What are the functions of mitochondria, Nucleus, Endoplasmic Reticulum and ribosome?

Functions of Mitochondria:

*Powerhouse of the cell.

*Food stuffs broken down in cytoplasm converted to useable energy “currency” called ATP.

*Inner membrane contains “respiratory” enzymes.

*To help the production sperm & ovum.

*Fat metabolism.

*To product some DNA & RNA.

Functions of Nucleus:

*It produces Ribosome.

*Synthesis RNA & Protein.

*The DNA also inherits the character to the offspring through genes.

*It influences growth and initiates divisions or reproduction of cell.

Functions of Endoplasmic reticulum:

*Transport, storage, packaging of materials

*Surface area for cellular reactions

*Granular ER – Synthesis of proteins bound for secretion

*A granular ER-

      a. Storage area for Ca++ (muscle Cells)

     b. Lipid synthesis inactivation

    c. Detoxification of harmful compounds

Functions of Ribosome:

*Only site of protein synthesis

*”Read” the messenger RNA sent out from uncles

*Free ribosome – scattered throughout cytoplasm

*Attached ribosome – found on endoplasmic reticulum
