Names and functions of organelles

Question 1

Nucleus

Answer 1

Stores and replicates genetic material
Site of transcription
Houses the nucleolus

Question 2

Nucleolus

Answer 2

Production of rRNA and ribosomes

Question 3

Rough Endoplasmic Reticulum

Answer 3

Synthesis of secretory and membrane proteins
Site of post-translational modifications (occurs within rER lumen)
Checking and destruction of misfolded proteins by ubiquitination
Assembly of multichain proteins

Question 4

Smooth Endoplasmic Reticulum

Answer 4

Lipid synthesis
Steroid synthesis
Degradation of toxins and drugs
Stores calcium

Question 5

Golgi Complex

Answer 5

Processing station for proteins
Targets newly formed proteins to the appropriate subcellular areas
Further modifications also available

Question 6

Mitochondria

Answer 6

Powerhouse of the cell (ATP manufacturing)

Question 7

Lysosome

Answer 7

Digestive organelle that breaks down cellular debris

Question 8

Ribosomes

Answer 8

Synthesized in the nucleolus
They read mRNA code
Assemble AAs provided by tRNA, following the code, to produce peptides

Question 9

Proteasomes

Answer 9

Recognize ubiquitin-labeled proteins tagged by RER and degrades them

Question 10

Peroxisomes

Answer 10

Catalase in peroxisome breaks down H2O2
Peroxisomes are involved with drug and fatty acid metabolism (THINK IF YOU WANT TO GET RID OF OIL STAIN U USE H2O2)
