The lipids, specifically phospholipids of the CM is said to be (a)   in nature, meaning they have both hydrophobic and hydrophilic characteristics.

What year marked the discovery of the existence of plasma membrane?

(a)

Hugh Davson and James Fanielli (1935) : Sandwich Model : : Garth L. Nicolson (1972) : _____ ______ _____

(a)  

a lipid made of glycerol, two fatty acid tails and a phosphate-linked head group

(a)  

saturated fatty acids : solid : : unsaturated fatty acids : (a)  

a lipid whose structure is different from that of a phospholipid. it is composed of four fused carbon rings and found alongside phospholipids in the core of the membrane

(a)  

prevents the plasma membrane to become too fluid if the temperature rises or too solid if the temperature drops

(a)  

can be found on the outside surface of the cells

(a)  

carbohydrates that are bound to proteins

(a)  

carbohydrates that are bound to phospholipids

(a)  

proteins found on the membrane are called (a)   proteins; they may extend halfway into the cell membrane

proteins that cross the membrane ENTIRELY and are PERMANENTLY attached

(a)  

proteins that are LOOSELY attached to its inside or outside face; TEMPORARILY attached

(a)  

How much percent of the plasma membrane is composed of cholesterol and phospholipids? (ex. 80)

(a)  

How much percent of the plasma membrane is composed of carbohydrates? (ex. 60)

(a)  

Which membrane protein serves as a PATHWAY or is defined as a simple protein that forms a channel and allows substances to move across the membrane from one side to another

(a)  

What type of membrane protein is show in the picture?

(a)  

which membrane protein transport molecules by changing their shape to receive substances like sodium and potassium across the cell membrane?

(a)  

membrane protein that is defined as glycoproteins that help the body to recognize invading pathogens and initiate immune response; these are carbohydrates attached to proteins in cell membrane

(a)  

membrane proteins that have a specific shape that allows only a signaling molecule to bind it; used in coordinated cell response

(a)  

are membrane proteins needed by the cell to carry out metabolic reactions and maintain homeostasis; it SPEEDS UP the change of substances into other substances

(a)  

what kind of membrane protein shown in the picture?

(a)  

involved in forming various types of junctions (e.g. gap junctions) that allow signaling molecules to pass through)

(a)  

heat energy of the cellular

environment provides all of the energy; hence, this is not

energy costly to the cell

(a)  

requires the cell to do work, requiring

the cell to expend its energy reserves.

(a)  

happens when particles move from an area of high

concentration to an area of low concentration

(a)  

diffusion: solute and solvent moves : : (a)   : solvent moves

a process by

which molecules and ions are

transported from one location to

another with the aid of some

intermediary, such as the carrier

protein. The molecules are transported

from an area of higher concentration to

an area of lower concentration.

(a)  

a special type of

diffusion specifically associated

with the movement of water

molecules. The net movement of

water across a semi-permeable

membrane from an area of lower

solute concentration to an area of

higher solute concentration.

(a)  

the part of a solution that is being

dissolved (usually the lesser amount); usually solid

(a)  

the part of the solution that dissolves

the solute (usually the greater amount); usually liquid

(a)  

a combination of solute and solvent

(a)  

(also known as osmotic

concentration)- the total concentration of all

solutes in the solution

(a)  

Refers to how solute particles will

move through a gas or solution from

an area with a higher number of

particles to one with a lower number

of particles while being separated by

membrane

(a)  

a property of a solution that depends on the osmotic force

exerted across the membrane as influenced by the differing

concentrations of solutes in and out of the cell; the osmotic pressure

or tension of a solution, as in the cells would swell or shrink

depending on the tonicity of the environment

(a)  

the concentration of water is the same inside and outside of

the cell (in=out)

(a)  

the concentration of water is higher inside the cell than

outside (in> out)

(a)  

the concentration of water is higher outside the cell than

inside (in< out)

(a)  

is the movement of a

substance across a cell membrane

against its concentration gradient; the movement is

from low concentration to high

concentration, thereby needing

energy in the form of ATP (adenosine

triphosphate).

(a)  

type of tonicity present in animal cells

(a)  

type of tonicity present in plant cells

(a)  

transports substances

in a unidirectional manner

depending

(a)  

Antiporter transports

molecules in the SAME direction. true or false, write the correct answer if false.

(a)  

transports

molecules in opposite directions

(a)  

uses an electrochemical gradient

generated by active transport as

an energy source to move

molecules against their gradient
