Aerobic VS Anaerobic Respiration Flashcards
In anaerobic respiration, what process follows glycolysis?
After glycolysis in anaerobic respiration, fermentation (either lactic acid fermentation or alcoholic fermentation) occurs
How many ATP molecules are produced during anaerobic respiration, and from which process do they come?
2 ATP molecules are produced, and they come from glycolysis (since fermentation doesn’t produce additional ATP).
TF
Fermentation produces ATP
False - it doesn’t produce ATP
What are the two types of fermentation that occur in anaerobic respiration?
The two types of fermentation are lactic acid fermentation and alcoholic fermentation
What are alcoholic and lactic acid fermentation?
Lactic acid fermentation is a biological process in which glucose (or other sugars) is converted into energy in the form of ATP (adenosine triphosphate), with lactic acid as a byproduct. This type of fermentation occurs in the absence of oxygen (anaerobic conditions).
Alcoholic fermentation is another anaerobic process in which sugars (typically glucose) are converted into ethanol (alcohol) and carbon dioxide, also producing ATP. This process is used by many yeasts and some bacteria.
Comparison:
End products: lactic acid (lactate)/ ethanol (alcohol) and CO2
Organisms: muscle cells, certain bacteria/ yeasts, some bacteria
Byproducts: lactic acid/ ethanol and CO2
ATP yield: 2 molecules per 1 glucose for both
Oxygen requirement: both anaerobic.
Both types of fermentation serve to regenerate NAD+ (from NADH), which is crucial for continuing glycolysis when oxygen is not available, allowing cells to keep producing ATP under anaerobic conditions.
List the stages involved in aerobic respiration.
The stages are glycolysis, Krebs Cycle, and Electron Transport Chain (ETC).
What is the purpose of the Electron Transport Chain (ETC) in aerobic respiration?
The ETC is used to produce ATP by transferring electrons through a series of proteins, ultimately converting ADP to ATP
