Cell Energy
| Definition | Term |
|---|---|
| responsible for the energy within food | chemical bonds |
| photosynthesis | process in which the energy of sunlight is used to produce food |
| first step in photosynthesis | energy in the form of sunligh is captured by the chlorphyll in the chloroplasts |
| second step in photosynthesis | radiant energy of sunlight is converted into the chemical energy found in food |
| glucose | simple sugar produced by photosynthesis |
| requirements for photosynthesis | water, carbon dioxide, and radiant energy |
| oxygen | waste product of photosynthesis |
| autotrophs | organisms that can make their on food |
| heterotrophs | organisms that cannot make their on food |
| respiration | process in which simple food substances such as glucose are broken down and the energy they contain is released |
| aerobic respiration | chemical reactions occuring in the mitochondria in which simple substances are brokendown releasing energy. |
| adenosine triphosphate | high energy molecule produced within the mitochondrion of the cell using the energy from food material |
| carbon dioxide and water | waste products produced during respiration |
| anaerobic respiration | process in which food is broken down and energy released without need of oxygen |
| chlorphyl | green pigment found in plant cells |
| sun | primary source of energy for photosynthesis |
| dark phase | chemical reactions within chloroplast occur without the presence of light |
| light phase | chemical reactions within chloroplast occur without the presence of light |
| energy | the ability to do work |
| food material | needed for the material necessary for growth and repair |
| food material | used as an energy source within cells |
| "photo" | means light |
| "synthesis" | means "putting together" |
