Question

Identify the correct statement from the following.
A. Golgi apparatus is involved with the formation of lysosomes.
B. Nucleus, mitochondria and plastids have DNA; hence they are able to make their own
Structural proteins.
С. Mitochondria is said to be the powerhouse of the cell as ATP is generated in them.
D. All of the above.

Answer 1

Hint: A Golgi body, also known as a Golgi apparatus, is a cell organelle that assists in the processing and packaging of proteins and lipid molecules, especially those destined for cell export. The Golgi body is a set of stacked membranes named after its discoverer, Camillo Golgi. Since the nucleus, mitochondria, and plastid all have DNA, they can make structural proteins on their own.

Complete solution:
The Golgi apparatus is a collection of membranous stacks involved in the creation of lysosomes, which are suicidal bags of cells containing hydrolytic enzymes.
So, the statement in option A is right.
The nucleus, mitochondria, and plastids all have their own DNA, allowing transcription and translation to take place. As a result, they will make their own structural proteins.
So, the statement in option B is right
The process of protein synthesis in ribosomes is known as translation.
So, the statement in option C is correct.
Since it is the site of ATP synthesis, Mitochondria is known as the cell’s powerhouse. The Krebs’s cycle is a mechanism that produces ATP within mitochondria.
As a result, option D is correct.

Hence, Option D is the correct answer.

Note:
The genetic knowledge contained in DNA is a living database of instructions used by cells to carry out life's functions. Catalysts within each cell look for relevant information in this database and use it to create new proteins — proteins that make up the cell's structures, run its biochemical reactions, and are sometimes produced for export. Despite the fact that all cells in a multicellular organism have the same genetic information, functionally different cells within the organism use different sets of catalysts to express only particular portions of these instructions in order to carry out life's functions.
