What is produced during light reactions that powers the Calvin cycle?

These electrons are used to produce NADPH as well as ATP in a series of reactions called the light reactions because they require light. NADPH and ATP formed by the action of light then reduce carbon dioxide and convert it into 3-phosphoglycerate by a series of reactions called the Calvin cycle or the dark reactions.

Which molecule is produced during the light reactions of photosynthesis quizlet?

The light reactions produce chemical energy in the form of NADPH and ATP.

What provides the energy for light independent reactions?

Each photosystem plays a key role in capturing the energy from sunlight by exciting electrons. These energized electrons are transported by “energy carrier” molecules which power the light-independent reactions.

What molecule does the PGA molecule turn into during this phase of the Calvin cycle?

PGAL

The PGA molecule loses an oxygen atom as it turns into PGAL.

How chemical energy is formed from light energy during photosynthesis?

During the process of photosynthesis light penetrates the cell and passes into the chloroplast. … Some of the light energy is converted to chemical energy. During this process a phosphate is added to a molecule to cause the formation of ATP. The third phosphate chemical bond contains the new chemical energy.

Which energy is needed in the light-dependent reaction of photosynthesis?

light energy

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

What energy is needed by photosynthetic organisms during the process of photosynthesis?

During the process of photosynthesis cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell such as glucose.

What energy molecule is produced during the light reactions and helps to power the Calvin cycle quizlet?

What two molecules are produced by the light reactions and used to power the Calvin cycle? ATP and NADPH are both products of the light reactions and are used to power the Calvin cycle.

What 2 molecules are produced during the light reactions and used during the Calvin cycle?

The Calvin cycle reactions use chemical energy from NADPH and ATP that were produced in the light reactions.

Which of the following molecules is produced during the light reactions of photosynthesis and used in the Calvin cycle reactions?

The Interworkings of the Calvin Cycle. Figure 1. Light-dependent reactions harness energy from the sun to produce ATP and NADPH. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place.

What source of energy is used in the Calvin cycle?

The Calvin cycle is also sometimes referred to as the “light independent” reactions of photosynthesis since it is not powered directly by photons from the Sun. Instead the Calvin cycle is powered by ATP and NADPH which are created by harnessing the energy from photons in the light-dependent reactions.

Where does the energy for the Calvin cycle come from?

The energy used in the Calvin cycle comes from the ATP and NADPH that are made in the Light Reactions stage of photosynthesis.

Where is the most energy used in the Calvin cycle?

Where is the most energy used in the Calvin cycle? Creating the higher-energy bonds in G3P requires the most energy in the Calvin cycle.

How does the light energy captured in the light-dependent reactions help in the synthesis of glucose and other carbohydrates in the Calvin cycle?

The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. … To replace the electron in the chlorophyll a molecule of water is split.

How many ATP molecules are produced in the Calvin cycle?

18 ATP

The Calvin cycle uses 18 ATP and 12 NADPH molecules to produce one glucose molecule.

Which of these molecules contributes to the energy that is stored in carbohydrate during the Calvin cycle?

Which of these molecules contributes to the energy that is stored in carbohydrate during the Calvin cycle? The products of the Calvin cycle are 3-carbon sugars. In the Calvin cycle ATP is required to: donate a phosphate group to 3-PGA.

What is produced during the light reaction quizlet?

In the light reactions the energy of sunlight is used to oxidize water (the electron donor) to O2 and pass these electrons to NADP+ producing NADPH. Some light energy is used to convert ADP to ATP. The NADPH and ATP produced are subsequently used to power the sugar-producing Calvin cycle.

Which of the following are produced during the light reactions?

Light reactions harness energy from the sun to produce chemical bonds ATP and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation reduction and regeneration.

Which of the following molecules is produced in the light-independent reactions?

Light reactions harness energy from the sun to produce chemical bonds ATP and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation reduction and regeneration.

What happens during a light independent reaction?

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.

What products of the light-dependent reactions are used in the light-independent reactions?

Figure 8.6. 1: The light-dependent reactions of photosynthesis (left) convert light energy into chemical energy forming ATP and NADPH. These products are used by the light-independent reactions to fix CO2 producing organic carbon molecules.

Which molecules provide the energy to reduce PGA?

Light-dependent reactions provide NADPH (electrons) and ATP (energy) to reduce PGA to PGAL.

Where do the ATP and NADPH produced during the light-dependent reactions go when the process is complete? The NADPH and ATP are made in the stroma. These molecules will be used in the Calvin Cycle to make glucose.

What molecule is released during Photorespiration?

Photorespiration is the process of light-dependent uptake of molecular oxygen (O2) concomitant with release of carbon dioxide (CO2) from organic compounds. The gas exchange resembles respiration and is the reverse of photosynthesis where CO2 is fixed and O2 released.

Which chemical reaction occurs during photosynthesis?

photosynthesis the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants light energy is captured and used to convert water carbon dioxide and minerals into oxygen and energy-rich organic compounds.

What substances are produced during photosynthesis?

Photosynthesis is the process by which plants use sunlight water and carbon dioxide to create oxygen and energy in the form of sugar.

What happens to the chemical energy produced by photosynthesis?

Through photosynthesis certain organisms convert solar energy (sunlight) into chemical energy which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work such as cellular respiration.

What is light energy converted into during the light-dependent reactions?

The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules.
