What a thylakoid does during photosynthesis?
Thylakoid is the site of photochemical or light-dependent reactions of photosynthesis. Chlorophyll present in the thylakoid membrane absorbs energy from the sunlight and is involved in the formation of ATP and NADPH in the light reaction of photosynthesis through electron transport chains.
What is the function of the thylakoid?
The principal functions of thylakoids are the trapping of light energy and the transduction of this energy into the chemical energy forms, ATP and NADPH. During this process, water is oxidized and oxygen is released.
How would you describe a thylakoid?
Definition of thylakoid : any of the membranous disks of lamellae within plant chloroplasts that are composed of protein and lipid and are the sites of the photochemical reactions of photosynthesis.
What statement best describes the process of photosynthesis?
Which statement best describes the relationship of photosynthesis and energy? A) The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.
What are thylakoids what function do they have in photosynthesis quizlet?
The chloroplasts' membranous sacs (thylakoids), are the site of photosynthetic light reactions and involves the transfer of electrons from a photoexecuted state from the chlorophyll inside the thylakoid membranes to the stroma, which then produces ATP.
What are thylakoids quizlet?
thylakoids. One of a number of disk-shaped membranous sacs inside a chloroplast. Thylakoid membranes contain chlorophyll and the enzymes of the light reactions of photosynthesis. A stack of thylakoids is called a granum.
Where is the thylakoid?
chloroplasts Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis.
Which process occurs during photosynthesis quizlet?
In the process of photosynthesis, plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.
What happens in the thylakoid quizlet?
in the thylakoid membranes of chloroplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions of photosynthesis.
What do the thylakoids of a chloroplast make up quizlet?
thylakoid disks are disk-shaped membrane structures in chloroplasts that contain chlorophyll. Chloroplasts are made up of stacks of thylakoid disks; a stack of thylakoid disks is called a granum. Photosynthesis (the production of ATP molecules from sunlight) takes place on thylakoid disks.
What are thylakoids and their function in photosynthesis quizlet?
The chloroplasts' membranous sacs (thylakoids), are the site of photosynthetic light reactions and involves the transfer of electrons from a photoexecuted state from the chlorophyll inside the thylakoid membranes to the stroma, which then produces ATP.
What is thylakoids part of quizlet?
thylakoid. A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy. grana.
What do the thylakoids of a chloroplast make up?
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/stromal thylakoids, which join granum stacks together as a single functional compartment.
Which of the following occurs during photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Which of the following happens during photosynthesis?
Explanation: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. … This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
What stage of photosynthesis occurs in the thylakoids?
The light-dependent reactions of photosynthesis take place within the thylakoids. 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.
What is photosynthesis describe site of photosynthesis?
Photosynthesis takes place in special organelles known as chloroplast. This organelle has its own DNA, genes and hence can synthesize its own proteins. Chloroplasts consist of stroma, fluid, and stack of thylakoids known as grana.
Which of the following takes place in thylakoids?
The chloroplast is involved in both stages of photosynthesis. The light reaction takes place in the thylakoid discs.
What is inside thylakoid?
Thylakoids are usually arranged in stacks (grana) and contain the photosynthetic pigment (chlorophyll). The grana are connected to other stacks by simple membranes (lamellae) within the stroma, the fluid proteinaceous portion containing the enzymes essential for the photosynthetic dark reaction, or Calvin cycle.
What is the site of photosynthesis quizlet?
Photosynthesis occurs in the chloroplast. What are chloroplasts and where are they found? Chloroplast is an organelle found in the leaves of green plants. They are found in a plant cell.
What is the purpose of the stacks of thylakoid membrane within the chloroplast?
Inside the chloroplasts are stacks of discs called thylakoids. They are compared to stacks of coins within the walls of the chloroplast, and they act to trap the energy from sunlight.
How does the thylakoid aid in energy capture?
The stacks of thylakoids are called grana. They are connected with an extensive sytem of tubules. The thylakoid membranes contain chlorophyll and other pigments arranged in antenna arrays to capture light energy for two photosystems called Photosystem I and Photosystem II.
Which occur in the thylakoids?
Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.
Which photosynthetic reactions occur in the thylakoid membranes of the Grana quizlet?
Photosynthesis first occurs in the thylakoid membrane within the grana, inside the grana the light-dependent reactions of photosynthesis occur.
Does thylakoid contain chlorophyll?
The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma (Figure 3, Figure 4).
What is the significance of the thylakoid membrane?
Thylakoid membranes contain integral membrane proteins which play an important role in light-harvesting and the light-dependent reactions of photosynthesis.
Which of the following occurs in the thylakoid quizlet?
Which of the following processes occurs in the thylakoid membrane and converts captured light energy into chemical energy? chemiosmosis. providing the energy to produce ATP molecules.
Which part of photosynthesis occurs in the thylakoid membranes?
light-dependent reactions The light-dependent reactions of photosynthesis take place within the thylakoids. 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.
What happens in the thylakoids of the chloroplast?
Much of the light gathering and light dependent reactions occur here in the thylakoid. In the thylakoid membrane itself, two light reactions occur: photosystem I and II. In each photosystem there are different proteins and slightly different chlorophyll pigments that allow for different light absorption.
Which statement correctly describes the process that occurs in the thylakoid?
Which statement correctly describes the process that occurs in the thylakoid? ATP is produced in the thylakoid during light-independent reactions.
