Cells

Question 1

Function of nucleus

Answer 1

Stores DNA

Question 2

Function of ribosomes

Answer 2

Makes protein

Question 3

Function of Soft ER

Answer 3

Makes lipids , detoxifies cell

Question 4

Function of lysosome

Answer 4

Contains hydrolytic enzymes to break down macromolecules ( proteins, lipids , carbohydrates, nucleotides)

Question 5

Function rough ER

Answer 5

Proteins travel through golgi

Question 6

Function of golgi

Answer 6

Receives lipids / proteins , modifies ( add sugar ) and ships them out of the cell

Question 7

Compare / contrast Simple and facilitated diffusion

Answer 7

No ATP needed move from high to low concentration of solute butch nice substances across the membrane

Question 8

What way will water move

Answer 8

Water goes in water always travels from high to low concentration solute

Question 9

Osmosis

Answer 9

Movement of water, moves across membrane , moves from high concentration to low concentration of water

Question 10

Isotonic solution

Answer 10

The concentration of solute is the same inside and outfitter the cell

Question 11

Hypertonic

Answer 11

The concentration of the solution is higher outside the cell

Question 12

Hypotonic

Answer 12

The concentration of solution is lower outside cell : water enters

Question 13

Exocytosis

Answer 13

Using ATP to allow large substances to leave the cell

Question 14

Endocytosis

Answer 14

Using ATP to allow substances to enter cell

Question 15

Pinocytosis

Answer 15

Small molecules ( lots ) or liquids-see above , but smaller and without lysomes

Question 16

Receptor

Answer 16

Mediated endocytosis - bring specific molecules into cell
