What Is The Second Stage Of Photosynthesis Called?

the Calvin cycle

What is the second process of photosynthesis?

The process of photosynthesis is divided into two main parts. The first part is called the light dependent reaction. This reaction happens when the light energy is captured and pushed into a chemical called ATP. The second part of the process happens when the ATP is used to make glucose (the Calvin Cycle).

What are the 3 stages of photosynthesis called?

It is convenient to divide the photosynthetic process in plants into four stages each occurring in a defined area of the chloroplast: (1) absorption of light (2) electron transport leading to the reduction of NADP+ to NADPH (3) generation of ATP and (4) conversion of CO2 into carbohydrates (carbon fixation).

Why does photosynthesis have two stages?

Photosynthesis represents the biological process by which plants convert light energy into sugar to fuel plant cells. Comprised of two stages one stage converts the light energy into sugar and then cellular respiration converts the sugar to Adenosine triphosphate known as ATP the fuel for all cellular life.

Where does Stage 2 of photosynthesis occur?

the chloroplast
Photosynthesis Stage II: The Calvin Cycle. The second stage of photosynthesis takes place in the stroma surrounding the thylakoid membranes of the chloroplast. The reactions of this stage can occur without light so they are sometimes called light-independent or dark reactions.Feb 23 2012

What are the 4 stages of photosynthesis?

What are the two stages of photosynthesis and how are they related?

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 are the 5 stages of photosynthesis?

Terms in this set (7)
  • Step 1-Light Dependent. CO2 and H2O enter the leaf.
  • Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid splitting the H2O into O2.
  • Step 3- Light Dependent. The electrons move down to enzymes.
  • Step 4-Light Dependent. …
  • Step 5-Light independent. …
  • Step 6-Light independent. …
  • calvin cycle.

What is the stages of photosynthesis?

Photosynthesis takes place in two sequential stages: The light-dependent reactions The light-independent reactions or Calvin Cycle.

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 is the first stage of photosynthesis called?

light-dependent reactions
Photosynthesis occurs in two stages. In the first stage light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage the light-independent reactions use these products to capture and reduce carbon dioxide.

What is the second step of photosynthesis Class 10?

In the second stage the Calvin cycle takes place. Here carbon dioxide is used to produce glucose. It is a continuously occurring cycle hence the name. In addition to the carbon dioxide the energy that is provisionally accumulated in the ATP and NADPH is also used to generate glucose – the sugar.

What are photosystem 1 and 2?

Photosystem I (PS I) and photosystem II (PS II) are two multi-subunit membrane-protein complexes involved in oxygenic photosynthesis. … The main difference between photosystem 1 and 2 is that PS I absorbs longer wavelengths of light (>680 nm) whereas PS II absorbs shorter wavelengths of light (<680 nm).

What are the two phases of photosynthesis *?

The two stages of photosynthesis are the light reactions and the Calvin cycle.

What are the two stages of cellular respiration?

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis pyruvate oxidation the citric acid or Krebs cycle and oxidative phosphorylation.

What takes place during the second step of photosynthesis referred to as the carbon reactions?

In the second stage of photosynthesis (carbon reactions) the energy of ATP and the electrons in NADPH are used to make glucose from CO2.

What are stages of respiration?

Aerobic respiration is divided into three main stages: Glycolysis Citric acid cycle and Electron transport chain.

Which of the following processes occurs during the second phase of the Calvin cycle?

Reduction. In the second stage ATP and NADPH are used to convert the 3-PGA molecules into molecules of a three-carbon sugar glyceraldehyde-3-phosphate (G3P). This stage gets its name because NADPH donates electrons to or reduces a three-carbon intermediate to make G3P.

How do plants obtain food name the two phases of photosynthesis?

Chlorophyll can make food the plant can use from carbon dioxide water nutrients and energy from sunlight. This process is called photosynthesis. … Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).

What occurs in the second phase of photosynthesis quizlet?

The second phase of photosynthesis is called the light independent reaction (or Calvin Cycle). … absorb light energy and make ATP and NADPH.

What happens in the second stage of photosynthesis quizlet?

*The second stage of photosynthesis is called the light-independent reactions and occurs in the stroma. This is where energy from stage 1 is used to build glucose.

What two phases can photosynthesis be broken down into quizlet?

Terms in this set (54) Photosynthesis can be divided into two steps: the light-dependent reactions and the Calvin cycle. The light-dependent reactions take place in the thylakoid membrane and the Calvin cycle takes place in the stroma.

Which reaction takes place in the stroma 2 of the chloroplast?

photosynthesis

Interior to the chloroplast’s inner membrane and surrounding the thylakoids is a fluid called the stroma. The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose.

What is ADP and NADP?

ATP – Adenosine triphosphate. ADP – Adenosine diphosphate. NADP – Nicotinamide adenine dinucleotide phosphate. NADPH – The reduced form of NADP. In the Light Dependent Processes i.e Light Reactions the light strikes chlorophyll a in such a way as to excite electrons to a higher energy state.

What are the 2 types of photosystem?

There are two types of photosystems in cyanobacteria algae and higher plants called photosystem I (PSI plastocyanin-ferredoxin oxidoreductase) and photosystem II (PSII water-plastoquinone oxidoreductase) both of which are multisubunit membrane complexes.

Why do plants have 2 photosystems?

Due to the large difference in the redox potential between the electron donor (oxygen in a water molecule) and final electron acceptor during the light phase of photosynthesis (NADP+) the ancestor cyanobacteria had to evolve the capability to use two photosystems working in series in order to be able to accumulate the …

Does photosystem 2 come first?

There are two types of photosystems in the light-dependent reactions photosystem II (PSII) and photosystem I (PSI). PSII comes first in the path of electron flow but it is named as second because it was discovered after PSI.

What is the main difference between the 1st and 2nd step of photosynthesis?

Photosynthesis occurs in two stages. During the first stage the energy from sunlight is absorbed by the chloroplast. Water is used and oxygen is produced during this part of the process. During the second stage carbon dioxide is used and glucose is produced.

Where does the second stage of cellular respiration occur?

As you can see from Figure above a mitochondrion has an inner and outer membrane. The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration the Krebs cycle takes place in the matrix.

Where does the second stage of cellular respiration occur WXYZ?

The second stage of cellular respiration the Krebs cycle takes place in the matrix.
