Glucose and water
glucose (C6H12O6)
Oxygen.
Oxygen is the reactant needed for cellular respiration that is absent from the fermentation reaction. In the absence of oxygen, some organisms, like yeast, undergo fermentation to produce energy in the form of ATP.
Glucose; lactate
Sugar can be both a reactant and a product, depending on the chemical reaction. For example, in the process of photosynthesis, sugar (glucose) is produced as a product. However, in the process of fermentation, sugar is a reactant that is broken down to produce other products like ethanol and carbon dioxide.
Yes, oxygen is a common reactant in cellular respiration, specifically in aerobic respiration where it serves as the final electron acceptor in the electron transport chain. In contrast, fermentation does not require oxygen and occurs in the absence of it, utilizing alternative pathways to generate energy.
The reactants in fermentation are typically sugar molecules, such as glucose or sucrose, along with yeast or certain bacteria that act as catalysts to break down the sugars into alcohol or acids. These microorganisms convert the sugars into energy in the absence of oxygen through a process known as anaerobic respiration.
The Limiting Reactant is the reactant that runs out first in a reaction.
