Photosynthesis Quiz

Which of the following is used by cells to store and release energy needed to power cellular processes?

• ATP
• NADPH
• RNA
• DNA

Energy is released when

• ADP reacts with a phosphate group to form ATP.
• a phosphate group breaks away from ATP.
• a plant produces carbohydrates.
• a battery is recharged.

Chlorophyll is a pigment found in chloroplasts that

• reflects green light
• absorbs green light
• stores energy
• makes up the stroma

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

• the thylakoid membranes.
• pigments such as carotene.
• electron carriers such as NADP+.
• the protein ATP synthase.

The clusters of chlorophyll and proteins that absorb sunlight and generate high-energy electrons in the chloroplasts are called

• carrier proteints
• transport proteins
• photosystems
• synthase proteins

n photosystem II, as high-energy electrons are passed to the electron transport chain, the chlorophyll gains new electrons from

• oxygen atoms
• water molecules
• hydrogen ions
• carbon dioxide

The ability to do work is called

• respiration
• energy
• photosynthesis
• active transport

• ADP
• ATP
• Glucose
• GMP

The structure where photosynthesis takes place is the

• chloroplast
• cytoplasm
• mitochondria
• nucleus

Organisms that make their own food, such as green plants and algae, are called

• organic
• autotrophs
• heterotrophs
• inorganic
