What happens to the light energy used as a reactant in photosynthesis?

Photosynthesis is the process by which plants, and some bacteria, use solar energy to produce sugar. This process converts light energy to chemical energy, which is stored in the sugars.

What happens after the light reactions in photosynthesis?

During the light reactions of photosynthesis, light from the sun is captured through a series of reactions involving the chemical chlorophyll. … ATP and NADPH are used subsequently to produce glucose from CO2 in the next phase of photosynthesis, the dark reactions.

Why light is included as a reactant in photosynthesis?

Light provides energy for the synthesis of glucose from carbon dioxide and water during photosynthesis. … During light reaction, the chlorophyll entraps light and the solar energy is converted into chemical energy in the form of ATP molecules. This can happen because light energy is used to split water.

What are the reactants and products of the light reactions of photosynthesis?

During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Does respiration expend more energy than photosynthesis?

Respiration releases the energy contained in sugars for use in metabolism. This process is not balanced because the oxygen used for respiration is much less than what is given off during the photosynthetic reaction and the carbon dioxide given off is much less than what is taken up during photosynthesis.

NEED TO KNOW:  Are electric bikes OK in the rain?

What is the relationship between water light and co2 and photosynthesis?

Light provides the energy for photosynthetic pigments to convert carbon dioxide (CO2) and water into sugars and oxygen. As light intensity increases Ð until a point Ð the amount of sugars increases and thus, more energy is available for plant growth and maintenance.

What are the end products of light reaction?

What are the end products of light reactions?

  • Hint: The process of using the energy in sunlight to make food (glucose) is known as photosynthesis. …
  • Complete answer: …
  • Therefore, the end products are ATP and NADPH.
  • Note: The ATP and NADPH from the light-dependent reactions are used to make sugars in the Calvin cycle.

Will photosynthesis occurs in the absence of light?

Both photosynthesis and respiration occur within plant cells. … At night, or in the absence of light, photosynthesis in plants stops, and respiration is the dominant process. The plant uses energy from the glucose it produced for growth and other metabolic processes.
