How do heterotrophs and autotrophs differ in the way they obtain energy?

• Heterotrophs produce their own energy while Autotrophs need to eat other organisms

• Autotrophs produce their own energy andHeterotrophs eat only Autorophs

Compare the amounts of energy stored by ATP and glucose.

• ATP has more energy than glucose

• Glucose has more energy than ATP

• ATP and glucose have similar amounts of energy

• Neither ATP or glucose store energy

Describe how ATP can release and store energy for the cell.

• ATP cannot release energy, only store energy

• ATP gets charged by the sun and energy is used by the organism

• ATP makes and breaks the chemical bond of the 3rd phosphate group to release energy

• I forgot my charger so my ATP is dead today

How do plants synthesize high-energy carbohydrates?

• By combining low-energy carbohydrates

• Store sunlight

• Reflect sunlight

• Change light to heat

High-energy electrons are transported from chlorophyll to other molecules in the chloroplast by...

• The thylakoid

• Pigment such as carotene

• Electron carriers such as NADP+

• The protein of ATP synthase

What are the two main parts of a chloroplast where photosynthesis occurs.

• Thylakoid and stroma
