•A Chemical reaction that produces food.

organisms that contain chlorophyll can carry out photosynthesis

Photosynthesis takes place in the

Chlorophyll traps the sun’s energy so it can be used.

Provides the energy for photosynthesis

This means: 6 molecules of water plus 6 molecules of carbon dioxide in the presence of sunlight and chlorophyll produces 1 molecule of glucose and 6 molecules of oxygen

Has to be present in order for cellular respiration to occur.

The mitochondria in the cell changes the energy stored in glucose into a form of energy that can be used by the cell to carry out life processes.

Is the form of energy produced in the mitochondria

ATP is produced during

which takes place primarily in the

If oxygen is present, 1 molecule of glucose will produce 36 molecules of ATP

Also known as aerobic respiration

This will only occur if oxygen is present
