Is electron transport chain light-dependent or independent?

The light-dependent reactions involve two photosytems (II and I) and an electron transport chain that are all embedded in the thylakoid membrane.

Where do light-independent reactions occur?

The light-independent reactions represent the known Calvin–Benson–Bassham (CBB) cycle which takes place in the stroma of chloroplasts and is the primary pathway of carbon fixation of C3 plants [119].

Where do the light-independent reaction of photosynthesis occur and why?

In plants, carbon dioxide (CO₂) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO₂ diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.

Does the electron transport chain require light?

The light-dependent reactions take place in the thylakoid membrane, inside chloroplasts. Since they are light 'dependent' reactions, you can guess that these reactions need light to work.

What occurs in light-independent reactions?

The light-independent reactions of photosynthesis take place within the stroma. ... These reactions occur when the pigment chlorophyll, located within the thylakoid membranes, captures energy from the sun (photons) to initiate the breakdown of water molecules.

How does the electron transport chain work in light-dependent reactions?

In the first part of photosynthesis, the light-dependent reaction, pigment molecules absorb energy from sunlight. ... Energy travels through the electron transport chain, which pumps hydrogen ions into the thylakoid space. This forms an electrochemical gradient.

What provides electrons for the light reactions?

Light reactions occur when plants synthesize food from carbon dioxide and water, referring specifically to the part of energy production that requires light and water to generate electrons needed for further synthesis. Water provides the electrons by splitting into hydrogen and oxygen atoms.

What is the light independent process?

The light independent process (also called dark reactions or the Calvin-Benson cycle) takes place in the stroma of the chloroplast. Carbon dioxide is modified by series of chemical reactions to form carbohydrates. The energy for these reactions comes from ATP and NADPH generated during the light dependent process.

Do light-independent reactions require sunlight?

The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process. Although the light-independent reactions do not use light as a reactant (and as a result can take place at day or night), they require the products of the light-dependent reactions to function.

Does the light independent reaction occur in the dark?

There are three phases to the light-independent reactions, collectively called the Calvin cycle: carboxylation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Though it is called the "dark reaction", the Calvin cycle does not actually occur in the dark or during night time.

What is the difference between light dependent and light-independent reactions?

In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

Why should the light dependent reaction occur before the light independent reaction?

In light dependent photosynthesis, the photosynthetic pigment absorb the light energy and convert it into chemical energy, ATP and NADPH,. ... So the light dependent reaction should occur before the light independent reaction.

What is required for both the light dependent and light independent reactions to proceed?

Light dependent reactions occur in Grana of Chloroplasts, Light Independent reactions occur in Stroma of Chloroplasts. Hence Chloroplasts are required for both the light-dependent and light-independent reactions to proceed. Elaine C. The answer is energy.

Which of the following is not required by the light independent reaction?

Complete answer: Calvin cycle is a dark reaction which means it is a light-independent cycle. It occurs in the absence of light during night time. It also occurs during daytime but the energy from sunlight is not needed by it to perform its function.

Which of the following occurs during the light dependent reactions?

In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.
