1. what's a huge difference between the chemical equations for Respiration and Alcoholic fermentation &... What determines whether a facultative organism will go through respiration or fermentation
*For the first part of the Question, (I looked it up but I wasn't sure if it's talking about aerobic respiration or anaerobic resp or general)
* Is the second part of the question bc of the little erngy and the low Oxygen O2 levels?
3. What is the advantage of (Facultative organism) this method of energy production?

Choose from the general topics at the right and then find the specifics you need within each topic.
1. The chemical equations for respiration and alcoholic fermentation are different because they involve different metabolic pathways and different sets of reactions to produce energy.
- Respiration, specifically aerobic respiration, occurs in the presence of oxygen and is the process by which cells break down glucose to produce energy in the form of ATP. The balanced chemical equation for aerobic respiration is:
C6H12O6 + 6O2 -> 6CO2 + 6H2O + Energy (ATP)
- Alcoholic fermentation, on the other hand, occurs in the absence of oxygen and is a process used by some organisms, such as yeast, to convert sugars into alcohol and carbon dioxide. The balanced chemical equation for alcoholic fermentation is:
C6H12O6 -> 2C2H5OH + 2CO2 + Energy (ATP)
2. The determination of whether a facultative organism will go through respiration or fermentation depends on the availability of oxygen and the energy needs of the organism.
- In the presence of abundant oxygen, a facultative organism will typically choose respiration as it provides a more efficient way to generate energy. Respiration produces a larger amount of ATP per molecule of glucose compared to fermentation.
- In conditions of low oxygen levels or when oxygen is completely absent, the organism will switch to fermentation to produce energy. Fermentation is a less efficient process, but it allows the organism to continue producing ATP in the absence of oxygen.
So, the choice between respiration and fermentation by a facultative organism is primarily driven by the oxygen availability and the organism's need for energy.
3. The advantage of facultative organisms using fermentation as a method of energy production is their ability to survive in varying environmental conditions. By being adaptable, these organisms can switch between respiration and fermentation based on the oxygen availability.
- In aerobic conditions, respiration allows them to maximize ATP production and utilize oxygen efficiently.
- In anaerobic conditions or low oxygen levels, fermentation enables them to still produce ATP, albeit at a lower efficiency, ensuring their survival even when oxygen is limited or absent.
This ability to switch between energy production methods provides facultative organisms with greater flexibility, allowing them to cope with changes in their environment and continue to generate energy under a diverse range of conditions.
