What statement is true about ATP production in fermentation and cellular?
In fermentation, ATP is produced through substrate-level phosphorylation, resulting in a low yield of ATP (typically 2 ATP molecules per glucose molecule). In contrast, cellular respiration, particularly aerobic respiration, generates a significantly higher yield of ATP (up to approximately 36-38 ATP molecules per glucose) through oxidative phosphorylation and the electron transport chain. While fermentation occurs in the absence of oxygen, cellular respiration requires oxygen for efficient ATP production. Thus, cellular respiration is a more efficient process for ATP generation compared to fermentation.
How are lactic acid fermentation and alchoholic fermentation similar?
Alcohol fermentation and lactic acid fermentation are similar because glucose is oxidized to two molecules of pyruvic acid. The difference between them is that alcohol fermentation yield two molecules of ATP also.
What is the net ATP yield?
The net ATP yield refers to the total number of ATP molecules produced during cellular respiration after accounting for the ATP consumed in the process. In aerobic respiration, the net yield is typically around 30 to 32 ATP molecules per glucose molecule, depending on the efficiency of the electron transport chain and the type of cell. In anaerobic conditions, such as fermentation, the yield is much lower, typically around 2 ATP per glucose molecule. This difference highlights the efficiency of aerobic metabolism compared to anaerobic pathways.
When oxygen is absent most of the ATP made in cellular respiration is produced by?
When oxygen is absent, most of the ATP produced in cellular respiration comes from anaerobic processes, primarily fermentation. In humans, this results in lactic acid fermentation, while in yeast, alcoholic fermentation occurs. Both processes regenerate NAD+ to allow glycolysis to continue, which produces a small amount of ATP. Overall, the yield of ATP in anaerobic conditions is significantly lower than in aerobic respiration.
Compare aerobic respiration and fermentation in terms of efficiency of obtaining energy from glucose?
Aerobic respiration is more efficient than fermentation in terms of obtaining energy from glucose because it produces a much higher yield of ATP molecules per glucose molecule. Aerobic respiration produces up to 38 ATP molecules per glucose molecule, while fermentation produces only 2 ATP molecules per glucose molecule.
How many molecules of ATP dose fermentation yield?
Two net molecules of ATP per fermentation cycle.

What is the biggest disadvantage of making ATP by means of fermentation?
The biggest disadvantage of making ATP by fermentation is that it produces a lower yield of ATP compared to aerobic respiration. This is because fermentation is an anaerobic process and does not fully oxidize glucose, resulting in less energy being produced per molecule of glucose.
How many molecules of ATP does fermentation yield?
During glycolysis it makes a net amount of 2 molecules of ATP. Fermentation happens anaerobically (without oxygen) and the reduction of pyruvate into lactate itself does not yield any ATP. But I think the answer you are looking for is 2 ATP.

Which gives the greater yield of ATP alcoholic fermintation or cellular respiration?
In aerobic respiration which incorporates oxygen, 36 molecules are produced per 1 molecule of glucose and in anaerobic respiration (fermentation) where no oxygen is incorporated, only 2 molecules are produced per 1 molecule of glucose
Compare aerobic respiration and fermentation in terms of efficiency of obtaining energy from glucose?
Aerobic respiration is more efficient than fermentation in terms of obtaining energy from glucose because it produces a much higher yield of ATP molecules per glucose molecule. Aerobic respiration produces up to 38 ATP molecules per glucose molecule, while fermentation produces only 2 ATP molecules per glucose molecule.
In what way are cellular respiration and fermentation alike in what ways are they different?
Both cellular respiration and fermentation are processes that break down glucose to produce energy in the form of ATP. However, cellular respiration occurs in the presence of oxygen and results in a much higher yield of ATP, while fermentation occurs in the absence of oxygen and produces lactic acid or ethanol as byproducts.
Is it false that the energy yield in aerobic respiration is far less than that which results from fermentation?
No, it is false. Aerobic respiration produces much more energy (in the form of ATP) compared to fermentation. This is because aerobic respiration involves the complete breakdown of glucose, while fermentation only partially breaks down glucose.
How can a skeletal muscle produce additional ATP when there is not enough oxygen?
Anaerobic fermentation enables a cell to produce ATP in the absence of oxygen but the ATP yield is very limited and the process produces a toxic end product, lactic acid, which is a major factor in muscle fatigue.
