PEP in the mesophyll cells is converted to oxaloacetic acid (OAA), which is then further converted into a 4-carbon compound such as malic acid or aspartic acid, which is then transported to the bundle sheath cells. molecule of CO. Regeneration: This stage involves the NCERT Exemplar Class 11 Biology Chapter 13 Photosynthesis in Higher Plants are part of NCERT Exemplar Class 11 Biology. 30 seconds . It requires one molecule of ATP for Question 11 . Hatch and Roger Slack and thus named as Hatch and Slack pathway.

The primary CO2 acceptor is Ribulose bi phosphate (RUBP a 5 Carbon compound). The reactions of the Calvin cycle are not directly dependent on light, but they usually do not occur at night. Explain. The Hatch and Slack pathway is a cyclic pathway for CO 2 fixation.. About 85% of the plants in the world are C3 plants where the atmospheric Carbon dioxide is fixed by RUBISCO to produce a 3-carbon compound in the first step of the Calvin cycle and gives rise to the energy-wasting process known as photorespiration. Briefly explain the pathways 2 and 3. It uses ATP and NADPH, produced during the light reactions, to synthesise OR Describe in detail with a diagram the structure of DNA with functions. C3 Plants. MCQ Questions for Class 11 Biology: Ch 14 Respiration in Plants. The Calvin cycle has three main stages: Carboxylation: It is the first phase of the Calvin cycle.

The Calvin cycle occurs in the stroma of the chloroplast. It uses ATP and NADPH, produced during the light reactions, to synthesise Here we have provided NCERT Exemplar Problems Solutions along with NCERT Exemplar Problems Class 11.. The Calvin cycle is a set of light independent redox reactions that occur during photosynthesis and carbon fixation to convert carbon dioxide into the sugar glucose. The assimilatory power needed for Calvin cycle is provided by the events of light deacidification. You may need to download version 2.0 now from the Chrome Web Store. 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.
