What happens when thylakoid membrane is damaged?

What happens when thylakoid membrane is damaged?

What affect would a damaged thylakoid membrane have on photosynthesis? The damage would affect the flow of electrons through the mitochondria. The damage to the thylakoid would affect the splitting of the water molecule. The sodium-potassium pump would be affected by a damaged thylakoid.

What is the function of the thylakoid membrane?

Introduction. Thylakoids are the internal membranes of chloroplasts and cyanobacteria, and provide the platform for the light reactions of photosynthesis.

What happens in the thylakoid membranes of the chloroplast?

The thylakoid membranes of a chloroplast is an internal system of interconnected membranes, that carry out the light reactions of photosynthesis. They are arranged into stacked and unstacked regions called grana and stroma thylakoids, respectively, that are differentially enriched in photosystem I and II complexes.

What affect would a damaged thylakoid membrane have on photosynthesis quizlet?

The leaking membrane would cause the diffusion of protons into the stroma, destroying the proton gradient. Because ATP synthesis relies on the proton gradient, the damage prevents ATP from being produced.

What effect would a damaged thylakoid membrane have on photosynthesis quizlet?

The thylakoid membrane becomes damaged, causing the inside of the thylakoid to mix with the stroma. Which of the following processes is likely to be most affected by this damage? CORRECT ANSWER A: The leaking membrane would cause the diffusion of protons into stroma, destroying the proton gradient.

What is the thylakoid membrane?

Definition and Function of Thylakoid Membrane The thylakoids themselves contain the chlorophyll, but the thylakoid membrane, which is the layer that surrounds the thylakoid, is where the light reactions take place. Embedded in the thylakoid membrane are two photosystems, named photosystem I and photosystem II.

How would a mutation in plants that makes the thylakoid membrane permeable to charged ions affect the Calvin cycle?

A mutation occurs in the chloroplasts of a lettuce plant, causing its thylakoid membranes to become more permeable to charged ions. How might this mutation affect the Calvin cycle? Fewer carbohydrates would be produced by the Calvin cycle. There would be no change to the Calvin cycle.

Why is the photosynthesis equation misleading?

The equation for photosynthesis shown above is very misleading. It suggests that changing carbon dioxide and water into carbohydrates is a simple, one-step process. During each of the many stages of photosynthesis, a single atom or an electron is transferred from one compound to another.

What is the role of the thylakoid in photosynthesis?

Role of the Thylakoid in Photosynthesis. Reactions performed in the thylakoid include water photolysis, the electron transport chain, and ATP synthesis. Photosynthetic pigments (e.g., chlorophyll) are embedded into the thylakoid membrane, making it the site of the light-dependent reactions in photosynthesis.

How are the stroma thylakoids connected to the chloroplast?

Higher plants have specially organized thylakoids in which each chloroplast has 10-100 grana that are connected to each other by stroma thylakoids. The stroma thylakoids may be thought of as tunnels that connect the grana. The grana thylakoids and stroma thylakoids contain different proteins.

Which is part of the thylakoid membrane synthesizes ATP?

Thylakoids synthesize ATP using an ATP synthase enzyme that is similar to mitochondrial ATPase. The enzyme is integrated into the thylakoid membrane. The CF1-portion of the synthase molecule extended into the stroma, where ATP supports the light-independent photosynthesis reactions.

Where does the word thylakoid come from and what does it mean?

The word thylakoid is from the Green word thylakos, which means pouch or sac. With the -oid ending, “thylakoid” means “pouch-like.” Thylakoids may also be called lamellae, although this term may be used to refer to the portion of a thylakoid that connects grana.
