Unit 3

Question 1

Cellular Respiration Equation

Answer 1

C6H12O6 + 6 O2 —> 6 CO2 + 6 H2O

Question 2

Concentration

Answer 2

the number of particles
per volume

Question 3

Concentration Gradient

Answer 3

differences in
concentrations across space

Question 4

Diffusion

Answer 4

the process by which particles
move from an area of high concentration to an
area of low concentration.

Question 5

Equilibrium

Answer 5

when movement in one direction is
matched by movement in the opposite direction yielding
no net movement.

Question 6

Permeable

Answer 6

membrane that allows a
particular substance to pass through it

Question 7

Impermeable

Answer 7

a membrane that does not
allow a particular substance to pass

Question 8

Semi-permeable

Answer 8

a membrane that
allows some things to cross but not others

Question 9

Osmosis

Answer 9

the diffusion of water
- Movement of water across a semi-permeable membrane from a region of high concentration to a region of low concentration

Question 10

Isotonic

Answer 10

the concentration is the same
on both sides of the membrane

Question 11

Hypertonic

Answer 11

the concentration is higher
on the outside of the cell

Question 12

Hypotonic

Answer 12

the concentration is lower on
the outside of the cell

Question 13

Passive Transport

Answer 13

Diffusion with concentration
gradient (no energy cost)

Question 14

Simple Diffusion

Answer 14

does not
require a channel
( no transport proteins involved)

Question 15

Facilitated Diffusion

Answer 15

requires a
protein to provide a pathway

Question 16

Active Transport

Answer 16

– movement requiring ATP
a) Going against the concentration gradient
b) Going faster than it would normally

Question 17

Exocytosis

Answer 17

The cell pushes something
out by sending a vesicle to the cell
membrane and having the vesicle fuse
with the cell membrane dumping its
contents outside.

Question 18

Endocytosis

Answer 18

Cell pulls something inside
by wrapping membrane around it.

Question 19

Phagocytosis

Answer 19

Endocytosis of solid particles

Question 20

Pinocytosis

Answer 20

Endocytosis of liquid

Question 21

Glycolysis

Answer 21

In the cytoplasm
To break sugar
2 ATP
(Splits glucose into 2 pyruvate)

Question 22

Krebs Cycle

Answer 22

In the matrix
Strips the H+ off of the parts of glucose - makes NADH
2 ATP

Question 23

Electron transport chain

Answer 23

Cristae
Makes H+ gradient and uses it to make ATP
34 ATP

Question 24

Photosynthesis equation

Answer 24

6 CO2 + 6 H2O —> C6H12O6 + 6 O2

Question 25

Light dependent

Answer 25

Thylakoid/Grana
Makes H+ gradient
Uses H+ gradient to make ATP

Question 26

Light independent

Answer 26

Stroma
Essentially uses the ATP to make sugar
Uses ATP and NADPH to join CO2 into glucose
