Solution:

Glycolysis is the process of breaking down glucose (a 6C chemical) into two pyruvic acid molecules (a 3C compound). It takes place in the cell’s cytoplasm. Two pyruvates (pyruvic acid) molecules, four ATP molecules, and two NADH molecules are the end products of glycolysis. Glycolysis is a process that takes place in both aerobic and anaerobic organisms. If the cells have oxygen, glycolysis is followed by a process known as the citric acid cycle or tricarboxylic cycle. If there isn’t any oxygen, the fermentation process begins.


Plants obtain energy by respiration, which is the most common technique. In the presence of oxygen, glucose is one of the principal dietary molecules that breaks down to generate carbon dioxide and water. Respiration happens predominantly through the leaves and roots of the plant and is necessary for its survival. Stomata are the microscopic holes that allow gas exchange to take place on the surface of the plant’s leaves.
