WebFixation of one molecule of CO 2 requires 3 ATP and 2 NADPH 2 molecules. 8. Optimum temperature for the operation of C 3 cycle is 10-25°C. 9. There is a net gain of one hexose sugar of 6 CO 2 molecules fixed and reduced. Difference # Hatch-Slack Cycle (C4 Cycle): 1. Hatch-Slack Cycle operates in C 4 plants only. 2. WebJul 11, 2024 · The NADPH produced in the light-dependent stage of photosynthesis provides the chemical energy to fuel the Calvin cycle and keep it going. NADPH vs. ATP Adenosine …
5.3 The Calvin Cycle - Concepts of Biology OpenStax
WebSix turns of the calvin cycle results in the formation of one molecule of glucose. For one turn: ATP used = 3 molecules NADPH used = 2 molecules Thus for six cycles : ATP used = 3*6 = 18 molecules NADPH used = 2*6 = 12 molecules Therefore total ATP and NADPH required to produce one molecule of glucose is 18 and 12 respectively. Suggest Corrections WebSep 28, 2024 · In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue. In summary, it takes six turns of the Calvin cycle to fix six carbon … the pier man
Calvin Cycle and Hatch-Slack Cycle Photosynthesis - Biology …
WebH+ is used to power the formation of ATP molecules (energy currency) iv. Electrons from water are also used to form NADPH molecules v. CO2 is attached to 5-carbon acceptor sugar by the enzyme Rubisco vi. This new 6-carbon sugar splits into 2 3-carbon sugars vii. Multiple 3-carbon sugars + ATP + NADPH yield glucose and the precursor 5-carbon ... WebIt consists of three major steps: 1. Carboxylation: Zero ATP and zero NADPH. 2. Reversal of glycolysis: Two ATP and two NADPH. 3. Regeneration of RuBP: One ATP and zero NADPH. Hence for every CO$$_2$$ molecule entering the calvin cycle, 3 molecules of ATP and 2 of NADPH are required. So, the correct answer is '3ATP + 2 NADPH 2'. WebThe Calvin cycle has three stages. 1)carbon fixation 2)reduction 3)regeneration. At the end of each Calvin cycle net gain is 9ATP and 6 NADPH2.In each Calvin cycle, 3 CO2 molecules are fixed with RuBP to form 2 molecules of 3PGA in the first step. Later two molecules of 3PGA through a series of reactions regenerate 2RuBP in the third stage. sick transit
