Webb• Most plants are C 3 plants, in which the initial fixation of CO 2, via rubisco, forms a three-carbon compound (3-phosphoglycerate) • In photorespiration, rubisco binds with O 2 instead of CO 2, producing a two-carbon compound 66 • Photorespiration is costly because it consumes O 2 and organic fuel without producing any ATP or sugar • It is thought to … WebbThe pyruvate generated as an end-product of glycolysis is a substrate for the Krebs Cycle. Glycolysis is viewed as consisting of two phases with five steps each. In phase 1, "the preparatory phase", glucose is converted to 2 d-glyceraldehyde-3-phosphate (g3p). One ATP is invested in Step 1, and another ATP is invested in Step 3.
