Which of the following is common to both Aerobic and Anaerobic respiration?

Which of the following is common to both Aerobic and Anaerobic respiration? Correct Answer Glycolysis

The correct answer is Glycolysis.

Key Points

• Glycolysis
  • It is a common phase between aerobic and anaerobic respiration.
  • Glycolysis is also called the EMP pathway.
  • It is the metabolic pathway that converts glucose into pyruvic acid.
  • This pathway does not require oxygen.
  • The energy released in the process forms the high-energy ATP (adenosine triphosphate) molecules.
  • It also reduces NADH (nicotinamide adenine dinucleotide).
  • It is a sequence of ten reactions that are catalyzed by enzymes.
  • The final product of glycolysis is lactate in anaerobic respiration and pyruvate in Aerobic respiration.

Important Points

• Respiration
  • It is a chemical reaction taking place in all livings cells along with the release of energy from glucose.
  • There are two types of respiration.
• Anaerobic respiration
  • It occurs in the absence of oxygen and releases less energy.
  • It is faster than aerobic respiration.
  • It is common in plants.
  • In microorganisms, this type of respiration is called fermentation.
• Aerobic respiration
  • It occurs in the presence of oxygen.
  • Glycolysis is the primary step of aerobic respiration.
  • It occurs in the mitochondria of the cell.
  • It is common in animals and humans.

Additional Information

• Kreb's cycle
  • It is also known as the citric acid cycle or tricarboxylic acid cycle (TCA).
  • It is a series of chemical reactions to release stored energy through oxidation.
  • Organisms use this cycle in the respiration process to generate energy.
  • The cycle is a precursor of certain amino acids.
  • It is also used as the reducing agent NADH.
• Alcoholic fermentation
  • It is also known as ethanol fermentation.
  • It is a biological process that converts sugars such as glucose, fructose or sucrose into cellular energy.
  • It produces ethanol and carbon dioxide as by-products.
  • It is considered as an anaerobic process since it occurs in the absence of oxygen.
  • It is used in the fermentation of alcoholic beverages and bread dough.
• Lactic acid fermentation
  • It is a metabolic process by which glucose is converted into cellular energy.
  • It is an anaerobic fermentation reaction.
  • It occurs in bacteria and animal cells.
