The three phases of the Calvin cycle are: 1. Carbon fixation. 2. Reduction. 3. Regeneration of the CO2 acceptor. The phase(s)that involve(s) a phosphorylation step using ATP is/are… A. 1 only. B. 2 only. C. 3 only. D. 1 and 2 but not 3. E. 2 and 3 but not 1.
The phase(s)that involve(s) a phosphorylation step using ATP is/are:
E. 2 and 3 but not 1. is correct one among other options.
Explanation is done by help of figure attached. Phase 1 carbon fixation does not involves the phosphorylation of ATP while other both Phase 2 and phase 3 involves the phosphorylation of ATP and shown in the outline diagram of calvin cycle.

The three phases of the Calvin cycle are: 1. Carbon fixation. 2. Reduction. 3. Regeneration of...
Which of the following does not occur during the calvin cycle? a) oxidation of NADPH b) release of oxygen c) regeneration of the CO2 acceptor d) carbon fixation
Photosynthesis - what is meant by each round? Carbon fixation occurs in the stroma of the chloroplast in a process known as the Calvin Cycle. It occurs in three stages: Stage 1: Carbon Fixation, Stage 2: Reduction, and Stage 3: Regeneration of RuBP. In Stage 1, __ molecule(s) of CO2 are added to __ molecules of RuBP, which was regenerated from the previous cycle. This process is catalyzed by the enzyme Rubisco. The final product from each round of the...
QUESTION 5 This question explores the Calvin cycle in plants. A summary of the three stages of CO, assimilation in photosynthetic organisms is shown below (Fig. 20-31 from the text book). All the reactions of the Calvin cycle in detail are shown on the last page. Only the first three reactions are directly involved in carbon-fxation, assimilation and reduction, to Stage 3: ATP3 Regeneration of (3) Stage 1a Ribulose 1.5 e (GAP). The rest of the pathway results in the...
77. Of the following, which occurs during the Calvin cycle? a) Excited electrons are conveyed from chlorophyll to an electron acceptor b) Light energy is converted to chemical energy C) ATP and NADPH are synthesized d) Photons are absorbed e) CO2 is reduced 78. Which of the following occurs during the Calvin cycle? a) Linear electron flow produces the materials required for the fixation of carbon from carbon dioxide. b) Light energy is converted to chemical energy c) ATP is...
The phosphorylation of the 3 carbon molecule generated during the carbon reduction stage of the Calvin Cycle is carried out by
Draw how the chemical structure changes during the fixation phase of the Calvin Cycle (Ribulose-1,5-bisphosphate + CO2 --> 6-Carbon Intermediate --> 3-Phosphoglycerate). Include enzymes used and any byproducts formed. What enzyme mediates this change in Q3? What does it do? Are there any byproducts other than 3-Phosphoglycerate? Why or why not?
The Calvin Benson cycle use the energy trapped in ATP and NADPH generated by the light reactions to build sugars from CO2. What below is FALSE regarding this sugar-building cycle? Select one: a. Initially RuBP is carboxylated by RuBisCo where atmospheric CO2 is captured and put into the cycle. b. ATP and NADPH generated by the light reactions are used to reduce 3PG to a more energetic/reduced G3P (some of which will be diverted off to build sugar!) c. More...
