What else can I help you with?
Is the stroma located within the thylakoid membrane?
No, the stroma is not located within the thylakoid membrane. The stroma is the fluid-filled space outside the thylakoid membranes in the chloroplast.
How many phospholipid bilayers separate the stroma from the thylakoid lumen?
There is only 1 phospholipid bilayer that separates the stroma from the thylakoid lumen.
What are the names of the sacs where photosynthesis takes place?
Photosynthesis takes place in structures called chloroplasts, which contain sac-like structures called thylakoids. Thylakoids are arranged in stacks called grana, where the light-dependent reactions of photosynthesis occur.
Where is the thylakoid membrane located within a plant cell?
The thylakoid membrane is located within the chloroplast of a plant cell.
What accumulates inside of the thylakoid compartment?
Protons accumulate inside the thylakoid compartment during photosynthesis. This gradient is essential for the production of ATP through ATP synthase.
What are stacks of hollow disks formed of thylakoid membrane in a chloroplast?
grana
What are the little stacks of disks that make up the the thylakoid membrane system?
They are called granum, plural: grana
Where in the chloroplast do light reactions occur?
Light reactions occur in the thylakoid membranes of the chloroplast. Pigment molecules such as chlorophyll absorb light energy and transfer it to reaction center proteins, initiating a series of electron transfer reactions that generate ATP and NADPH as energy carriers for the Calvin cycle.
What are stacks of disks containing chlorophyll in a chloroplast called?
The stacks of disks containing chlorophyll in a chloroplast are called thylakoids. Thylakoids are membrane-bound compartments where the light-dependent reactions of photosynthesis occur. Multiple thylakoids are usually stacked on top of each other to form grana.
Which compartment in chloroplasts is likely to have the lowest pH?
The thylakoid lumen is likely to have the lowest pH in chloroplasts due to the accumulation of protons during the light-dependent reactions of photosynthesis.
What are thylakloids?
A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of athylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum). Grana are connected byintergrana or stroma thylakoids, which join granum stacks together as a single functional compartment.
What is the function of the proton pumps in the thylakoid membranes?
Proton pumps in the thylakoid membranes of chloroplasts create a proton gradient by pumping H+ ions from the stroma into the thylakoid lumen during photosynthesis. This gradient is utilized by ATP synthase to produce ATP through chemiosmosis.
Is chlorophyll found in the thylakoid membrane or in the thylakoid space?
Chlorophyll is found in the thylakoid membrane.
Is the stroma located within the thylakoid membrane?
No, the stroma is not located within the thylakoid membrane. The stroma is the fluid-filled space outside the thylakoid membranes in the chloroplast.
How many phospholipid bilayers separate the stroma from the thylakoid lumen?
There is only 1 phospholipid bilayer that separates the stroma from the thylakoid lumen.
What happens in the thylakoid membranes?
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 intergrana or stroma thylakoids, which join granum stacks together as a single functional compartment.
What are the flatened sacks in the chloroplasts that contain chlorophyll?
granum = stacks of thylakoid the thylakoid are the flattened sacks
