Transcript of Photosynthesis and Cellular Respiration

Photosynthesis
The process in which the cells of plants and some other organisms use the energy of sunlight to make food
Cellular Respiration
A process where cells break down sugars to release stored energy *THIS CANNOT HAPPEN WITHOUT OXYGEN
What you should now know
Process
Both processes are for energy creation. Both use glucose for main process.
Cellular Respiration is used by animals
Photosynthesis is used by mostly plants
Sunlight is important to all living organisms
Carbon Dioxide, Sunlight, and water are converted into glucose and oxygen in photosynthesis
Molecules are broken down in cellular respiration
Nutrients are converted to energy for cell growth and repair
Cellular respiration is used by animals
Photosynthesis is used by mostly plants
So what are the differences and similarities between cellular respiration and photosynthesis?
Photosynthesis and Cellular Respiration
Processes of Energy Creation
Sunlight provides the energy to make glucose and oxygen from carbon dioxide and water.
Stage 1: Chlorophyll traps the energy of sunlight
Stage 2: Chloroplast uses the energy to change carbon dioxide and water into glucose.
The chlorophyll is found in these Thylakoids
Chloroplast
See those bubbles? That's the oxidation process!!
Food is oxidized and combined with sugars from the food
The product is energy, carbon dioxide, waste and water
Food for Thought
Photosynthesis
Cellular Respiration
Draw this Venn Diagram in your notes and compare and contrast the two processes of energy creation
Not all nutrients consumed is for energy. Some is used for growth and repair.
The Role of ATP and ADP
ADP and ATP are both chemicals used for energy production.

ATP- ATP stands for Adenosine Tri-Phosphate, and is the energy used by an organism in its daily operations. After a simple reaction breaking down ATP to ADP, the energy released from the breaking of a molecular bond is the energy we use to keep ourselves alive.

ADP- stands for Adenosine Diphosphate, and is constantly converting back and forth from ADP to ATP. So, it is the by-product of the breakdown of ATP and recycled to make ATP again.
