Revision notes on 5.1.2 The Light Dependent Reaction for the AQA A Level Biology syllabus, written by the Biology experts at Save My Exams.
The light-independent reactions are collectively known as the Calvin cycle and uses ATP and reduced NADP from the light-dependent stage to produce glucose. Carbon fixation occurs. 5-carbon ribulose bisphosphate (5C RuBP) combines with carbon dioxide.

- You are correct. When we split the H2O, our 2 protons in the hydrogen (the h+ ions, basically just a proton floating around), the waste product of...
- ATP consists of adenosine - itself composed of an adenine ring and a ribose sugar - and three phosphate groups (triphosphate). The phosphoryl group...
- at first hydrogen ions are pushed into lumen, but as the concentration increases inside the lumen , it is going to activate the ATP synthase enzyme...
- Remember that all aqueous solutions contain a small amount of hydronium (H₃O⁺) and hydroxide (OH¯) due to autoionization§. This means that processe...
- Quite interesting question! I do not think it would be possible. Plant cells are not designed to accept/tolerate infrared or UV light (which is des...
- Electrons move down the transport chain, which creates a proton gradient, and then that gradient is used to make ATP
- Some must get used within the chloroplast for other metabolic processes, but my understanding is that most gets used to fix carbon — this uses a lo...
- ？？i am so screwed for AP bio
- I don't understand what you mean. Do you mean in ball-and-stick models, or overall? I don't think oxygen has an overall color...
Using the energy carriers formed in the first steps of photosynthesis, the light-independent reactions, or the Calvin cycle, take in CO 2 from the environment. An enzyme, RuBisCO, catalyzes a reaction with CO 2 and another molecule, RuBP.
Jan 18, 2022 · Light-dependent reaction is the series of biochemical reactions in photosynthesis requiring light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy (ATP and NADPH).
The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH.

Jan 27, 2022 · Light-independent reaction is a series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide. The energy released from ATP (produced during the light reactions ) drives this metabolic pathway.
