- Which of the following substances does not participate in the Calvin-Benson cycle? a. ATP c. NADPH e. PGAL b. O2 d. RuBP f. CO2What is the molecule that leaves the Calvin cycle to be converted into glucose? a. ADP b. G3P c. RuBP d. 3-PGADuring what stage of the Calvin cycle are hexose sugars formed? stage 4 stage 1 stage 5 stage 2 stage 3
- What happens during the carbon fixation stage of the Calvin Cycle (light-indepedent reactions)? Energy from ATP and electrons from NADPH are used to reduce 3-phosphoglycerate to form G3P molecules (which can be used to form other organic molecules such as glucose) Oxygen is produced through this process The remaining G3P molecules that have exited the cycle are used to re-form RuBP through a series of chemical reactions, so that the Calvin cycle can continue. The enzyme Rubisco attaches to RuBP, causing the formation of molecules of 3-phosphoglycerateIn terms of the spatial organization of photosynthesis within the chloroplast, what is the advantage of the light reactions producing NADPH and ATP on the stroma side of the thylakoid membrane?Plant chloroplasts are able to generate which of the following inorganic product molecules during oxygenic photosynthesis? C6H12O6 CO CO2 O2 H2S
- Eukaryotic chloroplasts generate exactly how many product molecules, in their consumption of six substrate carbon dioxide molecules and twelve water molecules, during oxygenic photosynthesis? twelve C6H12O6 molecules, six H2O molecules, and three CO2 molecules are produced one C6H12O6 molecule, six H2O molecules, and six O2 molecules are produced six C6H12O6 molecules, three H2O molecules, and six CO2 molecules are produced twelve H2O molecules and six O2 molecules are produced six H2O molecules and twelve CO2 molecules are producedDraw a diagram of the dark phase of photosynthesis. You must represent this phase in the form of a cycle indicating the parts of carboxylation, reduction, generation of hexoses and regeneration. Ribulose, CO2, rubisco, phosphoglycerate (PGA), bisphosphoglycerate, phosphoglyceraldehyde (PGAL), ATP, ADP, NADPH, NADP, kinase, fructose, and glucose should appear.The light reactions in chloroplasts power the creation of ATP via chemiosmosis. In relation to this process, which of the following is true? 1. ATP synthase breaks ATP down into ADP, creating energy to fuel chemiosmosis.2. Oxygen is used as a source of electrons to replace those lost in photosystem II.3. Chemiosmosis during the light reactions is also used in the reduction of NADPH and FADH2.4. As excited electrons fall back down to a lower energy state, they create a proton gradient that is used to fuel the phosphorylation of ADP.

STROMA (low H+ concentration) Light THYLAKOID SPACE (high H+ concentration) STROMA (low H+ concentration) Photosystem II 4 H+ H₂O 1 1/2 0₂ +2 H+ Thylakoid membrane Cytochrome complex Light Pq 4 H+ Photosystem I Pc ATP synthase ADP + H+ Fd M ATP NADP+ reductase NADP+ + H+ NADPH To Calvin Cycle1) When a leaf on an oak tree absorbs 15,440 photons, how many glyceraldehyde-3-phosphate molecules can be produced by the Calvin cycle? b)When a leaf on an oak tree absorbs 15,440 photons, how many glyceraldehyde-3-phosphate molecules can be produced by the Calvin cycle?Name the major inputs and outputs of the Calvin cycle.
