What are the reactants of the light dependent reaction?

Explanation: Light dependent reactions convert solar energy to chemical energy (in the form of ATP and NADPH). Sunlight and H2O are the reactant of the light dependent reaction.

What is the reactant and product for the light-dependent step?

The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.

What are the steps of light-dependent reactions?

Here are the basic steps:

  • Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center.
  • ATP synthesis.
  • Light absorption in PSI.
  • NADPH formation.

What are the reactants of the Calvin cycle?

In the Calvin cycle, carbon atoms from CO2​start text, C, O, end text, start subscript, 2, end subscript are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions.

What are the reactants and products of photosynthesis?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What are the reactants and products 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 are the reactants involved in 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 are the reactants and products of light independent dark reactions?

Difference between Light and Dark Reaction

Light Reaction Dark Reaction
NADP utilizes H+ ions to form NADPH. The hydrogen of NADPH combines with CO2.
The end products are ATP and NADPH. Glucose is the end product. ATP and NADPH help in the formation of glucose.

What are the reactants in photosynthesis?

What are the steps of light independent reactions?

Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.

What are the steps of the light reaction?

A record-smashing breakthrough in the small town of Cullham, England has gotten mankind one big step closer to the elusive clean energy creates and sustains a controlled nuclear fusion reaction: “The power of the sun in the palm of my hand.”

What is needed for the light independent reaction?

The light-dependent reactions require light and water, occur in the thylakoids, and produce ATP and NADPH. The light-independent reactions require carbon dioxide, occur in the stroma, and produce high-energy sugars.

What is the difference between light independent and dependent reactions?

Both processes produce energy in the form of ATP.

  • Also,both are enzyme-mediated.
  • Furthermore,both take place in chloroplasts.
  • Moreover,both processes take place in autotrophic organisms.
