as energy is released during the metabolic breakdown of glucose.

 

In both processes, the conversion of a tiny amount of mass into energy illustrates the practical application of mass-energy equivalence, demonstrating how chemical reactions in both inorganic and biological systems can release significant amounts of energy.
