amount of a
given substance
contained within
a solution or in a
particular volume
of space
LOW
CONCENTRATION
HIGH
CONCENTRATION
Passive Transport
• Materials move from
high  low concentration
• NO ENERGY NEEDED
When does passive transport stop?
• Occurs until concentration
becomes EQUAL on both sides
(EQUILIBRIUM)
Explain why this diagram
represents passive transport.
Weeee!!!

represents passive transport.
LOW
HIGH
+ energy
1. Identify the high and low

Support your answer.
Active Transport
• Movement of materials from
LOW  HIGH concentration
• ENERGY IS NEEDED!
Exit Card…
Compare and contrast passive and active transport
by completing one of the following.
Write a paragraph of at least 4 sentences comparing
and contrasting passive and active transport. Be sure
to use the following terms: particles, energy, high
concentration, low concentration.
OR
Compare and contrast passive and active transport by
drawing diagrams of each type. Be sure to label the
particles, high concentration, low concentration,
energy. Draw an arrow showing the movement of the
particles.

Example of
substance(s)
that use this
kind of
transport in
cells
During the process of respiration, energy
from the breakdown of glucose is
stored in molecules of
(1.) DNA
(2.) ADP
(3.) ATP
(4.) RNA
In the presence of oxygen, _____
molecules of ATP can be formed.
(1.)2
(2.) 19
(3.) 36
(4.) 63

(2.) aerobic respiration
(3.) anaerobic respiration
(4.) chemosynthesis
The net yield of ATP from the
process of fermentation is
(1.) 2
(2.) 4
(3.) 34
(4.) 36
Muscles cells engaged in vigorous
activity build up relatively high
concentrations of
(1.) lactic acid
(2.) pyruvic acid
(3.) alcohol
(4.) oxygen
Where do the final stages of cellular
respiration appear to take place?
(1.) along the endoplasmic reticulum
(2.) in the cytoplasm
(3.) on the surface of ribosomes
(4.) within the mitochondria
Aerobic respiration and fermentation
are similar in that BOTH processes
(1.) require oxygen
(2.) use light energy
(3.) release energy
(4.) produce glucose
During aerobic respiration, the chemical
energy of a glucose molecule is
gradually released, producing 36 ATP
and
(1.) NH3 and O2
(2.) NH3 and CO2
(3.) H2O and O2
(4.) H20 and CO2
TRUE OR FALSE
1. Respiration is when structures and organs
move oxygen into the body and waste gases
out of the body.
2. Breathing can help respiration when its
waste gases move out of the body.
3. Respiration is the chemical reaction that
happens when oxygen delivered to the cells is
used to release energy from glucose.
4. So when you breathe out you are using cell
respiration.
5. Respiration spreads necessary items into
cells that need it.
6. Breathing is the movement of the chest that
brings air into the lungs and removes gas.
7. Respiration is the process when CO2 and
H2O molecules are carried back to the lungs in
the blood.
8. Respiration is when oxygen is being
transported to your cells.
9. Cellular respiration is the part of breathing
that removes CO2 and H2O molecules.
10. We inhale air containing waste products.
11. Breathing is a voluntary process while
respiration is an involuntary process.
