How is light energy converted to ATP during photosynthesis?

During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. … Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP. The third phosphate chemical bond contains the new chemical energy.

How is ATP produced in photosynthesis?

In an intact chloroplast with thylakoid membranes, ATP is generated by an electron flow along the cytochrome transport system. Since the electrons are being transported to other “carrier” molecules, their energy is used to generate ATP and no reddish glow is emitted.

During what stage of photosynthesis is light energy converted into ATP?

The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

How is photosynthesis energy converted?

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Where is light energy converted into an electron flow?

the reaction center is where light energy is converted into electron transport.

Which process occurs during the light-dependent reactions in photosynthesis?

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. … Each water molecule breaks down into two hydrogen (H) atoms and one oxygen (O) atom.

What happens during light phase of 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.

What is the role of light energy in photosynthesis?

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 the role of light energy in photosynthesis quizlet?

In the presence of light, plants transform carbon dioxide and water into carbohydrates, and they also release oxygen. … What is the role of light and chlorophyll in photosynthesis? Light is a form of energy and chlorophyll absorbs light and the energy from the light.

How does energy get transformed by plants?

In this case plants convert light energy (1) into chemical energy, (in molecular bonds), through a process known as photosynthesis. Most of this energy is stored in compounds called carbohydrates. The plants convert a tiny amount of the light they receive into food energy.

How do plants turn sunlight into energy in scientific terms?

Plants convert sunlight into usable energy through the process of photosynthesis. Light energy from the photons strikes the chlorophyll in the leaves which causes a chemical reaction between the chlorophyll carbon dioxide and water creating C6H12O6 or sugar.

What produces only ATP using energy from electrons energized by light?

The production of ATP in the chloroplast is called photophosphorylation because the energy harnessed in the process originally came from light. This process of ATP production is called non-cyclic photophosphorylation.

Where does the light reaction of photosynthesis take place?

The chloroplast is involved in both stages of photosynthesis. The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH.

Where does the light reaction in photosynthesis occur quizlet?

– The light reactions take place inside the thylakoids of chloroplasts.
