the early suggestion that oxygen (O2) liberated from plants during photosynthesis comes from water was

• first proposed by C B Van Neil of Stanford University

• confirmed by experiments using ¹⁸O

• made following the discovery of photorespiration because of rubiscos sensitivity to oxygen

• A and B

• A B and C

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

• RuBP

• O2

• G3P

• PGA

• Glucose

• these reactions begin soon after sundown and end before sunrise

• rubisco attaches carbon dioxide to ribulose biphosphate

• one of the end products is glyceraldehyde phosphate
