Question

How is ATP Produced in Prokaryotic Cells?

Answer 1

Hint: ATP, or adenosine triphosphate, is a molecule that transports energy within cells. It is the cell's primary source of energy, and it is produced by photophosphorylation (adding a phosphate group to a molecule using light energy), cellular respiration, and fermentation.

Complete answer:
Single-celled microorganisms known as prokaryotic cells are the oldest on the planet. Bacteria and Archaea are examples of prokaryotes. Cyanobacteria, which perform photosynthesis, are among the photosynthetic prokaryotes.
Because a prokaryotic cell has only one membrane, all reactions take place within the cytoplasm. They can be parasitic or free-living.
Characteristics of prokaryotic cells:
They are devoid of a nuclear membrane.
There are no mitochondria, Golgi bodies, chloroplasts, or lysosomes.
A single chromosome contains all of the genetic material.
Histone proteins, which are essential components of eukaryotic chromosomes, are missing.
Carbohydrates and amino acids make up the cell wall.
The plasma membrane serves as the respiratory enzyme-carrying mitochondrial membrane.
Binary fission is used to divide them asexually. Conjugation is the sexual mode of reproduction.
Mitochondria, the main site of ATP synthesis via the electron transport system, are absent in prokaryotic cells. The cell membrane of prokaryotic cells contains enzymes required for ATP synthesis.
The electron transport chain is a set of four protein complexes that link redox reactions to create an electrochemical gradient that results in the production of ATP in a process known as oxidative phosphorylation. In both cellular respiration and photosynthesis, it occurs in mitochondria.

Thus, ATP is Produced in Prokaryotic Cells by using the electron transport system.

Note:
Eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways such as photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation, starting with energy sources obtained from their environment in the form of sunlight and organic food molecules.
