Filtration

Question 3

List 3 types of active transport

Answer 3

Primary
Secondary (co-transport)
Endo/exocytosis

Question 4

Define isotonic

Answer 4

A solution with the same osmotic pressure as body fluids

Question 5

Define hypotonic

Answer 5

A solution with with lower osmotic pressure (WP) than bodily fluids is hypotonic

Question 6

Define hypertonic

Answer 6

A solution with higher osmotic pressure (WP) than bodily fluids

Question 7

Define Endocytosis

Answer 7

The process of actively transporting molecules into the cell by engulfing it with its membrane.

Question 8

Define exocytosis

Answer 8

the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane
