M4 - Membrane-bound Organelles (P1)

Question 1

Largest organelle, accounting for ~10% of the cell’s volume

Answer 1

Nucleus

Question 2

Contains the genome and through gene expression, coordinates cell activities

Answer 2

Nucleus

Question 3

Consists of nuclear envelope, chromatin, and nucleolus

Answer 3

Nucleus

Question 4

Major site of synthesis in the cell / is the site of ATP synthesis for the cell

Answer 4

Endoplasmic Reticulum

Question 5

Flattened sac network (cisternae) that is continuous with the outer nuclear membrane

Answer 5

Endoplasmic Reticulum

Question 6

Has a part which takes proteins from the cytosol and continues its production in the golgi apparatus until completion

Answer 6

Endoplasmic Reticulum (Part: Rough ER)

Question 7

Responsible for packaging of macromolecules into vesicles so that is can be sent out to their site of action

Answer 7

Golgi apparatus

Question 8

Modifies proteins and lipids which are obtained from the endoplasmic reticulum

Answer 8

Golgi apparatus

Question 9

Has inner and outer membrane with an intermembrane space in between

Answer 9

Mitochondria

Question 10

Outer membrane contains proteins known as porins that enable ion movement to and from mitochondrion

Answer 10

Mitochondria

Question 11

Inner membrane includes a number of enzymes such as ATP synthase that produces ATP in the matrix and carries proteins that control metabolic movement into and out of the matrix

Answer 11

Mitochondria

Question 12

Arranged in cristae in order to increase the surface area available for energy production

Answer 12

Mitochondria

Question 13

Help maintain the intracellular environment as it stores caspases responsible for triggering apoptosis and able to transiently store calcium contributing to calcium homeostasis

Answer 13

Mitochondria

Question 14

Powerhouse of the cell

Answer 14

Mitochondria

Question 15

Acidic membrane-bound organelle that contain numerous hydrolytic enzymes which catalyze hydrolysis reactions

Answer 15

Lysosomes

Question 16

The membrane that surrounds this is important for ensuring that these enzymes do not flow into the cytoplasm and destroy the cell from within

Answer 16

Lysosomes
