Q5. What are the main functions of each of the following components?
a) Plasma membrane
b) Mitochondria
c) Nucleus
d) Ribosomes
Answers
Answer:
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
what are the main functions of each of the following components:
1)plasma membrane
2) mitochondria
3) nucleus
4) ribosomes
the functions of the following components are:
1)plasma membrane
protective barrier
regulate transport in and out of cell(selectively permeable)
allow cell recognition
provide anchoring sites of filaments of cytoskeleton
2) mitochondria
production of ATP(energy)
regulation of immunity
calcium balance
cell death and renewal(autophagy)
stem cell regulation
3) nucleus
controls all the cellular functions
control the synthesis of structural proteins
contains genetic nformation for reproduction, development and behaviour
4) ribosomes
protein builders of the cell.
travel alongs RNA and cannect amino acids into polypeptides.
polyribosomes can make several polypeptides at the same time.
protein synthesis
intracellular digestion
transport of protein outside of the cell
