Answer:
Glycolysis produces a net ATP of 2 in comparison to the 28-30 produced during ETC
Explanation:
The process of cellular respiration in eukaryotic cells consists of three steps namely: glycolysis, kreb cycle, and oxidative phosphorylation (electron transport chain).
- Glycolysis, which represents the first step can occur with or without oxygen in the cell, hence, glycolysis occurs in every cell. However, the process of glycolysis, which involves the breakdown of glucose into pyruvate in a series of biochemical steps makes use of 2ATP molecules at the beginning and later produces 4 ATP molecules. Therefore, a net ATP molecule of 2 is produced.
- However, as stated in this question, the aerobic phase of cellular respiration in the mitochondrion called Electron transport chain (ETC) produces about 28 to 30 ATP molecules.
Aerobic respiration involves the breakdown of glucose to yield energy in the presence of oxygen. In eukaryotic cell, the mitochondrion yield 28 to 30 ATP molecules, whereas during glycolysis 2 ATP molecules are produced.
Glycolysis is the process of breakdown of glucose molecule, which yields two molecules of pyruvate. The glycolysis generates 4 molecules of ATP, out of which 2 ATP molecules are utilised in the glycolysis. The net production of glycolysis is 2 ATP molecules.
The electron transport chain yields net 28 to 30 ATP molecules. The ETC takes place in the mitochondria, in which NADH is converted into ATP through a series of biochemical reactions.
The ATP net productions from different reactions are as follows:
- Kreb's cycle yields 2 ATP molecules
- Glycolysis yields 2 ATP molecules
- ETC yields approximate 30 ATP molecules.
Therefore, the glycolysis generates two molecules of ATP, whereas the ETC generates 28 to 30 ATP molecules.
