Schematic of the light-dependent reactions and Calvin cycle and how they’re connected. The light-dependent reactions take place in the thylakoid membrane.There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle

Calvin cycle
The Calvin cycle Calvin–Benson–Bassham (CBB) cycle reductive pentose phosphate cycle (RPP cycle) or C3 cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms. … This set of reactions is also called carbon fixation.

What are the phase of photosynthesis?

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).

Where does Phase 2 of photosynthesis occur?

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.

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 phase of the photosynthetic process?

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 are the 2 stages of photosynthesis and where do they occur?

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.

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.

What are the two phases of photosynthesis Class 11?

Photosynthesis takes place in two stages namely light-dependent reactions and light-independent reactions.

What are the two stages of photosynthesis and where does each one occur in the chloroplast quizlet?

The two stages of photosynthesis are light reactions and the Calvin Cycle. Light reactions occur within the thylakoids and the Calvin Cycle takes place in the stroma. The light reactions create ATP and NADPH which are used by the Calvin Cycle which also brings in carbon to produce sugar.

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.

What are the 3 types of photosynthesis?

The three main types of photosynthesis are C3 C4 and CAM (crassulacean acid metabolism). In college I had to memorize some of their pathways and mechanisms but I will highlight what gives one an advantage over another and what types of crops forages and weeds have specialized C3 and C4 photosynthesis.

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 are the two stages in photosynthesis Class 10?

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

What is photosynthesis class 4th?

Photosynthesis is the process in which green plants use chlorophyll sunlight carbon dioxide and water to make their own food. … Photosynthesis is the process in which green plants use chlorophyll sunlight carbon dioxide and water to make their own food.

What is photosynthesis for class 7th?

The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis. The process of photosynthesis takes place in the leaves of a plant.

What is class 3 photosynthesis?

Photosynthesis is a process in which green plants use energy from the sun to transform water carbon dioxide and minerals into oxygen. Photosynthesis gives us most of the oxygen we need in order to breathe.

How do you differentiate the phases of photosynthesis?

Photosynthesis comprises two phases: The first phase is the photochemical phase or light-dependent process. This phase is commonly known as the light reaction.

Difference between Light and Dark Reaction.
Light Reaction Dark Reaction
It is a photochemical phase. It is a biochemical phase.

What 2 products of the light reactions are used up in the Calvin cycle?

What two products of the light reactions are used up in the calvin cycle? NADPH which is an electron carrier and can be reused and ATP or ADP which is an energy molecule that can be rebuilt in another light reaction.

What are the two sets of reactions for photosynthesis quizlet?

Photosynthesis can be divided into two sets of reactions – the Light Dependent reactions and the Calvin Cycle (also known as the light independent reactions.

What’s the difference between 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 steps or phases in dark respiration?

The Calvin cycle has three main steps: carbon fixation reduction and regeneration.

What types of plants do photosynthesis?

Rather plants use sunlight water and the gases in the air to make glucose which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants algae and even some microorganisms.

What is C3 and C4 cycle?

C3 and C4 cycle are two parts of the overall photosynthesis process. More preciously these are two sections of the biosynthesis process. In this process plants use water and carbon dioxide to make carbohydrate.

What are the two specific steps where ATP is used?

Glycolysis: what are the two specific steps where ATP is used? Glycolysis: the second step in glycolysis the energy payoff phase. note that it provides both ATP and NADH.

What are the 3 phases of the cellular respiration process?

Aerobic respiration is divided into three main stages: Glycolysis Citric acid cycle and Electron transport chain. Glycolysis: Glucose ( 6 carbon atoms) is split into 2 molecules of glyceraldehyde phosphate (3 carbon each) then these are turned into pyruvate (3 carbons each).

What are the three stages of glycolysis?

The glycolytic pathway can be divided into three stages: (1) glucose is trapped and destabilized (2) two interconvertible three-carbon molecules are generated by cleavage of six-carbon fructose (3) ATP is generated.

What are the five steps of photosynthesis?

Terms in this set (7)
  • Step 1-Light Dependent. CO2 and H2O enter the leaf.

What are the 4 main steps of photosynthesis?

The overall process of photosynthesis can be objectively divided into four steps/ process:
  • Absorption of light. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts. …
  • Electron Transfer. …
  • Generation of ATP. …
  • Carbon Fixation.

What is germination 5th class?

Answer: The process by which a seed grows into a new plant is called germination. When the seed get all the necessary things like air water warmth space and nutrients from the soil the process of germination starts. During the early stages the seeds will get food from the cotyledons.

What is photosynthesis in biology class 9?

Photosynthesis is a physiological process by which plant cells containing chlorophyll produce food in the form of carbohydrates by using carbon dioxide water and light energy. Oxygen is released as a by-product.

What is photosynthesis in biology class 11?

Photosynthesis is a process in which the light energy obtained from the sunlight is used in the manufacture of oxygen and sugar molecules in the presence of carbon dioxide and water.

What is photosynthesis 5th answer?

Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Without it there would be no green plants and without green plants there would be no animals. Photosynthesis requires sunlight chlorophyll water and carbon dioxide gas.

What is seed germination class 2?

Germination Germination is defined as the beginning of growth. The term is most commonly associated with plants describing the process of a seed sprouting into a seedling. The term germination can also be applied to spores or buds. When seeds are dry and hard they are dormant.
