Interpretation: The reason the Calvin cycle is crucial to the functioning of all life forms should be determined.
Concept introduction:
The Calvin cycle is a process used by the plants and algae to convert inorganic carbon dioxide from the atmosphere into carbohydrates, which is important for the growth and functioning of plants.
Explanation of Solution
All living forms on earth depend on photosynthesis directly or indirectly. Autotrophs and plants depend on their energy and food requirements on the Calvin cycle. Heterotrophs depend on plants for food and thus indirectly rely on the Calvin cycle.
The Calvin cycle is divided into four main stages: carbon fixation, reduction phase, carbohydrate formation and regeneration. In order to fuel the reactions of the Calvin cycle, energy is obtained from ATP and NADPH. These chemical compounds transfer the energy captured from sunlight. Therefore, all life forms directly or indirectly depend on the Calvin cycle for their survival.
The Calvin cycle is crucial to the functioning of all life forms as autotrophs and heterotrophs directly or indirectly rely on the Calvin cycle for food and energy.

- 49. Which of these is NOT true of the citric acid cycle? Group of answer choices The citric acid cycle uses both NAD+ and FADH as electron carriers. The citric acid cycle produces ATP via oxidative phosphorylation. The citric acid cycle produces two ATP per glucose molecule. The citric acid cycle occurs in the mitochondria.arrow_forwardModified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true. Triose phosphate is considered as the net product of the Calvin cycle of photosynthesis, which is then utilized for the synthesis of the end products that are glucose and starch.arrow_forwardTrue or False: 1. Electron-deficient chlorophyll molecules of PS II receives electron from PS I. 2. Xanthophylls around the reaction centers transfer their energy to chlorophyll molecules. 3. CO2 is fixated when it combines with the phosphate during the initial phase of the Calvin cycle.arrow_forward
- true or false 1. Phosphoenolpyruvate carboxykinase is the enzyme involved in the carbon dioxide fixation in the mesophyll cells of C4 plants 2. The C4 pathway utilizes less ATP than C3 pathway thus enabling C4 plants to adapt to tropical temperatures. 3. Photorespiration occurs when [O2]/[CO2] is high. 4. The carboxylase activity of RuBisCO catalyzes the fixation of carbon dioxide. 5. In cyclic photophosphorylation, only ATP is produced. 6. Chlorophyll has iron as the metal center of the porphyrin ring.arrow_forwardSmall explanation please. what is a product in the first stage of the Q- cycle? a. two electrons b.

- 02 is neither involved in glycolysis nor citric acid cycle but is still, one cycle is called aerobe and the other anaerobe. Explain which pathway is aerobe and which is anaerobe and why.arrow_forwardTCA cycle, the mere fact that it’s a cycle means that you always end the cycle where you began. Why then run the cycle? What are its real products?arrow_forwardStatement 1: In the Calvin Cycle, two molecules of glyceraldehyde 3-phosphate are produced if two molecules of carbon dioxide are fixed. Statement 2: If the carbon fixation phase of the Calvin Cycle begins with 6 molecules of ribulose bisphosphate and 6 molecules of carbon dioxide, 2 out of 12 molecules of glyceraldehyde 3-phosphate made at the end of the reduction phase are used in carbohydrate production while the remaining 10 molecules are needed to keep the Calvin Cycle turning by regenerating ribulose bisphosphate.
