and active transport.

Review:
Which process requires cellular
energy?
1. diffusion
2. passive transport
3. active transport
4. osmosis
Sodium ions are pumped from a region
of lower concentration to a region of
higher concentration in the nerve
cells of humans. This process is an
example of
1. diffusion
2. osmosis
3. passive transport 4. active transport
The movement of materials from
higher to lower concentration
is called
1. diffusion 2. active transport
3. pinocytosis 4. phagocytosis
Damage to which structure will most
directly disrupt water balance
within a single-celled organism?
1. ribosome
2. cell membrane
3. nucleus
4. chloroplast
Cell
• Glucose (sugar) is
Respiration broken down to make
ENERGY (ATP)
• Occurs in mitochondria
• Carried out by every
living thing!!!
• Oxygen (O2) required
Aerobic
Respiration to make energy
Oxygen
Carbon dioxide
& water vapor
EQUATION
C6H12O6 +
6O2  6CO2 + 6H2O + 36ATP
GLUCOSE + OXYGEN  CARBON + WATER + ENERGY
DIOXIDE
WASTES
(breathe out)
Anaerobic • Energy produced
Respiration WITHOUT oxygen
• FERMENTATION
• Occurs in the cytoplasm
EQUATION
C6H12O6  6CO2 + 2ATP
GLUCOSE
 CARBON
DIOXIDE

Do Now: (Take out your flippy cards)
1. Identify what is produced during aerobic
respiration. Anaerobic respiration?
2. Identify what is produced during aerobic
respiration. Anaerobic respiration?
HW: Bring in Science Board Wednesday or
Monday!
Aerobic respiration
Anaerobic respiration
2 types:
1. ALCOHOLIC
FERMENTATION =
– In yeast cells
• C6H12O6alcohol + CO2+2ATP
2. LACTIC ACID FERMENTATION =
– In your muscles, when oxygen is not
available
• C6H12O6  lactic acid + 2ATP
Let’s summarize…
1. Explain why the process of respiration is so
important.
2. Explain the difference between the two types
of respiration.
3. What nutrient is used in both types of
respiration?
4. Which type of respiration is more efficient?
Which statement is not a part of the cell
theory?

living things.
(2) Cells are the basic unit of function of
living things.
(3) Cell parts such as chloroplasts are selfreplicating.
(4) Cells come from preexisting cells.
Which structure permits the entry
and exit of materials in an animal
cell?
1. lysosome 2. chromosome
3. cell wall
4. cell membrane
The structure most closely
associated with the destruction of
worn out cell organelles is the
1. lysosome
2. centrosome
3. vacuole
4. chromosome

(3.) cell wall
(4.) mitochondrion
Which structure is found ONLY
in animal cells?
(1.) cell wall
(2.) vacuoles
(3.) centrioles

from the oxidation of glucose is stored in
molecules of

(2.) ADP
(3.) ATP
(4.) RNA
3. In the presence of oxygen, _____
molecules of ATP can be formed.
(1.)2
(2.) 19

(4.) 36
6. Muscles cells engaged in vigorous
activity build up relatively high
concentrations of

(3.) alcohol
(4.) oxygen
7. 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

8. Aerobic respiration and
fermentation are similar in that
BOTH processes
