Q. Problem: The Calvin Cycle: a. is a cyclic pathway that produces three carbon molecules from CO 2.b. 8 years ago. Phase 1 in Calvin cycle: Carbon fixation. The light reactions of photosynthesis supply the Calvin Cycle with _. It breaks down glucose in the presence of oxygen. Plants depend on the Calvin cycle for energy and food.Other organisms, including herbivores, also depend on it indirectly because they depend on plants for food. Problem: The Calvin Cycle: a. is a cyclic pathway that produces three carbon molecules from CO 2.b. Which substance from the light-dependent reactions of photosynthesis is a source of energy for the light-independent reactions? CO2 fixation is the attachment of CO2 to an organic compound called RuBP. The cycle is light-independent because it takes place after the energy has been captured from sunlight.. Practice: The Calvin cycle. The Calvin Cycle can happen at night. It is the most abundant enzyme in the world. Tags: Question 9 . End Product of the Calvin Cycle and is an important intermediate, from which the main macro-molecules can be formed: amino acids, nucleic acids, lipids, and carbohydrates. These reactions occur in the stroma of the chloroplast, which is the fluid-filled region between the thylakoid membrane and inner membrane of the organelle. MEMORY METER. These reactions actually have several names associated … Start studying calvin cycle. Calvin Cycle Definition. Key Concepts: Terms in this set (11) What happens in the Calvin Cycle? In the most general sense, the primary function of the Calvin cycle is to make organic products that plants need using the products from the light reactions of photosynthesis (ATP and NADPH). Google Classroom Facebook Twitter. All these molecules end up in our foods that we digest and use in glycolysis. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place. Tags: Question 7 .

The Calvin cycle, Calvin–Benson–Bassham (CBB) cycle, reductive pentose phosphate cycle (RPP cycle) or C3 cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms.. The fixed carbon is then reduced to carbohydrate. Photorespiration: C3, C4, and CAM plants. Edit. To ensure the best experience, please update your browser. The Calvin cycle. These reactions occur in the stroma of the chloroplast, which is the fluid-filled region between the thylakoid membrane and inner membrane of the organelle. Calvin cycle. The Calvin cycle reactions (Figure 5.15) can be organized into three basic stages: fixation, reduction, and regeneration. In plants, carbon dioxide (CO 2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells.Once in the mesophyll cells, CO 2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.
