D10 ribosomes

Question 1

What are ribosomes?

Answer 1

Small, dense organelles that are found in the cytoplasm of cells or attached to Rough Endoplasmic Recticulum

They are small in prokaryotic cells (70s) than eukaryotic cells (80s)

Question 2

What are the two types of ribosomes?

Answer 2

Larger 80s type ribosomes found in Eukaryotic cells

Smaller 70s type ribosomes - found in Prokaryotic cells

Question 3

Where are ribosomes found?

Answer 3

Rough endoplasmic reticulum (proteins)

Free cytoplasm (Enzymes)

Question 4

Where are ribosomes manufactured?

Answer 4

Nucleolus from ribosomal RNA and protein

Question 5

What is the function of ribosomes

Answer 5

Ribosomes are important in protein synthesis as they are the site of translation, where mRNA is used to assemble the polypeptide chain

Question 6

Overview for longer answers

Answer 6

A ribosome is a small dense organelle found in large number in both prokaryotic and eukaryotic cells

The ribosomes found in prokaryotic cells are smaller (70s) than those found in Eukaryotic cells (80s)

Ribosomes are formed in the Nucleolus from RNA and Protein

The play an important part in protein synthesis as they are the site of translation, where mRNA is used to assemble polypeptide chains.
