Specialized structures that perform cell functions are ? a. organelles b. animal cells c. plant cells d. prokaryotes
Fed [463]

Specialized structures that perform cell functions are organelles.

What are cell organelles?

An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.

An organelle is a particular sort of cell structure. Organelles come in many different varieties. Vesicles are another name for organelles in a cell. They actually serve a purpose that is crucial since all of the processes in a cell must be compartmentalized. Therefore, a membrane is required to surround the processes inside a cell that produce diverse products. Organelles are therefore all membrane-bound in reality. They also distinguish between one function and another. So, for instance, the lysosome breaks down large molecules to make small molecules, while the mitochondrion produces energy by breaking down large molecules.

They must be divided up since the lysosome requires an acidic pH and the mitochondrion relies on all of its pathways, proteins, and enzymes to convert one chemical to another. Additionally, none of the functions would be created if those two substances were combined.

xz_007 [3.2K]

Answer:

frontal

Explanation:

  • In a mammalian brain, there are four major lobes that are present and one of them is the frontal lobe.
  • The frontal lobe is mainly rich in dopaminergic neurons and thus, it is mainly concerned with functions such as memory, reward, motivation, planning, attention, etc.
  • The process of break down of tissues and cell death in the tissues is referred to as atrophy and since the frontal lobe is associated with the functions as mentioned above its atrophy would lead to a slow decline in these functions.
  • Since Mr. Klondlike behavior is changing his blunt comments are most likely a result of atrophy of the frontal lobe.
