What are the two stages of photosynthesis?
While there are many steps behind photosynthesis, it can be broken down into two main steps: light-dependent reactions and light-independent reactions.Oct 24, 2019
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. The light-dependent reactions that take place in the thylakoid membrane use light energy to produce ATP and NADPH. The Calvin cycle that takes place in stroma uses the energy from these compounds to make GA3P from CO2.
What are the stages of photosynthesis in order?
It is convenient to divide the photosynthesis process in plants into four stages, each of which takes place in a specific area of the chloroplast: (1) light absorption, (2) electron transport leading to the reduction of NADP + to NADPH, (3) ATP generation, and (4) CO2 conversion to carbohydrates (carbon bonding).
What are the two steps in the photosynthesis quiz?
What are the two stages of photosynthesis? 1= light reactions / light dependent reactions. 2 = Calvin cycle / light independent reactions.
Where does stage 2 of photosynthesis take place?
The two stages of photosynthesis: Photosynthesis has two stages: the light-dependent reactions and the Calvin cycle (light-independent reactions). The light-dependent reactions that take place in thylakoids membraneuse light energy to make ATP and NADPH.
What is the first stage of photosynthesis?
The first stage of photosynthesis is absorption of light energy and loss of electrons from chlorophyll. Photosynthesis is the process by which a plant produces food by absorbing light of a certain wavelength and is used to convert water, carbon dioxide and minerals into oxygen-rich and energetic organic compounds.
What are the 3 stages of photosynthesis?
The three events that occur during photosynthesis are: (i) The absorption of light energy by chlorophyll. (ii) Converting light energy into chemical energy and splitting water into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.
What happens in the second phase of the Photosynthesis Quizlet?
The second phase of photosynthesis is called light independent reaction (or Calvin cycle). … Absorb light energy and generate ATP and NADPH.
What two phases of photosynthesis can be divided into the quizlet?
Concepts in this kit (54) Photosynthesis can be divided into two stages: light-dependent reactions and the Calvin cycle. The light-dependent reactions take place in the thylakoids membrane and the Calvin cycle takes place in the stroma.
What happens in the second step of the Photosynthesis quizlet?
* The second stage of photosynthesis is called light independent reactions and takes place at framework. This is where the energy from stage 1 is used to build glucose.
What are the two phases of class 11 photosynthesis?
Photosynthesis takes place in two stages, namely light-dependent reactions and light-independent reactions.
What happens in the second stage of photosynthesis?
The second stage of photosynthesis is glucose production from carbon dioxide. This process occurs in a continuous cycle named after its discoverer, Melvin Calvin. … Together with carbon dioxide, they are used to produce glucose (sugar) in a process known as the Calvin cycle.
Where does the first stage of photosynthesis take place?
The first stage of photosynthesis takes place in plant cell chloroplasts. The photons of light are absorbed by a pigment called chlorophyll, which is abundant in the thylakoid membrane of each chloroplast.
What are the 5 stages of photosynthesis?
Terms in this set (7)
- Step 1 – Dependent on light. CO2 and H2O go to the leaf.
- Step 2- Dependent on light. Light hits the pigment in the thylakoid membrane, splitting the H2O into O2.
- Step 3 – Dependent on light. The electrons go down to the enzymes.
- Step 4 – Dependent on light. …
- Step 5 – Light independent. …
- Step 6 – Light independent. …
- calvin cycle.
What is the first step in electron transport?
1) In the first step of the ETC, NADH molecule reaches the protein complex I, also known as NADH dehydrogenase. Complex I gains two electrons from NADH by oxidizing it to NAD +. One hydrogen is pumped into the intermembrane space for each electron. This gives a total of two hydrogens per NADH molecule.
What is the term for the two-phase anabolic pathway in which light energy is converted into chemical energy?
Cellular Energy Vocabulary
| Deadline | Definition |
|---|---|
| Photosynthesis | A two-phase anabolic pathway in which the Sun’s light energy is converted into chemical energy for use by the cell. |
| Cellular respiration | A catabolic pathway by which organic molecules are broken down to release energy for use by the cell. |
What is the Calvin cycle in photosynthesis?
The Calvin cycle is the process by which plants and algae convert carbon dioxide from the air into sugar, food autotrophs need to grow. … The energy to drive the chemical reactions in this sugar-making process is provided by ATP and NADPH, chemicals that contain energy plants captured from sunlight.
What is the first step in the Photosynthesis quizlet?
The first step in photosynthesis is light absorption. Plants have special organelles for capturing light energy called chloroplasts.
Where does the first stage of photosynthesis in the quizlet take place?
Where does the first stage of photosynthesis take place? Photosynthesis first occurs in thylakoids membrane in gralight-dependent photosynthetic reactions take place inside the play.
What is the order of photosynthesis steps in grade 10?
The stages of photosynthesis can be summarized by the following equation: 6 CO2 (carbon dioxide) + 6 H2O (water) + Energy = C6H12O6 (glucose) + 6 O2 (oxygen). Carbon from carbon dioxide combines with hydrogen and oxygen from water to make glucose, with oxygen and water as by-products.
What is Class 4 Photosynthesis?
Photosynthesis is the process by which green plants use chlorophyll, sunlight, carbon dioxide and water to make their own food. … Photosynthesis is the process by which green plants use chlorophyll, sunlight, carbon dioxide and water to make their own food.
What are the class 10 stages of photosynthesis?

What are the 3 stages of the Calvin cycle?
Calvin cycle reactions
The Calvin cycle reactions can be divided into three main stages: carbon bond, reduction and regeneration of the starting molecule.
What are the two basic functions of the electron transport chain?
Explanation: The electron transport chain is mainly used send protons across the membrane to the intermembrane space. This creates a proton driving force that will drive ATP synthase in the final stage of cellular respiration to make ATP from ADP and a phosphate group.
What are the highlights at ETC?
Events in the electron transport chain include: NADH and FADHwhich act as electron transporters as they flow through the inner space of the membrane. In complex I, electrons pass from NADH to the electron transport chain, where they flow through the remaining complexes. In this process, NADH is oxidized to NAD.
In what order do the electrons travel through the ETC?
The electrons must travel through special proteins stuck in the thylakoids membrane. They pass through the first special protein (photosystem II protein) and down the electron transport chain. Then they pass through second special protein (protein of photosystem I).
Is photosynthesis anabolic or catabolic?
Photosynthesis, which builds sugars from smaller molecules, is “Structure” or anabolic, pathway. In contrast, cellular respiration breaks down sugar into smaller molecules and is a “degrading” or catabolic pathway.
Why do anabolic pathways require energy?
Anabolic pathways require input energy to synthesize complex molecules from simpler ones. … The molecular energy stored in the bonds of complex molecules is released on catabolic pathways and collected in such a way that it can be used for the production of ATP.
What is the anabolic pathway that converts solar energy into chemical energy for use by cells?
Photosynthesis is an anabolic pathway in which the light energy from the Sun is converted into chemical energy for the cell to use.
Why is the Calvin cycle called the C3 cycle?
The most common set of carbon binding reactions is found in the C3 plants, which are so named since the main stable intermediate is the 3-carbon molecule, glyceraldehyde-3-phosphate. These reactions, best known as the Calvin cycle (Fig. 6.2.
