All living cells burn sugar and use the energy to recharge ADP to ATP
During cell respiration sugar is made
During cell respiration sugar is broken down into water and CO2
During Cell respiration oxygen is released to the air
During cell respiration Carbon dioxide is released from the organism to its environment
During cell respiration sugar turns into ATP
During cell respiration the energy released from sugar is used to recharge ADP to ATP
During cellular respiration energy from the sun is stored inside the bonds of glucose
sugar
During Cell respiration Energy in the bonds of glucose sugar is released and used to
recharge ADP to ATP. Cells then use ATP for energy
Only animal cells do cell respiration
Only plant cells do cell respiration
All cells use ATP for energy.
All cells break down food molecules to release energy… then use that energy to
recharge ADP to ATP. Cells then use the ATP molecule to get energy when needed.
The process of cell respiration is exactly opposite of photosynthesis.
The process of cell respiration is exactly the same as photosynthesis
C6 H12 O6 is cell respiration

is the chemical equation which represents Cell respiration
r.
6H20

6 CO2
+ Energy ------ C6 H12 O6 + 6O2
Is the chemical equation which represents cell respiration
s.
When sugar is broken down in living cells… It is broken down into water and carbon dioxide.
t.
The reason that you breathe – out more CO2 than you breathe in is that all of your cells are breaking
down sugar… and Carbon dioxide is produced when sugar is broken down.
2.
Write the chemical equation for Cell Respiration
3.
A snail is placed in a test tube with some dead algae. The algae is not able to make sugar. The test tube
is sealed air-tight with a cork. There is enough oxygen in the test tube for the snail to survive for many
months. The snail feeds on the dead algae getting sugars from the dead cells.
The snails cells then break down the sugar during cell respiration. Based on this information… which is
most likely to happen?
A. The level of CO2 in the test tube will increase as sugar is broken down. in the snail cells
B. The level of CO2 in the test tube will decrease as sugar is broken down in the snail cells
C. The level of CO2 in the test tube will stay the same as sugar is broken down in the snail cells.
4.
Which of the following living things rely on cell respiration in order to recharge ADP to ATP ?
A.
A white pine tree
D. A Blue whale
E. Grass plants
G. Bacteria
5.
In order to break down sugar efficiently… living cells use a gas from the air called __________________
6.
If oxygen is used to break down sugar during cell respiration… each molecule of sugar which is
burned will provide enough energy to recharge ________ molecules of ADP to ATP
B. A raccoon
D. . Humans
F. Bread mold
H. Corn plants
7. If sugar is burned without oxygen. The cell can only recharge _________ molecules of ATP for
every molecule of sugar burned
8. Why do you breathe? Use the ideas of cell respiration and ATP in your answer.
