EXAM 2 Osmosis And Membranes

Question 1

Ion channel

Answer 1

Created passageway that allows ions through

Question 2

Uniporter

Answer 2

Membrane transport protein moves ion across in 1 direction

Question 3

Symporter

Answer 3

Transport protein moved two or more different types of ions across membrane

Question 4

Anti porter

Answer 4

Transmembrane protein transporting two or more different ions in opposite directions

Question 5

Glycosylation

Answer 5

process of adding sugar chains (glycans) to proteins or lipids, which occurs on the outside surface of the cell membrane

Question 6

Describe sugars added to glycosylate

Answer 6

The sugar chains are polar and perform new functions

Question 7

Process of glycosylation

Answer 7

1) Insert protein into ER
2) Sugar chain added
3) Attach sugar
4) Glyco-protein stays in membrane

5) Ship: ER → Golgi → vesicle → joins cell membrane
