The correct answer is peroxisomes.  

Peroxisome refers to a small organelle found in the cytoplasm of various cells that comprises catalase (the reducing enzyme) and generally some oxidases.  

They are the minute vesicles and comprises the digestive enzymes used for dissociating toxic components in the cell. They are not similar to lysosomes on the basis of the kind of enzymes they withheld. The peroxisomes generally contain enzymes that need oxygen, that is, oxidative enzymes.

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.
