Aerobic and Anaerobic Cellular
Respiration
Aerobic respiration is cellular respiration that
requires oxygen.
•
Anaerobic respiration is cellular respiration that
doesn’t require oxygen. (For example:
Glycolysis)
•
Glycolysis is the breakdown of glucose by
enzymes, releasing energy and pyruvic acid.
•
Products of Photosynthesis used
for Cellular Respiration
Water, light, and carbon dioxide are needed to photosynthesize,
the result would be oxygen (O2) and glucose (C6H12O6).
•
With Oxygen and Glucose available, cellular respiration can
occur.
•
Cellular Respiration is the process that releases energy from
food in presence of oxygen.
•
When sugar and oxygen are consumed the products are Carbon
Dioxide, Water, and Energy.
•
Products of Cellular Respiration used
for Photosynthesis
Oxygen, and glucose are needed for a plant to undergo Cellular
Respiration, the results are energy, carbon dioxide, and water.
•
With those three components available, Photosynthesis can
occur. (Light is also needed.)
•
Photosynthesis is the plants way of making its own food.
•
When photosynthesis happens it needs energy to start and so is
sunlight. It absorbs the carbon dioxide and water through the
leaves.
•
ATP’s role to energy transfers
within a cell
ATP stands for Adenosine Triphosphate.
•
The role of the ATP is to transport chemical
energy within cells for metabolism.
•
Comparison of Cellular Respiration
and Photosynthesis
Photosynthesis takes carbon dioxide out of the
atmosphere and replaces it with oxygen.
•
Cellular Respiration puts carbon dioxide back
into the atmosphere, using the oxygen they
produced to eat food.
•
Storing and releasing of organic
compounds
In photosynthesis, when the process is
complete glucose (C H O ) is made and
stored for food. (Occurs in chloroplast)

In cellular respiration, glucose that is
produced is used as food. This later produces
ATP and is released as heat.
