The main result of aerobic respiration is the
1 conversion of radiant energy into chemical energy
2 production of lactic acid as an end product
3 storage of energy in a polysaccharide
4 production of ATP from the breakdown of glucose
The correct answer is option 4: production of ATP from the breakdown of glucose.
To arrive at this answer, let's break down the process of aerobic respiration. Aerobic respiration is a series of biochemical reactions that occur in the presence of oxygen. It is the main process by which cells convert glucose (a sugar molecule) into energy in the form of ATP (adenosine triphosphate).
During aerobic respiration, glucose undergoes a series of chemical reactions in a cell's mitochondria. These reactions involve the breakdown of glucose into smaller molecules, releasing energy in the process. This energy is then used to produce ATP molecules.
The overall chemical equation for aerobic respiration is:
C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + ATP (energy)
As you can see, glucose is broken down into carbon dioxide and water, while ATP is produced. ATP is a high-energy molecule that provides the fuel for cellular processes. It powers various activities within the cell, such as muscle contraction and active transport.
Therefore, the main result of aerobic respiration is the production of ATP from the breakdown of glucose.
