Unit 4: Cellular Processes - Entry & Exit Tickets

Question 1

What materials do animal cells need to move into the cell?

Answer 1

Water, oxygen, proteins imported from other cells, and nutrients

Question 2

Selectively permeable structures do what?

Answer 2

Allow some materials in or out of the cell.

Question 3

The cell membrane is composed of which macromolecues?

Answer 3

Proteins, lipids, carbohydrates

Question 4

What cell membrane protein allowed the white blood cells to find and destroy the bacteria?

Answer 4

Glycoproteins

Question 5

Why was the WBC able to surround and ingest the bacteria?

Answer 5

The cell membrane is fluid and movable, cholesterol molecules in the cell membrane allowed for the fluid mosaic

Question 6

How do plasma membranes affect homeostasis?

Answer 6

Allowing messages and enzymes to cause the cell functions to change, allowing materials to pass through the membrane

Question 7

Attachment

Answer 7

Connect cytoskeleton to extracellular matrix

Question 8

Receptor

Answer 8

Causes a change inside of the cell due to signal transduction

Question 9

Junction

Answer 9

Binds cells to other cells

Question 10

Transport

Answer 10

Allows polar molecules to cross the membrane

Question 11

Enzyme

Answer 11

Causes a sequential reaction to occur

Question 12

Glycoprotein

Answer 12

Identifies the cell, organ, or individual; has attached carbohydrate chain

Question 13

What cell membrane proteins would a WBC use to identify a bacteria as foreign?

Answer 13

Glycoprotein

Question 14

What two features of the cell membrane allowed the WBC to fold around the bacteria and engulf and destroy it?

Answer 14

Fluid mosaic, cholesterol makes the bilayer movable

Question 15

Remembering the polarity of the cell membrane, which molecules would require transport molecules to cross a membrane?

Answer 15

Amino acids (polar), polysaccharides (large), and water (polar)

Question 16

Molecules moving from high to low concentration use what kind of transport?

Answer 16

Passive

Question 17

Endo and exocytosis require what item?

Answer 17

Energy

Question 18

Receives and transmits signals into a cell

Answer 18

Receptor

Question 19

Holds the cell in place connecting the cytoplasm to the extracellular matrix

Answer 19

Attachment

Question 20

Causes a chemical reaction to occur and lowers activation energy

Answer 20

Enzyme

Question 21

Joins two adjoining cells

Answer 21

Junction

Question 22

Identifies a cell as part of an organ, tissue, or greater organsim

Answer 22

Glycoproteins

Question 23

Helps move polar or large molecules across the membrane

Answer 23

Transport

Question 24

Solute

Answer 24

Dissolved in the Solvent

Question 25

Solvent

Answer 25

What dissolves the solute
