Question

Transport of protons from lumen to stroma through CFO Is a​

Answer 1

Answer:

Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum). Grana are connected by intergranal/ stroma thylakoids, which join granum stacks together as a single functional compartment.

Answer 2

Answer:

The transport of protons from lumen to stroma is according to the concentration gradient.

Explanation:

• Protons are transported via the membrane as electrons move through the photosystems.
• This is so because an electron is passed to a H transporter instead of an electron transporter by the principal electron receptor, which is located on the outer side of the membrane.
• When transmitting the electron, this molecule draws the proton from the stroma.
• The proton is released from this molecule on the interior or lumen side of the membrane while the electron is transferred to the electron carrier on the inside of the membrane. The stroma is where these protons come from.
• As a result, within the chloroplast, the lumen receives an increase while the stroma receives a decrease in the number of protons. A proton gradient is subsequently created through the thylakoid membrane.

According to the concentration gradient, the protons are transported from the lumen to the stroma.
