Body fluid compartments

Question 1

The body fluids are found in two compartments

Answer 1

The extracellular fluids and intracellular fluid. They are in osmotic equilibrium but have very different chemical compositions

Question 2

The body compartments are in a state of dynamic

Answer 2

disequilibrium. The cell membrane is a selectively permeable barrier between the ECF and ICF

Question 3

List the two categories of membrane proteins and where they’re found

Answer 3

Integral proteins- found within the membrane. ex. Transmembranes
Peripheral proteins- Bound to inner or outer surface of the membrane

Question 4

Membrane proteins (6)

Answer 4

Receptor proteins
carrier proteins
channels,
anchoring porteins
recognition proteins (identifiers)
Enzymes

Question 5

Bind and respond to ligands (ions, hormones)

Answer 5

receptor proteins

Question 6

Transport specific solutes through membrane

Answer 6

carrier proteins

Question 7

Regulate water flow and solutes through membrane

Answer 7

Question 8

Attach to inside or outside structures

Answer 8

anchoring proteins (stabilizers)

Question 9

Label cells as normal or abnormal

Answer 9

Recognition proteins (identifiers)

Question 10

Catalyze reactions

Answer 10

enzymes

Question 12

Is 1/3 of the total body water volume.

Answer 12
