A scientist is using a species of green algae to study electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae, but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibits PS I but does not affect PS II (case 2). Which of the following results is expected? In case 1, only PS I completely loses function; in case 2, no proton gradient is produced. In case 1, only PS I completely loses function; in case 2, a proton gradient is still produced. In case 1, both PS I and PS II completely lose function; in case 2, no proton gradient is produced. In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
