Question
Chapter 8, Problem 2CQ
Summary Introduction
To determine: The function of NADPH during the Calvin cycle.
Introduction: The researcher Melvin Calvin, Andrew Adam Benson along with their colleagues discovered the Calvin cycle. This is an energy driven cycle that requires six carbon dioxide molecules to synthesise one molecule of glucose using 18 ATP molecules and 12 NADPH molecules.

Question options: Krebs cycle glycolysis this process does NOT occur during any of the listed stages electron transport pathway Calvin cyclearrow_forwardAnswers can be kept very simple and concise Photosynthesis: A) Is NADPH consumed during the light reactions or Calvin cycle? What is it’s energy used to do? Protons move across the thylakoid membrane in both directions during the light reactions of photosynthesis. B) When protons move in to the thylakoid, are they moving up or down their concentration gradient? (From low to high concentration or from high to low concentration?) C) Since protons are charged, they cannot freely diffuse across a plasma membrane. What protein(s) facilitate the transport of protons in to the thylakoid?arrow_forward
- A decrease in entropy occurs during the CO2 uptake phase of the Calvin cycle, as freely moving CO2 molecules become fixed into a carbon skeleton. How can this occur without direct participation by NADPH and/or ATP?arrow_forwardPlease compare and contrast the light dependent reactions of photosynthesis and the electron transport chain in cellular respiration. You must describe all components of each pathway, including their purpose and location. In addition, you must discuss the electrons, their energy levels at each stage, what the extracted energy is used for, and what the final electron carrier/receptor is for each pathwayarrow_forwardWhat are the stages of the Calvin-Benson cycle? Select all that apply. The resulting unstable six-carbon molecule splits into two three-carbon molecules of PGA. ATP and NADPH are used to convert PGA molecules to PGAL. Most of the PGAL is used to regenerate RuBP, but some is exported to the cytoplasm to produce carbohydrates. Rubisco attaches CO2 to a five-carbon organic compound called RuBP. Rubisco is used to convert PGA molecules to PGAL.arrow_forward
