• ATP

• ADP

• NADPH

• NADP

Which is not a characteristic of energy?

• Cannot be created not destroyed

• Is the capacity to do work

• Exists in forms such as chemical, light, and mechanical

• Changes spontaneously from disorder to order

What describes an important link between photosynthesis and cellular respiration?

• Photosynthesis produces CO2 needed for cellular respiration

• Cellular respiration provides ATP so that photosynthesis can happen

• Photosynthesis makes oxygen and glucose needed for cellular respiration

• Photosynthesis and cellular respiration are independent of each other
