A scientist is studying the catabolism of glucose in a particular strain of bacteria. Normally, that species of bacteria produces 10 NADH, 2 FADH2, and 4 ATP from the theoretical net yield of a single glucose molecule. They calculates that the theoretical net yield is only 2 ATP and 4 NADH in this strain. Provide an explanation for what is happening and why. Use the different parts of cellular respiration in all parts of your explanation.
Electron Transport Chain
The electron transport chain, also known as the electron transport system, is a group of proteins that transfer electrons through a membrane within mitochondria to create a gradient of protons that drives adenosine triphosphate (ATP)synthesis. The cell uses ATP as an energy source for metabolic processes and cellular functions. ETC involves series of reactions that convert redox energy from NADH (nicotinamide adenine dinucleotide (NAD) + hydrogen (H)) and FADH2(flavin adenine dinucleotide (FAD)) oxidation into proton-motive force(PMF), which is then used to synthesize ATP through conformational changes in the ATP synthase complex, a process known as oxidative phosphorylation.
Metabolism
Picture a campfire. It keeps the body warm on a cold night and provides light. To ensure that the fire keeps burning, fuel needs to be added(pieces of wood in this case). When a small piece is added, the fire burns bright for a bit and then dies down unless more wood is added. But, if too many pieces are placed at a time, the fire escalates and burns for a longer time, without actually burning away all the pieces that have been added. Many of them, especially the larger chunks or damp pieces, remain unburnt.
Cellular Respiration
Cellular respiration is the cellular process involved in the generation of adenosine triphosphate (ATP) molecules from the organic nutritional source obtained from the diet. It is a universal process observed in all types of life forms. The glucose (chemical formula C6H12O6) molecules are the preferred raw material for cell respiration as it possesses a simple structure and is highly efficient in nature.

Cellular respiration involved in catabolic reactions where larger molecules break down into smaller ones. Cellular respiration is defined as series of metabolic reactions and processes that are taking place in the cells of organisms that convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP) and then release waste products. It is an aerobic process by which living cells break down glucose molecules, releases energy, and form ATP molecules. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the stages of cellular respiration.
