What is the process in which ATP is produced called?

• Glycolysis

• Chemiosmosis

• Fermentation

• Photosynthesis

What diffuses from a region of high concentration to a region of low concentration during chemiosmosis?

• Electrons

• Neutrons

• Protons

• Oxygen

Through what type of membrane do protons diffuse during chemiosmosis?

• Fully permeable membrane

• Impermeable membrane

• Partially permeable membrane

• Non-permeable membrane

What is formed when an inorganic phosphate is attached to ADP during chemiosmosis?

• ATP

• NADH

• FADH2

• Glucose

What does the process of chemiosmosis rely on?

• Production of a proton concentration gradient

• Production of a neutron concentration gradient

• Production of an electron concentration gradient

• Production of an oxygen concentration gradient

In which two ways are electrons raised to higher energy levels?

• Absorbing light and using the energy released when bonds break

• Absorbing sound and using the energy released when bonds form

• Absorbing heat and using the energy released when bonds break

• Absorbing light and using the energy released when bonds form

What happens to excited electrons after they are raised to higher energy levels?

• They pass onto an electron transport chain where a proton gradient is produced

• They release energy in the form of light

• They combine with protons to form hydrogen atoms

• They return to their original energy levels

• Thylakoids of chloroplasts

• Cytoplasm

• Nucleus

Which of the following is NOT a part of the light-dependent stage of photosynthesis?

• Light harvesting at the photosystems

• Photophosphorylation

• Formation of reduced NADP

• Calvin cycle

What is produced during photophosphorylation in the light-dependent stage of photosynthesis?

• NADPH

• ATP

• Glucose

• Oxygen
