Anaerobic respiration isa)Extramolecular respirationb)Molecular respirationc)Inter-molecular respirationd)Intra-molecular respirationCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

The anaerobic respiration takes place in organisms like yeast, some bacteria, and parasitic worms. ... For example, yeast is an organism which can live without the oxygen of air because it obtains energy by the process of anaerobic respiration...so it is  called Inter Molecular respiration......

Answer

Anaerobic respiration means that the respiration which occur in absence of oxygen . In human body mostly occur aerobic respiration but when we need extra energy then it is occurrence like, in muscles. so it is also known as intra- molecular respiration.

Answer

Anaerobic respiration is a metabolic process that occurs in the absence of oxygen. It is performed by some organisms, including certain bacteria and yeast, as well as by muscle cells during intense exercise when oxygen supply cannot meet the demand. This process allows these organisms to continue producing energy in the absence of oxygen, albeit at a lower efficiency compared to aerobic respiration.

Anaerobic respiration involves a series of biochemical reactions that take place within the cell. These reactions can be categorized as intramolecular respiration because they occur within the molecules of the cell. Let's explore this in more detail:

1. Intra-molecular respiration:
- Intra-molecular respiration refers to the metabolic reactions that occur within the molecules of the cell.
- Anaerobic respiration involves the breakdown of glucose, a simple sugar molecule, to produce energy.
- This process does not require the presence of oxygen and occurs in the cytoplasm of the cell.
- The first step of anaerobic respiration is called glycolysis, where glucose is converted into two molecules of pyruvate.
- Glycolysis is an intramolecular process as it occurs within the molecules of glucose and does not involve any external factors.

2. Comparison with aerobic respiration:
- In contrast to anaerobic respiration, aerobic respiration requires the presence of oxygen and occurs in the mitochondria of the cell.
- Aerobic respiration is a more efficient process and produces a higher yield of energy (in the form of ATP) compared to anaerobic respiration.
- It involves several intramolecular reactions, such as the Krebs cycle and the electron transport chain, which occur within the mitochondria.

3. Energy production and byproducts:
- In anaerobic respiration, glycolysis is followed by a series of reactions that convert pyruvate into different end products depending on the organism.
- In some organisms, like yeast, pyruvate is converted into ethanol and carbon dioxide, while in others, like bacteria, it is converted into lactic acid.
- These end products are waste products that need to be eliminated from the cell.

In conclusion, anaerobic respiration is a form of intramolecular respiration that occurs in the absence of oxygen. It involves the breakdown of glucose into energy through glycolysis and subsequent reactions. The process is less efficient than aerobic respiration and produces different end products depending on the organism.

Answer

Anaerobic respiration is the process of incomplete oxidation of organic molecules in the absence of molecular oxygen. It is Inter molecular respiration. There are sufficient reasons to believe that the first cell on the planet lived in an atmosphere that lacked oxygen. we know of the several that are adapted to anaerobic respiration.
