Respiration in Plants Test - 1

Glycolysis is the metabolic process by which glucose is converted to pyruvate (also known as pyruvic acid). The process of glycolysis is important in producing energy for the cell, particularly in anaerobic conditions. It occurs in the cytosol of the cell.

The word glycolysis is of Greek origin, where 'glycos' means sweet, and 'lysis' means splitting.

In anaerobic respiration, glucose breaks down without oxygen. 
The chemical reaction transfers energy from glucose to the cell.
Anaerobic respiration produces lactic acid(C₃H₆O₃), rather than carbon dioxide and water. 

Hence, option D is correct.

Glycolysis is common to both aerobic respiration and anaerobic respiration.

In the first step, each glucose molecule (6 carbon molecules) is broken down into two molecules of pyruvate (3 carbon molecules) by the process of glycolysis. 
The process occurs in the cytoplasm of the cell and does not require the presence of oxygen. 

Glycolysis is the first stage of the breakdown of glucose in the cell. 

During glycolysis, 2 ATP molecules are used up and 4 ATP molecules are generated.
In the entire process of glycolysis, two NADH₂ molecules are also generated. When these molecules undergo ETS they will form 3 ATP per NADH₂  which means 6 ATP.

Therefore,
total ATP that is forming is 10 and as 2 ATP is used up.

Glycolysis takes place in the cytoplasm of a cell as the first step in cellular respiration of the Kreb’s cycle. When glycolysis occurs, it breaks down glucose into pyruvic acids in the cytoplasm.
