What are the reactants of photosynthesis?

Photosynthesis is a series of chemical reactions that convert carbon dioxide and water into glucose (sugar) and oxygen in the presence of sunlight.

What is the equation for photosynthesis GCSE?

Equation: carbon dioxide + water —(with light energy)—> glucose + oxygen Glucose is the important product of the photosynthesis reaction.

What are the steps in the process 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).

Is photosynthesis endothermic or exothermic?

Photosynthesis requires energy to drive the chemical reaction. Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves.

What are the 3 reactants you need for photosynthesis?

Photosynthesis: Reactants and Products

• Photosynthesis is the process plants use to make their own food.
• The reactants of photosynthesis are carbon dioxide and water.
• Light energy from the sun initiates photosynthesis in the chloroplasts of plant cells.
• The products of photosynthesis are glucose and oxygen.

What brings energy to a plant?

Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).

Where do plants get their mass?

So where does the mass come from? The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun’s energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

What are the two main stages of photosynthesis?

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

What is photosynthesis explain with diagram?

photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

What is photosynthesis formula?

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.

Is photosynthesis is an example of an exothermic reaction?

Photosynthesis is an endothermic reaction. The source of the energy for the formation of glucose is light (radiant energy), usually from the sun. Thus, green plants have the remarkable ability to trap the energy of sunlight and use that energy to produce glucose from carbon dioxide and water.

How is gaseous oxygen released in photosynthesis?

Photosynthesis is a process which synthesizes carbohydrates ( glucose) from water and carbon dioxide, utilizing the energy from sunlight by green plants, algae, and cyanobacteria. As a result of photosynthesis, gaseous oxygen is released to the environment. It is an extremely important process for the existence of life on earth.

How does oxygenic photosynthesis help in carbon fixation?

Oxygenic photosynthesis, provides energy to organism and allows for carbon fixation, all the while producing oxygen as a byproduct. Plants, algae and cyanobacteria release oxygen during photosynthesis. Photosynthesis is also needed for carbon fixation.

What is the difference between anoxygenic and oxygenic photosynthesis?

Oxygen is not released or generated. Organisms. Oxygenic photosynthesis is shown by cyanobacteria, algae, and green plants. Anoxygenic photosynthesis is mainly shown by purple bacteria, green sulfur and nonsulfur bacteria, heliobacteria, and acidobacteria.

Which is the reaction center of oxygenic photosynthesis?

Due to the generation of molecular oxygen, this process is known as oxygenic photosynthesis and also called noncyclic photophosphorylation. Oxygenic photosynthesis has two photosystems named PS I and PS II. These two photosynthetic apparatus contain two reaction centers P700 and P680.
