Photosynthesis takes place in two sequential stages: The light-dependent reactions; The light-independent reactions , or Calvin Cycle.
What are the two kinds of reactions in photosynthesis Brainly?
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions) . Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
What are the 2 types of reactions in photosynthesis?
The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle), which take place in the stroma.
What are the reactions of photosynthesis?
The process of photosynthesis is commonly written as: 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2 . 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.
What are the two kinds of reaction?
- Synthesis reactions. Two or more reactants combine to make 1 new product. ...
- Decomposition reactions. A single reactant breaks down to form 2 or more products. ...
- Single-replacement reactions. ...
- Double-replacement reactions. ...
- Combustion 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 produced in dark reactions of photosynthesis?
photosynthesis, Process by which green plants and certain other organisms transform light into chemical energy. ... NADPH and ATP drive the second stage, the dark reaction (or Calvin cycle, discovered by Melvin Calvin), which does not require light. During this stage glucose is generated using atmospheric carbon dioxide .
What are the two types of reactions in 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 CO 2 .
What is the first of two photosynthetic reactions?
Light energy is converted to chemical energy during the first stage of photosynthesis, which involves a series of chemical reactions known as the light-dependent reactions .
What three factors affect photosynthesis?
- Light intensity. Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide. ...
- Carbon dioxide concentration. ...
- Temperature.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
What is the process of photorespiration?
1.1. The Origin and Significance of Photorespiration. Photorespiration is the process of light-dependent uptake of molecular oxygen (O 2 ) concomitant with release of carbon dioxide (CO 2 ) from organic compounds . The gas exchange resembles respiration and is the reverse of photosynthesis where CO 2 is fixed and O 2 released ...
What are 3 examples of a chemical reaction?
Some examples of chemical reactions are combustion (burning), precipitation, decomposition and electrolysis .
How can you identify a chemical reaction?
How can I tell if a chemical reaction is occurring? A chemical reaction is usually accompanied by easily observed physical effects , such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change.
What is the net reaction of photosynthesis?
Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen. Many reactions occur, but the overall chemical reaction for photosynthesis is: 6 CO 2 + 6 H 2 O + light → C 6 H 12 O 6 + 6 O . Carbon Dioxide + Water + Light yields Glucose + Oxygen.
