In mitochondria, chemiosmosis translocates protons from the matrix into the intermembrane space, whereas in chloroplasts, chemiosmosis translocates protons from

• the stroma to the thylakoid space.
• the thylakoid space to the stroma.
• the matrix to the stroma.
• the stroma to the photosystem II.

The splitting of carbon dioxide to form oxygen gas and carbon compounds occurs during

• photorespiration
• photosynthesis.
• respiration.
• neither photosynthesis nor respiration.

In metabolic processes of cell respiration and photosynthesis, prosthetic groups such as heme and iron–sulfur complexes are encountered in components of the electron transport chain. What do they do?

• act as reducing agents
• both oxidize and reduce during electron transport
• transport protons within the mitochondria and chloroplasts
• donate electrons

When oxygen is released as a result of photosynthesis, it is a direct by–product of

• chemiosmosis.
• splitting water molecules.
• the electron transfer system of photosystem II.
• the electron transfer system of photosystem I.

If photosynthesizing green algae are provided with CO2 synthesized with heavy oxygen (18O), later analysis will show that all but one of the following compounds produced by the algae contain the 18O label. That one is

• O_2.
• 3–phosphoglycerate.
• glucose
• glyceraldehyde 3–phosphate (G3P).
