A1 Cells

Question 1

Function of mitochondria

Answer 1

Aerobic respiration
OR
Release energy
OR
Produce ATP

Question 2

Function of Golgi body

Answer 2

Modifies protein

eg adds carbohydrate to protein to make a glycoprotein

Question 3

Function of a ribosome

Answer 3

Translation

Protein synthesis

Question 4

Function of rough endoplasmic reticulum

Answer 4

Make and transport proteins around the cell

Question 5

Function of smooth endoplasmic reticulum

Answer 5

Make and transport lipids and steroids around the cell

Question 6

Function of the nucleus

Answer 6

Controls the activity of the cell

Question 7

Function of the nucleolus

Answer 7

Makes ribosomes

Question 8

Plasma/cell membrane

Answer 8

Controls which substances can cross a membrane
Controls which substances can enter and leave the cell

Question 9

What is the nuclear envelope and what is its function?

Answer 9

Double membrane surrounding the DNA (nucleoplasm)

Has pores in membrane to allow mRNA to leave the nuclues

Confines the genetic material (DNA) in the nucleus

Question 10

Human cells are eukaryotic or prokaryotic?

Answer 10

Eukaryotic

Question 11

Which organelles are involved in the production of a glycoprotein?

Answer 11

Ribosome (to make the protein)

Mitochondria (to supply the ATP to join the amino acids together)

Golgi apparatus (to modify the protein)
