In cells, proteins are synthesised in _______.

The correct answer is Ribosome. 

Key Points

• Ribosomes:-
  • They are complex molecular machines composed of RNA and protein molecules.
  • They exist in all living cells, from bacteria to eukaryotes, and are essential for protein synthesis.
  • The primary function of ribosomes is to synthesize proteins through a process called translation.
  • They read the genetic information encoded in mRNA (messenger RNA) and use it to assemble amino acids in the correct order to form a protein chain.

Additional Information

•  Mitochondria:-
  • Mitochondria are double-membraned organelles found in the cells of eukaryotic organisms.
  • They have an outer membrane and an inner membrane that encloses the mitochondrial matrix.
  • The inner membrane is highly folded into structures called cristae, which increase its surface area for energy production.
  • One of the primary functions of mitochondria is to generate energy through aerobic respiration.
  • This process involves the conversion of nutrients, particularly glucose, into adenosine triphosphate (ATP), which is the cell's primary energy currency.
  • This process occurs in the mitochondria's inner membrane, specifically in the cristae.
• Golgi apparatus:-
  • It is also known as the Golgi complex or Golgi body
  • It is a membranous organelle found in eukaryotic cells.
  • It consists of a series of flattened membrane-bound sacs or cisternae arranged in stacks, along with associated vesicles.
• Nucleus:-
  • It is a membrane-bound organelle found in eukaryotic cells.
  • It contains the cell's genetic material, including DNA, and serves as the control center of the cell. 
  • The nucleus is typically spherical and surrounded by a double-layered membrane known as the nuclear envelope.
