Heterotrophs are organisms that can

• Produce food from sunlight and some inorganic molecules

• Survive without energy

• Consume other organisms for energy

• Carry out either photosynthesis or chemosynthesis

The process whereby plants capture energy and make complex molecules is known as

• homeostasis

• photosynthesis

• carbon dioxide

• water

NADP+ is important in photosynthesis because it

• Is needed to form chlorophyll

• Provides additional oxygen atoms

• Is responsible for carrying H’s to the stroma

• Provides protons for some reactions

The source of oxygen produced during photosynthesis is

• Carbon dioxide

• chlorophyll

• Water

• glucose

The major atmospheric byproduct (waste product) of photosynthesis is

• Nitrogen

• water

• Carbon dioxide

• oxygen

During the Calvin Cycle, carbon containing molecules are produced from

• Carbon atoms from ATP

• Carbon atoms from carbon dioxide in the air and hydrogen atoms from water

• Carbon atoms from carbon dioxide in the air and hydrogen atoms from NADPH

• Carbon atoms, hydrogen atoms, and oxygen atoms from glucose

Products of the light reactions of photosynthesis that provide energy for the Calvin Cycle are

• Oxygen and ATP

• ATP and NADPH

• Water and oxygen

• Oxygen and NADPH

The Calvin Cycle of photosynthesis

• Requires ATP and NADPH

• Can occur in both light and dark conditions

• Produces glucose

• All of the above

The energy used in the Calvin Cycle for the production of carbohydrate molecules comes from

• ATP made during cellular respiration

• The Krebs cycle

• ATP made in the light reaction of photosynthesis

• CO2 absorbed during the last stage of photosynthesis
