Membranous organelles: Mitochondria, E.R., Golgi Apparatus

What surrounds the mitochondria? (1)

A double membrane

Why is the mitochondria considered the powerhouse of the cell? (1)

It works to produce ATP which is the main source of energy for cells

What does the mitochondria contain? (4)

• DNA

• RNA

• proteins

• water

What is the Endoplasmic Reticulum? (1)

A network of membranous tubes

What is the function of the endoplasmic reticulum? (1)

Transport

What makes the Rough Endoplasmic look “rough”? (1)

Has ribosomes attached to its surface

What do the ribosomes on the Rough ER do? (1)

Synthesize certain proteins

Why does the Smooth ER appear “smooth”? (1)

Has no ribosomes attached to its surface

What is the function of the smooth ER? (3)

• Store Calcium

• Detoxify drugs and alcohol

• Synthesize lipids

What does the Golgi Apparatus look like? (1)

Stacks of membranous disks

What does the Golgi Apparatus do? (1)

Modify newly synthesized proteins by adding carbohydrate group forming glycoprotein

What does the Golgi Apparatus do with these glycoproteins? (4)

Package them into vesicles to transport them to:

• Cell membrane

• Lysosomes

• Secreted to Extracellular environment
