<p>Biosynthetic phase = Does not depend directly on light but relies on ATP, NADPH, CO2, and H2O Dark reaction = A term sometimes considered a misnomer for the biosynthetic phase of photosynthesis Calvin cycle = Describes the complete biosynthetic pathway in photosynthesis Melvin Calvin = Scientist who used radioactive 14C in algal photosynthesis studies</p> Signup and view all the answers

<p>The biosynthetic process continues after light becomes unavailable = Demonstrates that it does not directly depend on light The biosynthetic phase is sometimes called the dark reaction = Discussion as to whether this term is appropriate Melvin Calvin's work involved using radioactive isotopes in photosynthesis studies = Contributed to understanding the first product of CO2 fixation and the Calvin cycle The first CO2 fixation product was a 3-carbon organic acid = Result of Melvin Calvin's research using radioactive 14C</p> Signup and view all the answers

<p>CO2 and H2O = Combined to produce sugars in the biosynthetic phase Radioactive 14C = Used by Melvin Calvin in algal photosynthesis studies 3-carbon organic acid = First product formed during CO2 fixation Light availability = Affects the continuation or stoppage of the biosynthetic process</p> Signup and view all the answers
