Stage I is called the light reactions. This stage uses water and changes light energy from the sun into chemical energy stored in ATP and NADPH (another energy-carrying molecule).
Where is energy stored after photosynthesis?
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).
What is produced in the first stage 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 first stage of photosynthesis take place?
The first step of photosynthesis occurs in the chloroplasts of plant cells. Light photons are absorbed by a pigment called chlorophyll, which is abundant in the thylakoid membrane of each chloroplast.
Where is chemical energy stored?
Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy.
Where is energy stored in leaves?
Hi, Plants store their energy in the form of starch, which is a complex carbohydrate that can be broken down into a simple carbohydrate (glucose) for the plant to use for energy. Plant cells store starch in storage organelles like all cells do.
What is the name of the second stage of photosynthesis?
Carbon atoms end up in you, and in other life forms, thanks to the second stage of photosynthesis, known as the Calvin cycle (or the light-independent reactions).
What is the chemical reaction in 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.
What two energy storage molecules are formed during the first phase of photosynthesis?
During the first stage of photosynthesis, called the light-dependent reaction, sunlight excites the electrons in the chlorophyll pigment. The organism uses this energy to create the energy carrier molecules ATP and NADPH, which are crucial for carbon fixing during the second stage.
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.
Where are the phases of photosynthesis?
The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
Where is chemical energy stored in plants?
Photosynthesis is the process plants and some algae use to convert light energy to chemical energy stored as sugar within chloroplasts — the energy factories found in plant cells.
Which of the following are examples of chemical energy being released or stored?
Examples of matter containing chemical energy include: Coal: Combustion reaction converts chemical energy into light and heat. Wood: Combustion reaction converts chemical energy into light and heat. Petroleum: Can be burned to release light and heat or changed into another form of chemical energy, such as gasoline.
Where is chemical energy stored in ATP?
Energy is stored in the covalent bonds between phosphates, with the greatest amount of energy (approximately 7 kcal/mole) in the bond between the second and third phosphate groups. This covalent bond is known as a pyrophosphate bond.
