Where in the chloroplast do the light reactions occur?

the thylakoid

The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There water (H₂O) is oxidized and oxygen (O₂) is released. The electrons that freed from the water are transferred to ATP and NADPH.

Where does the Calvin cycle occur in eukaryotes?

The two parts of photosynthesis—the light-dependent reactions and the Calvin cycle—have been described as they take place in chloroplasts.

What occurs in the Calvin cycle?

The Calvin cycle is part of photosynthesis which occurs in two stages. In the first stage chemical reactions use energy from light to produce ATP and NADPH. In the second stage (Calvin cycle or dark reactions) carbon dioxide and water are converted into organic molecules such as glucose.

Where does the Calvin cycle phase occur quizlet?

Where does the Calvin Cycle occur? The Calvin Cycle occurs in the stroma whereas the light reactions occur in the thylakoids.

Where does the Calvin cycle of photosynthesis occur quizlet?

The light-dependent reactions take place in the thylakoid membrane and the Calvin cycle takes place in the stroma. A Photosynthesis and cellular respiration are near-opposite processes. Both photosynthesis and cellular respiration occur in the chloroplasts of a cell.

Where does the Calvin cycle occur Chapter 10?

This takes place in the stroma of the chloroplast. It takes in CO₂ and produces carbohydrate ( glyceraldehyde phosphate or GA3P ). Fig 10.10. The Calvin cycle uses the ATP and NADPH that were produced in the light reactions.

Where does Calvin cycle take place Class 11?

stroma
The Calvin cycle occurs in the stroma of the chloroplast. It uses ATP and NADPH produced during the light reactions to synthesise sugars by fixing CO2.Jul 23 2014

What is biochemical phase of photosynthesis explain the Calvin cycle that occurs in chloroplast?

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.

Which is the best description of the Calvin cycle of photosynthesis?

The Calvin cycle is the “synthesis” part of the photosynthesis the set of reactions that actually convert CO2 to organic carbon compounds.

What happens to CO2 in the Calvin cycle?

What happens to carbon dioxide molecules in the Calvin cycle reactions? carbon dioxide molecules are bonded together with the electrons and H’s from NADPH to form glucose. … cO2 goes in and O2 comes out. it helps to exchange them using simple diffusion.

What are the inputs to the Calvin cycle?

2. The inputs into the Calvin cycle are NADPH ATP and CO₂. 3. The products of the Calvin cycle are NADP⁺ ADP and a sugar.

Where does Calvin cycle or dark reaction occur?

The Calvin cycle is also called the dark reactions or light-independent reactions because it is the part that doesn’t need energy from the sun to happen. The Calvin cycle takes place within the stroma of the chloroplast.

Where does light reaction take place?

the chloroplast
The light reaction occurs in the thylakoids of the chloroplast. When the light hits chlorophyll a get excited to higher energy state followed by a series of reactions. This energy is converted into energy molecules ATP and NADPH by using PS I and PS II.

Where does the Calvin cycle occur in eukaryotes quizlet?

In eukaryotes photosynthesis takes place in chloroplasts: The Calvin cycle takes place in the stroma and the light-harvesting reactions take place in the thylakoid membrane. You just studied 12 terms!

Where are chloroplasts concentrated?

leaf mesophyll
In plants chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).

Where does the Calvin cycle occur in eukaryotes group of answer choices?

The Calvin cycle also differs from gluconeogenesis in where it takes place in photosynthetic eukaryotes. Whereas gluconeogenesis takes place in the cytoplasm the Calvin cycle takes place in the stroma of chloroplasts the photosynthetic organelles.

Is the Calvin cycle part of photosynthesis?

The Calvin cycle is a part of photosynthesis the process plants and other autotrophs use to create nutrients from sunlight and carbon dioxide. The process was first identified by American biochemist Dr.

What occurs in the Calvin cycle quizlet?

The ATP and NADPH produced in the light reactions drive the second stage of photosynthesis the Calvin cycle. In the Calvin cycle carbon dioxide is incorporated into organic compounds a process called carbon fixation. The Calvin cycle produces a compound called G3P. … Photosynthesis occurs in two stages.

Where does the Calvin cycle occur quizlet mastering biology?

The Calvin cycle occurs in the stroma.

Where do the light dependent reactions of photosynthesis occur in the chloroplast quizlet?

The light-dependent reactions take place on the thylakoid membranes (the light is absorbed by the chlorophyll that is embedded in these membranes). The light-independent reactions (also called the Calvin Cycle or the dark reactions) take place in the stroma. The stroma is the fluid that fills the chloroplast.

Is the Calvin cycle the first stage of photosynthesis?

Using the energy carriers formed in the first stage of photosynthesis the Calvin cycle reactions fix CO₂ from the environment to build carbohydrate molecules. An enzyme RuBisCO catalyzes the fixation reaction by combining CO₂ with RuBP.

What is the first stage of photosynthesis in the chloroplast?

The Light Reactions
Photosynthesis Stage I: The Light Reactions. 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.Feb 23 2012

Which of the following is produced by the Calvin cycle during photosynthesis?

C3 photosynthesis

Used by the majority of plants it involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle which goes on to become a sugar called glucose.

What are the membranous sacs found within a chloroplast?

Like mitochondria chloroplasts have outer and inner membranes but within the space enclosed by a chloroplast’s inner membrane is a set of interconnected and stacked fluid-filled membrane sacs called thylakoids (Figure 1). Each stack of thylakoids is called a granum (plural = grana).

Where is the stroma located in the chloroplast?

Stroma in botany refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid) and the sub-organelles or daughter cells where photosynthesis is commenced before the chemical changes are completed in the stroma.

Does the Calvin cycle have a electron transport chain?

Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH which temporarily store chemical energy. … The Calvin cycle reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.

Where does carbon fixation occur in chloroplast Class 11?

The carbon-fixation pathway begins in the mesophyll cells where carbon dioxide is converted into bicarbonate which is then added to the three-carbon acid phosphoenolpyruvate (PEP) by an enzyme called phosphoenolpyruvate carboxylase.

What does the chloroplast do during the process of photosynthesis?

Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.
