What is the primary function of thylakoids in chloroplasts during photosynthesis?

• To store glucose
• To maintain charge separation across membranes
• To produce carbon dioxide
• To break down ATP

What is the primary function of ATP synthase in the thylakoid membrane?

• To split water molecules
• To rotate and produce ATP from ADP and phosphate
• To transport electrons through the membrane
• To produce NADPH directly

Thylakoids contain clusters of chlorophyll and proteins known as________________________________. They absorb sunlight and generate high-energy ( electrons / protons / oxygen atoms / sodium ions ) that pass along the ( photosystem chain / oxygen receptor / electron transport chain / outer membrane ) .

• chloroplasts
• stroma
• photosynthesis
• photosystems

The thylakoid membrane contains a protein called ATP synthase. As hydrogen ions pass through the protein, ADP and a phosphate group are combined to form ATP. What is the direct energy source, if any, for the movement of hydrogen ions and the formation of ATP?

• The energy source is the high-energy electrons that accompany the hydrogen ions.
• The energy source is the concentration difference of hydrogen ions across the membrane.
• The energy source is a set of ATP molecules that gather inside the thylakoid.
• There is no energy source; the process occurs without an energy input.
