Discussion Overview

The discussion revolves around the role of ribosomes and lysosomes in cellular processes, particularly focusing on the presence of membranes and the function of enzymes in digesting unwanted structures within the cell. The scope includes conceptual clarification and technical explanation regarding cellular organelles and their interactions.

Discussion Character

  • Conceptual clarification
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants assert that ribosomes have a membrane to protect the cell from enzymes, questioning how cells remain undamaged during enzyme activity.
  • Others argue that ribosomes do not have membranes and can bind to membrane-bound structures, particularly in the endoplasmic reticulum.
  • A participant suggests that the discussion may be about lysosomes, which contain digestive enzymes that are not released into the cytoplasm but rather act within a phagolysosome formed through phagocytosis.
  • Clarifications are made regarding the process of phagocytosis and the formation of phagosomes and phagolysosomes, emphasizing the protective role of membranes in these processes.

Areas of Agreement / Disagreement

Participants express disagreement regarding the membrane presence of ribosomes, with some asserting they have membranes and others refuting this claim. The discussion remains unresolved as to the initial assertion about ribosomes and their protective role against enzymes.

Contextual Notes

There are limitations in the discussion regarding the definitions of ribosomes and lysosomes, as well as the mechanisms of enzyme action within the cell. Some assumptions about the roles of these organelles and their interactions with enzymes are not fully explored.

The ribosomes have a membrane to prevent damage of the cell from the enzyme. but why are the cells not damaged when the enzymes are digesting unwanted structures, since the enzymes have to be released to digest unwanted structures.

I'm not sure what you mean, ribosomes do not have membranes. They can bind to membrane bound (particularly in the endoplasmic reticulum).

I think you mean lysosomes. Yes the lysosomes have digestive enzymes but they aren't exactly released into the cytoplasm while destroying unwanted objects. Extra cellular material usually enters via phagocytosis, i.e. the material is gradually enclosed and then pinched off from the plasma membrane into the cytoplasm. This vacuole is called phagosome. The membrane of the lysosome fuses with that of the phagosome and forms a phagolysosome, the contents of which are then exposed to the enzymes and are eventually destroyed.
