Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following are the primary products lactic acid fermentation? (Choose all that apply)
A
CO2
B
Ethanol
C
ATP
D
Lactate
E
FADH2
Explanation: 

Detailed explanation-1: -Lactic acid fermentation produces lactic acid (lactate) and NAD+. The NAD+ cycles back to allow glycolysis to continue so more ATP is made.

Detailed explanation-2: -Therefore, the products of lactic acid fermentation from one molecule of glucose include 2 ATP, 2 pyruvate, 2 molecules of lactic acid, and 2 NAD+.

Detailed explanation-3: -Products of Fermentation While there are a number of products from fermentation, the most common are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H2). These products are used commercially in foods, vitamins, pharmaceuticals, or as industrial chemicals.

Detailed explanation-4: -Lactic acid fermentation is a type of anaerobic respiration (or fermentation) that breaks down sugars to produce energy in the form of ATP. It is called anaerobic because it occurs in the absence of oxygen. Lactic acid is generated as a byproduct of this reaction, which is what gives this type of fermentation its name.

Detailed explanation-5: -Lactic acid bacteria (LAB) are heterogenous group of bacteria which plays a significant role in a variety of fermentation processes. They ferment food carbohydrates and produce lactic acid as the main product of fermentation.
