Study Notes

Energy and Its Sources

Energy is the ability to do work, and it ultimately comes from the sun on Earth.

Photosynthesis

Plants use photosynthesis to make sugar and oxygen from carbon dioxide and water.
Photosynthesis is a type of endothermic reaction, meaning it absorbs energy.
The primary source of energy needed to drive photosynthesis is light energy from the sun.

Cellular Respiration

Organisms use sugar as a source of energy for their cellular activities.
Cells synthesize ATP (adenosine triphosphate) using the energy released from the breakdown of sugar.
ATP is the usable form of energy that cells convert sugar into.
Cellular respiration is necessary for life because it provides energy for the cell's various activities.

Relationship between Photosynthesis and Cellular Respiration

Photosynthesis and cellular respiration are related in that they are complementary processes.
Photosynthesis produces the sugar and oxygen that are then used by cellular respiration to produce energy.
