What would happen to the fermentation process? NAD+ would not be regenerated so glycolysis would not be able to run, so no pyruvate would be produced so there are no reactants for fermentation to proceed. While you rest, the demand for ATP decreases and oxygen debt is "paid off." Lactic acid is converted back to pyruvate and aerobic respiration can resume
In this case, carbon dioxide gets used to produce sugars in a series of reactions called the Calvin Cycle, C4 photosynthesis, and crassulacean acid metabolism. There are a couple of ways this works in cells: -glycolysis, in which glucose is broken up into two subunits, called pyruvate, which creates two units of ATP per molecule of glucose
Cellular Respiration
Remember that for each molecule of glucose, two Acetyl Co-A molecules are produced; therefore the KCAC occurs twice for each glucose, so all products here are X 2.
Cellular Respiration
Because there are a number of enzymes and steps involved in forming porphyrin rings, there are a number of possible points in the process where genetic defects could occur. Out of many possible types of fermentation processes, two of the most common types are lactic acid fermentation and alcohol fermentation (other types of fermentation such as methanol fermentation and acetone fermentation also exist)
Cellular Respiration
What is the chemical formula for glucose? The chemical equation for respiration is: C6H12O6 + 6O2 6CO2 + 6H2O Glucose + Oxygen Carbon Dioxide + Water The key points: Glucose stores the sun's energy in chemical form. Electron transport produces an uneven charge on the mitochondria membrane.This allows protons to move through the membrane by electrical charge attraction
Cellular Respiration
This has strengthened the theory that mitochondria are the evolutionary descendants of a bacterium that established an endosymbiotic relationship with the ancestors of eukaryotic cells early in the history of life on earth. (Defects in either process can produce serious, even fatal, illness.) The Outer Membrane The outer membrane contains many complexes of integral membrane proteins that form channels through which a variety of molecules and ions move in and out of the mitochondrion

How many ATP molecules are produced by one molecule of glucose
The formation of ATP from ADP requires energy, thus ATP can be synthesized through the energy released by the splitting of a higher-energy phosphate molecule. Some high-energy phosphate molecules have a lower free energy of hydrolysis than ATP, meaning more energy is released by the removal of a phosphate group
