A
Lactic acid and ATP
B
Oxygen and glucose
C
Carbon dioxide and water
D
Pyruvate and NADH
Verified step by step guidance1
Understand that fermentation is an anaerobic process, meaning it occurs without oxygen. This is crucial for identifying the correct products.
Recall that there are two main types of fermentation: lactic acid fermentation and alcoholic fermentation. Each type produces different products.
In lactic acid fermentation, which occurs in muscle cells and some bacteria, the main products are lactic acid and ATP. This process regenerates NAD+ from NADH, allowing glycolysis to continue.
In alcoholic fermentation, which occurs in yeast and some types of bacteria, the products are ethanol, carbon dioxide, and ATP. This process also regenerates NAD+ from NADH.
Review the options given: Lactic acid and ATP are the products of lactic acid fermentation, while oxygen and glucose, carbon dioxide and water, and pyruvate and NADH are not products of fermentation processes.
