Topic 3 - Voice of the Genome

Question 1

Smooth ER

Answer 1

Similar to rough ER but without the ribosomes. Used for synthesis and to process lipids

Question 2

Rough ER

Answer 2

A system of membranes enclosing a fluid filled space. Folds and processes proteins that have been made at the ribosomes

Question 3

Lysosome

Answer 3

Contains digestive enzymes. Used to break down work out components of the cell

Question 4

Mitochondrion

Answer 4

Double bound membrane. Inner membrane is folded to form cristae and inside that is the matrix. Contains enzymes needed for respiration and is where ATP is produced

Question 5

Golgi apparatus

Answer 5

Fluid filled flattened sacs. It processes and packages new lipids and proteins. Makes lysosomes.

Question 6

Nucleus

Answer 6

A large organelle surrounded by a nuclear envelope which contains nuclear pores.

• contains chromatin (made of protein and DNA)
• the pores allow substances to move between the nucleus and the cytoplasm

Question 7

Centriole (?)

Answer 7

Hollow cylinders containing a ring of microtubules. Help with the separation of chromosomes during cell division.

Question 8

Ribosome

Answer 8

Small organelle that floats free in the cytoplasm.

• the site where proteins are made
• made of protein and RNA
