Question

Ribosomes are associated with the synthesis of
A: Proteins
B: Fat
C: Carbohydrates
D: All of the above

Answer 1

Hint: Both prokaryotic and eukaryotic cells contain ribosomes, which are specialised cell organelles. Ribosomes are required for the production of proteins in every living cell.
Binding to a messenger RNA (mRNA) and decoding the knowledge carried by the mRNA's nucleotide sequence also are functions of this cell organelle.
At the acceptor site, transfer RNAs (tRNAs) containing amino acids join the ribosome. It binds to tRNA and adds amino acids to the increasing protein chain.

Complete answer:
Option A:
Ribosomes are organelles that aid within the production of proteins. Many cellular functions, such as damage repair and other chemical processes, need protein. During protein synthesis, the ribosomal subunits come together and combine with the mRNA. They bind to the mRNA and initiate protein synthesis.
So, option A is correct.
Option B:
Fatty acid synthesis is the process of producing fatty acids from acetyl-CoA and NADPH using enzymes known as fatty acid synthases. The cytoplasm of the cell is where this happens. The glycolytic pathway generates the majority of the acetyl-CoA that is converted into fatty acids.
So, Option b is incorrect.
Option C:
Carbohydrates are produced by green plants during the photosynthesis process from carbon dioxide and water. Carbohydrates are energy sources and structural elements in organisms; carbohydrate also makes up part of the structure of nucleic acids, which include genetic material.
So, option C is incorrect.
Option D:
In the process of protein synthesis or translation, a ribosome is a complex molecular machine located within living cells that produces proteins from amino acids. Protein synthesis is a fundamental activity that all living cells must carry out.
So, option D is incorrect.

Hence, Option A is the correct answer.

Note:
A ribosome is a ribonucleoprotein, which means it is made up of RNA and protein. It is made up of two subunits, one smaller and the other larger. The mRNA binds and is decoded in the smaller subunit, while the amino acids are inserted in the larger subunit. Protein and ribonucleic acid are also present in both subunits. In the process of protein synthesis or translation, a ribosome is a complex molecular machine located within living cells that produces proteins from amino acids. Protein synthesis is a fundamental activity that all living cells must carry out.
