it stores nutrients, ions, and water.

Answer 2

Animal cell’s vacuole

Question 3

the sites of ATP Synthesis.

Answer 3

Chloroplast and Mitochondria

Question 4

what is the main function of the endomembrane system?

Answer 4

synthesis and modification of proteins and lipids

Question 5

is a group of organs that work together to perform certain tasks.

Answer 5

Biological System (Organ System or Body System)

Question 6

the biological system requires what?

Answer 6

buffers (molecules that donate or accept protons to resist drastic change in PH)

Question 7

metabolic reactions will not proceed without?

Answer 7

enzymes (are catalysts of biological reactions)

Question 8

are type of lipids that are biological component of plasma membranes.

Answer 8

Phospholipids

Question 9

is the type of transport system that requires an energy to move molecules from lower to higher concentration.

Answer 9

Active Transport

Question 10

this type of transport system does not require energy.

Answer 10

Passive Transport

Question 11

is the movement of water molecules through plasma membrane from a region of low concetraion to a region of high concentration.

Answer 11

Osmosis

Question 12

is the passive movement of particles from a region in which they are in higher concentration to regions of lower concentration.

Answer 12

Diffusion

Question 13

is a process by which substances are transported across cell membranes by means of proteins carrier molecules.

Answer 13

Facilitated Diffusion

Question 14

is the number of particles per unit volume.

Answer 14

Concentration

Question 15

what happens to the carrier in facilitated diffusion?

Answer 15

The carrier changes its shape while the channel creates a path.

Question 16

is the end of the organelle where substances enter from the endoplasmic reticulum for processing.

Answer 16

Cis Face

Question 17

is where they exit in the form of smaller detached vesicles.

Answer 17

Trans Face

Question 18

the most acceptable cell membrane model.

Answer 18

Fluid Mosaic Model

Question 19

they published “The fluid mosaic model of the structure of cell membranes” in 1972.

Answer 19

Syemour Jonathan Singer and Garth L. Nicolson

Question 20

describes how an extracellular solution can change the volume of a cell by affecting osmosis.

Answer 20

Tonicity

Question 21

the difference between the amounts of molecules present at two points, which determines the movement of molecules
(HIGH TO LOW)

Answer 21

Concentration Gradient

Question 22

describes the total solute concentration of the solution.

Answer 22

Osmolarity

Question 23

A solution with “____” has a greater number of water molecules relative to the number of solute particles

Answer 23

Low Osmolarity

Question 24

A solution with “____” has fewer water molecules with respect to solute particles

Answer 24

High Osmolarity

Question 25

In this solution, the extracellular fluid has the same osmolarity as the cell, thus there will be no net movement.

Answer 25

Isotonic Solution

Question 26

In this solution, the extracellular fluid has lower osmolarity than the fluid inside the cell, and water enters the cell.

Answer 26

Hypotonic Solution

Question 27

In this solution, the extracellular fluid has a higher osmolarity than the cell’s cytoplasm; therefore, the fluid contains less water than the cell does. (water will leave the cell).

Answer 27

Hypertonic Solution

Question 28

a type of transport proteins that are embedded in the cell membrane & have a pore for materials to cross.

Answer 28

Channel Proteins

Question 29

can change shape to move material from one side of the membrane to the other

Answer 29

Carrier Proteins

Question 30

Macromolecules, like proteins and other large particles, cannot enter and exit the cell through carrier proteins. They enter or leave the cell in a different process that also requires energy.

Answer 30

Bulk Transport

Question 31

A type of bulk transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell.

Answer 31

Endocytosis

Question 32

is the process by which large particles, such as cells or relatively large particles, are taken in by a cell.

Answer 32

Phagocytosis (Endocytosis)

Question 33

This is a process that takes in molecules, including water, which the cell needs from the extracellular fluid.

Answer 33

Pinocytosis (Endocystosis)

Question 34

This is a process where the plasma membrane becomes indented and forms a pit. The pit lined with receptor proteins picks specific molecules from the surroundings. The pit will close and pinch off to form a vesicle, which will carry the molecules inside the cytoplasm.

Answer 34

Receptor-mediated (Endocystosis)

Question 35

A type of bulk tranposrt in which materials for export like proteins produced in the ribosomes and packaged in the Golgi body are secreted out of the cell

Answer 35

Exocytosis
