Photosynthesis is....

• Endothermic
• Exothermic

What is chemiosmosis?

• Movement of water against a concentration gradient using energy releasaed chemically.
• Movement of electrons along the electron transport chain.
• Movement (diffusion) of protons across ATP synthase down the electrochemical gradient to generate ATP.
• Movement of water into the chloroplast.

The process of transforming ADP to ATP in photosynthesis is known as?

• Reduction
• Regeneration
• Chemiosmosis
• Photophosphorylation

During photosynthesis, what is pumped across the membrane and into the thylakoid space of the chloroplast?

• Electrons
• Hydrogen ions
• Water
• Carbon dioxide

What is grana?

• Stacks of thylakoids that contain photosynthetic pigments.
• The fluid enclosed in the chloroplast.
• The fluid enclosed in the mitochondria.
• Folds on the innner membrane of the mitochondria.

What is the stroma?

• Stacks of thylakoids that contain photosynthetic pigments.
• The fluid enclosed in the chloroplast.
• The fluid enclosed in the mitochondria.
• Folds on the innner membrane of the mitochondria.

In which part of the chloroplast does the light-dependent reaction take place?

• Matrix
• Cristae
• Thylakoid membrane
• Stroma

In which part of the chloroplast does the light-independent reaction take place

• Matrix
• Cristae
• Thylakoid membrane
• Stroma

Where does photolysis take place?

• Photosystem I
• Photosystem II
