Inclusion
13
List threes principle parts of a generalized animal cell.
Plasma membrane, cytoplasm, nucleus
14
Name the two major types of molecules that make up the plasma membrane.
Phosphorus & proteins
15
Which of the the two makes up the majority of the membranes framework?
Phospholipids
16
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.
Integral
17
These proteins are loosely attached to the surfaces of the cell membrane, serving as cytoskeleton anchors or cell identity markers.
Peripheral
18
What do mean when we say the cell membrane maintains an electrochemical gradient?
Difference in change
19
The movement of substances across a cell membrane using cellular energy (ATP)
Active
20
The movement of substances across a cell membrane using no cellular energy
Passive
21
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
Simple diffusion
22
Same as (a) except movement is across a semipermeable membrane with help of a carrier; ATP not required
Facilitated diffusion
23
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
Osmosis
24
Movement of molecules from high-pressure zone, as in response to force of blood-pressure.
Filtration
25
A solution that is hypertonic to RBCs contains ____ solute particles and ____ water molecules than blood
More, fewer
