Advantages and Disadvantages of
Aerobic and Anaerobic Respiration
LEARNING OBJECTIVES
describe the role of oxygen in
respiration and describe
pathways of electron flow in the
absence of oxygen
explain the fermentation
advantages and disadvantages
of Anaerobic and aerobic
respiration.
CELLULAR RESPIRATION
Is the process by which the biological fuels are oxidised and in the presence of inorganic acceptors such as Oxygen to produce a vast amount of energy, to drive the massive production of ATP (Adenosine Triphosphate).
Cellular Respiration can also occur both aerobically and anaerobically.
CELLULAR RESPIRATION
This may be described as a set of metabolic reactions and processes that takes place in the cells of an organism to convert chemical energy from nutrients into ATP.
The reactions who are involved in Respiration are the catabolic reaction, which break the energy down into small, similar molecules.
CELLULAR RESPIRATION
The overall equation for aerobic cellular respiration is
Three stages of Aerobic Respiration: Glycolysis (Anaerobic) KREBS Cycle (Aerobic) Oxidated Phosphorylation (Aerobic)
HANS ADOLF KREBS
He was a German-British Biologist, Physician and Biochemist. He was one of the pioneer scientist in the study of the Cellular Respiration, a biochemical process in living things that extracts energy from food and oxygen.
He received the 1953 Nobel Prize for Physiology or medicine for the living organisms of the series of chemical reactions known as Tricarboxylic acid cycle (also known as The Citric Acid Cycle or KREBS cycle).

COMMON MISTAKES AND MISCONCEPTIONS
COMMON MISTAKES AND MISCONCEPTIONS
Anaerobic Respiration is a normal part of Cellular Respiration.
Plants Undergoes Cellular Respiration.
COMMON MISTAKES AND MISCONCEPTIONS
Cellular Respiration is the same thing as breathing.
The relation of the processes to one another.
FERMENTATION
It is a metabolic process that produces chemical changes in organic substrates through the action of enzymes.
It is also the means of producing ATPs by the degradation of organic nutrients anaerobically.
FERMENTATION
Fermentation is a method to extract energies from molecules. This method is the only one common to all bacteria (prokaryotes) and Eukaryotes.
Humans also use fermentation to produce foodstuffs and beverages ever since the Neolithic ages. Notable examples are the Black Bean, Kombucha, Kimchi , Yogurt and Pickled Cucumber, and foods that produce Lactic acids which are found in sour foods.

ADVANTAGES AND DISADVANTAGES OF ANAEROBIC RESPIRATION
ADVANTAGES AND DISADVANTAGES OF ANAEROBIC RESPIRATION
ADVANTAGES
DISADVANTAGES
•All available energy extracted from Glucose is 40 ATPs. Prokaryotes have no Mitochondria or even Nucleus, so they can extract energy from Glucose, by approximately 40% of it. •43% of energies are transferred from Glucose to ATP.
•The 53% of Glucose metabolism becomes heat and enters the environment.

ADVANTAGES AND DISADVANTAGES OF ANAEROBIC RESPIRATION
ADVANTAGES
DISADVANTAGES
•The complete breakdown of Glucose into smaller molecules. •Anaerobic Respiration produces ATP much faster than Aerobic.
•Anaerobic Respiration only generates two ATPs and produces Lactic Acid.

ADVANTAGES AND DISADVANTAGES OF AEROBIC RESPIRATION
ADVANTAGES AND DISADVANTAGES OF AEROBIC RESPIRATION
ADVANTAGES
DISADVANTAGES
•61% of Glucose metabolism becomes heat and enters the environment. When the Glucose became heat, it can't be used by cells for energy reproduction.
•All available energy extracted from Glucose is ranging from 36 to 38 ATP.

ADVANTAGES AND DISADVANTAGES OF AEROBIC RESPIRATION
ADVANTAGES
DISADVANTAGES
•39% of energy are transferred from Glucose to ATP. •Lactate is returned to the liver to become pyruvate or be Glucose again.
•Human body cannot perform Lactic Acid Fermentation. •Human muscle cells feel the burning sensation and pain when the Lactate accumulates in the cell and experience oxygen debt.

ADVANTAGES AND DISADVANTAGES OF FERMENTATION
ADVANTAGES AND DISADVANTAGES OF FERMENTATION
ADVANTAGES
DISADVANTAGES
•All available energy extracted from Glucose is 2 ATPs. •Certain Bacteria produces chemicals of industrial importance such as isopropanol, butyric acid, acetic acid when bacteria ferment-breakdown of sugars in the absence of oxygen.
•The consumption of 2 ATPs are fast. •Glucose is partial to completely oxidized. •Ethanol and Lactate, the by-products of Fermentation, have a lot of. energy reserves — proka and Eukaryotes cannot extract energy in Lactate and ethanol using Anaerobic Method.
vs.
ADVANTAGES AND DISADVANTAGES OF FERMENTATION
ADVANTAGES
DISADVANTAGES
•Foods that are fermented last longer because these fermenting organisms have removed many of the nutrients that would attract other microorganisms. •It can improve your gut health, it tastes better, it can help you digest your food much easier.
•It can cause us to retain gas, or be bloated, due to the high percentage of Probiotics in fermented foods. •Fermentation needs a massive supply of Glucose to perform the same as in aerobic Respiration.

The Role of Oxygen
The Role of Oxygen
• Oxygen does play an essential role in Cellular, particularly in Aerobic respiration.
• Animals, Fungi, plants, and we humans do perform Aerobic Cellular Respiration to produce energy.
• It serves as the Final Electron acceptor in the Electron Transport Chain, where it is facilitating the movements of the electrons down this transporting chain, causing the ATPs to produce.
The Role of Oxygen
The Role of Oxygen
The Role of Oxygen
• Oxygen is used in the Inner Mitochondrial Membrane in the ETC to undergo Oxidative Phosphorylation.
• Oxygen allows the electrons to be transferred through the ETC, in order to create an Electro-chemical gradient for Hydrogens to produce ATP.
• In Photosynthesis, oxygen helps to break down glucose, where it releases energy and heat in the process.
