Q

Which of the the two makes up the majority of the membranes framework?

A

Phospholipids

16
Q

These proteins extend across the plasma membrane, helping to move substances in and out of the cell, acting as recognition sites for hormones, or serving as enzymes to speed reactions.

17
Q

These proteins are loosely attached to the surfaces of the cell membrane, serving as cytoskeleton anchors or cell identity markers.

A

Peripheral

18
Q

What do mean when we say the cell membrane maintains an electrochemical gradient?

A

Difference in change

19
Q

The movement of substances across a cell membrane using cellular energy (ATP)

20
Q

The movement of substances across a cell membrane using no cellular energy

21
Q

Net movement of any substance (such as cocoa powder in hot milk) from region of higher concentration to region of lower concentration; membrane not required

A

Simple diffusion

22
Q

Same as (a) except movement is across a semipermeable membrane with help of a carrier; ATP not required

A

Facilitated diffusion

23
Q

Net movement of water from region of high water concentration. (Such as 2% NaCl) to region of lower concentration (such as 10% NaCl) across semipermeable membrane: important in maintaining normal cell size and shapes

24
Q

Movement of molecules from high-pressure zone, as in response to force of blood-pressure.

A

Filtration

25
Q

A solution that is hypertonic to RBCs contains ____ solute particles and ____ water molecules than blood

A

More, fewer

26
Q

A solution that is ____-tonic to RBCs will maintain the size and shape of the RBC

A

Iso..isotonic
