Where does the Calvin cycle of photosynthesis take place 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.

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.

Which are the sites of these phases in chloroplast?

The chloroplast is involved in both stages of photosynthesis. The light reaction takes place in the thylakoid discs. There water (H20) is oxidized and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH.

Where does Calvin Benson cycle occur?

stroma of chloroplasts

A cyclical series of biochemical reactions that occur in the stroma of chloroplasts during photosynthesis.

What are the three phases of the Calvin cycle quizlet?

What are the three phases or steps of the Calvin Cycle? Fixation reduction and regeneration.

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.

Where does light-dependent reaction take place?

chloroplasts
Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.

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 is Calvin cycle in photosynthesis?

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.

Do C3 plants have chloroplasts?

In C3 plants the bundle sheath cells do not contain chloroplasts. In C4 plants the bundle sheath cells contain chloroplasts. In C3 plants the carbon dioxide fixation takes place only at one place. In C4 plants the carbon dioxide fixation takes places twice (one in mesophyll cells second in bundle sheath cells).

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.

What reaction takes place during photosynthesis?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants six carbon dioxide molecules and six water molecules are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules the products.

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 does photosynthesis take place in a eukaryotic cell?

chloroplast
In all phototrophic eukaryotes photosynthesis takes place inside a chloroplast an organelle that arose in eukaryotes by endosymbiosis of a photosynthetic bacterium (see Unique Characteristics of Eukaryotic Cells). These chloroplasts are enclosed by a double membrane with inner and outer layers.

Where in eukaryotic cells does the Calvin cycle take place thylakoid membrane thylakoid lumen chloroplast stroma Granum?

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. The Calvin cycle which takes place in the stroma uses energy derived from these compounds to make GA3P from CO2.

What is chloroplast structure?

Structure of Chloroplasts

Chloroplasts are oval-shaped and have two membranes: an outer membrane and an inner membrane. Between the outer and inner membrane is the intermembrane space approximately 10-20 nm wide. The space within the inner membrane is the stroma the dense fluid within the chloroplast.

What is the output product of the Calvin cycle?

The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These 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 the Calvin Cycle occur quizlet mastering biology?

The Calvin cycle occurs in the stroma.

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

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.

Which energetic process takes place in the chloroplast what are the products of that set of reactions?

photosynthesis

In plants and algae which developed much later photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis NADPH and ATP are used by the photosynthetic cells to produce many organic molecules.

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).
