Active Transport MECHANISMS

Question 1

Active transport pump

Answer 1

Moves a substance uphill ( from area of low concentration to an area of high concentration); requires an input of energy (ATP)

Question 2

Endocytosis

Answer 2

Taking in or ingestion of substances by the cell membrane

Question 3

Phagocytosis

Answer 3

Engulfing of solid particles by the cell membrane (cellular eating)

Question 4

Pinocytosis

Answer 4

Engulfing of liquid droplets (Cellular drinking)

Question 5

Exocytosis

Answer 5

Secretion of cellular products (protein,debris) out of the cell.
Ex-the cells of the pancreas make proteins for use outside of the pancreas.

Question 6

Active transport mechanisms require an input of energy in the form of

Answer 6

ATP

Question 7

Active transport mechanisms include :

Answer 7

• active transport pumps
• endocytosis
• exocytosis

Question 8

Two forms of endocytosis

1. ) if endocytosis involves solid particle
2. )if the cell ingests a water droplet

Answer 8

1. ) phagocytosis

2. ) pinocytosis
