Energy V - Photosynthesis (Calvin Cycle) The light reactions of photosynthesis produce ATP, which provides the Calvin cycle with the necessary energy. In addition, the NADPH produced by the light reactions provides the reducing power to put glucose together.

- Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls. Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma.

- Light and dark reactions in photosynthesis Photosynthesis is divided into two parts: 1. Light-dependent reactions (light reactions) 2. Light-independent reactions (dark reactions). Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls.

Photosynthesis uses energy from sunlight to synthesise organic molecules from inorganic sources The light dependent reaction takes place in the chloroplast and is important to produce ATP and NADPH + H+. Both molecules and carbon dioxide (CO2) are needed in the light independent reaction (Calvin Cycle) to produce a hexose sugar, such as glucose, from RuBP. Glucose is used to in the mitochondrion to produce the energy molecule ATP. NAD+ is also needed for respiration, but is not produced by photosynthesis.

Plant Metabolism - Plant Biology During the dark reactions, energy rich ATP and NADPH molecules produced earlier are used to help convert carbon dioxide (CO2) into organic molecules needed by the plant, such as glucose. This involves a very complex series of reactions known as the Calvin Cycle. Lets take a closer look.

Calvin cycle The Calvin cycle is the set of chemical reactions that take place in chloroplasts during photosynthesis. The cycle is light-independent because it takes place after the energy has been captured from sunlight. The Calvin cycle is named after Melvin C. Calvin, who won a Nobel Prize in Chemistry for finding it in 1961. Calvin and his colleagues did the work at the University of California, Berkeley.

Light-independent reaction The process, known as the Calvin cycle, uses products of the light-dependent reactions (ATP and NADPH) and various enzymes. Therefore, the light-independent reaction cannot happen without the light-dependent reaction. Sugars made in the light-independent reactions are then moved around the plant by translocation.

How does the Calvin cycle make sugar? Answered by The Community. Making the world better, one answer at a time. Using Carbon from CO2, energy from ATP, and high-energy electrons from NADPH, the Calvin Cycle constructs an energy-rich sugar molecule called glyceraldehyde 3 phosphate (G3P). The plant cell can then use G3P as the raw material to make the glucose and other organic compounds that it needs.

Chapter 10 - Photosynthesis 1). To reduce six molecules of carbon dioxide to glucose via photosynthesis, how many molecules of NADPH and ATP are required? Answer: For every three molecules of CO2 that enters the Calvin cycle, one molecule of the three carbon glyceraldehyde 3-phosphate (G3P) is produced. Two molecules of G3P are needed to produce one molecule of glucose. Therefore, the Calvin cycle needs to make a total of 6 turns to produce two molecules of G3P. One turn of the Calvin cycle requires 3 molecules of ATP and 2 molecules of NADPH so for 6 turns:

Making sugar from carbon dioxide: The Calvin Cycle Making sugar from carbon dioxide: The Calvin Cycle. The process of photosynthesis is often described as turning sunlight into sugars, and while that's broadly true, there are two distinct biochemical reactions taking place. The first uses the sunlight to create energy inside the cell and the second takes carbon dioxide and uses it to make sugars. The second is the Calvin cycle although the name is a little unfashionable nowadays.

Calvin cycle At this stage of photosynthesis, the energy released from ATP produced during light reactions is used to drive the conversion of carbon dioxide and other compounds into an organic molecule (e.g. glucose). In C3 plants, the Calvin cycle is used directly to fix carbon dioxide. In C4 plants and CAM plants, a different carbon fixation precedes Calvin cycle. Word origin: named after one of the discoverers, Melvin Calvin, a Nobel prize-winning chemist. See also: Photosynthesis on Tutorials for further information.

Biosynthesis The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers ( ATP and NADPH) are products of light-dependent reactions.

BIOLOGY question? CO2 enters the Calvin cycle and as the reaction occurs ATP and NADPH from the light reactions are used to drive the steps leading to the formation of C6H12O6. Additional ATP is used to complete the steps of the cycle. The energy from ATP and NADPH is transformed into the chemical bonds of glucose.

Why do light-dependent and light-independent reactions take place only in the light? However, it needs the products of the light-dependent reaction (ATP and NADPH), so it cannot continue indefinitely without it. In the light-independent reaction, the ATP and NADPH produced by the light-dependent reaction are used to convert carbon dioxide into carbohydrate, e.g., glucose.This happens in a series or reactions called the Calvin cycle.

Chapter 10 - Photosynthesis Thus, light energy is initially converted to chemical energy in the form of two compounds: NADPH, a source of energized electrons (reducing power); and ATP, the versatile energy currency o that the light reactions produce no sugar; that happens in the second stage of photosynthesis, the Calvin cycle.hese two stages of photosynthesis are known as the light reactions (the photo part of photosynthesis) and the Calvin cycle (the synthesis part) (FIGURE 10-4). The light reactions are the steps of photosynthesis that convert solar energy to chemical energy.
