Carbon atoms end up in you, and in other life forms, thanks to the second stage of photosynthesis, known as the Calvin cycle (or the light-independent reactions).
What are the 2 steps phases of photosynthesis?
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
Where does step 2 of photosynthesis occur?
The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
What are the two stages of photosynthesis quizlet?
What are the two stages of photosynthesis? 1=light reactions/light dependent reactions. 2=the calvin cycle/light independent reactions.
What are the two types of photosynthesis?
There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis.
15 related questions foundWhich is the first step in photosynthesis?
The first step in photosynthesis is the light reaction or photochemical reactions resulting in the formation of ATP and NADPH, which are later utilised in the biosynthesis process. In the first stage, light energy is captured and converted to chemical energy.
What is the first step of photosynthesis quizlet?
The first stage of photosynthesis is called the light reactions. During this stage, light is absorbed and transformed to chemical energy in the bonds of NADPH and ATP.

What 2 products of light reactions are used in the Calvin cycle?
This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
Which of the following is the second step of the Calvin cycle?
Reduction. In the second stage of the Calvin cycle, the 3-PGA molecules created through carbon fixation are converted into molecules of a simple sugar – glyceraldehyde-3 phosphate (G3P). This stage uses energy from ATP and NADPH created in the light-dependent reactions of photosynthesis.
What are the 3 steps of photosynthesis?
The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.
What are the 3 steps in the Calvin cycle?
These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them. There are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration.
What are the 3 stages of Calvin cycle?
The Calvin cycle reactions ([Figure 2]) can be organized into three basic stages: fixation, reduction, and regeneration. In the stroma, in addition to CO2, two other chemicals are present to initiate the Calvin cycle: an enzyme abbreviated RuBisCO, and the molecule ribulose bisphosphate (RuBP).
Which of the following is the second step of the Calvin cycle quizlet?
Reduction is the second step of the Calvin cycle where NADPH is needed. NADPH is a reducing agent that is used in the Calvin cycle that transfers electrons that allow carbohydrates to be synthesized from carbon dioxide.
