What does a thylakoid do during photosynthesis?
A thylakoid is a sheet-like membrane-bound structure that is the site of the light-dependent photosynthesis reactions in chloroplasts and cyanobacteria. It is the site that contains the chlorophyll used to absorb light and use it for biochemical reactions.
What part of photosynthesis occurs in the thylakoid?
The 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.

Thylakoids. A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy. Photosynthesis. The conversion of light energy to chemical energy that is stored in glucose or other organic compounds; occurs in plants, algae, and certain prokaryotes.
What is the role of thylakoid and stroma during photosynthesis?
The light’s energy is transferred through a series of enzymes in the thylakoid membrane, resulting in the production of two energy-carrying compounds: ATP and NADPH. During this process, water molecules are split and oxygen is given off as a waste material. The second step, the dark reaction, occurs in the stroma.
Which part of photosynthesis does not occur in the thylakoid membrane?
Which part of photosynthesis does NOT occur inside the thylakoid membrane? carbon dioxide and water. carbon dioxide, NADPH, and ATP. At the base of most food chains are autotrophs.
Which one of these reactions occurs during photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
What is the main role of carbon dioxide during the process of photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. … Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
What is the function of the thylakoid in the chloroplast?
Thylakoids are the internal membranes of chloroplasts and cyanobacteria, and provide the platform for the light reactions of photosynthesis.
What is the role of proton in lumen of thylakoid of chloroplast in photosynthesis?
The light-induced electron transfer in photosynthesis drives protons into the thylakoid lumen. The excess protons flow out of the lumen through ATP synthase to generate ATP in the stroma.
What is the description 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.
Which term describes stacks of thylakoids?
Stacks of thylakoids embedded with pigment molecules are called grana. The inner matrix of the chloroplast is called the stroma.
Which equation best summarizes the process of photosynthesis?
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Which reaction takes place in the thylakoid discs of the chloroplast?
The light reaction
The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.Aug 21, 2014

in the thylakoid membranes of chloroplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions of photosynthesis.
Which occurs in the thylakoid quizlet?
Light dependent reactions occur in the thylakoid membrane of the chloroplast.
What is the source of the co2 used in photosynthesis?
Plants extract the carbon dioxide from the air and use it in photosynthesis process to feed themselves. The carbon dioxide enters the leaves of the plant through small pores called stomata. Once the carbon dioxide enters the plant, the process begins with the help of sunlight and water.
What is the purpose of the electron transport chain in the thylakoid membrane quizlet?
The electron transport chain helps to move electrons from PS 2 to PS 1. It makes oxidation-reduction reactions within the photosystems. It also uses energy to bring in hydrogren molecules to make a concentration gradient in the thylakoid compartment, which eventually creates ATP due to ATP synthase.
Which statement best describes what a thylakoid does during photosynthesis quizlet?
Thylakoid enables the light-dependent reaction to occur during photosynthesis. Thylakoid is termed as a membrane-bonded compartment which is found inside of cyanobacteria and chloroplast. They are much known for light-dependent reaction.
Does thylakoid contain Calvin cycle enzymes?
Thus, the present study showed that the sequential enzymes of the Calvin cycle are organized adjacent to the thylakoid membranes. Such organization should provide functional facilitation to light and dark reactions of photosynthesis.
What are the materials needed during photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.Which statement correctly explains the process of photosynthesis in plants?
Answer: (c) in the presence of sunlight, chlorophyll uses water and carbon dioxide to produce carbohydrate.
What are the two reactions in the process of photosynthesis?
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
Which describes the role of carbon dioxide in photosynthesis quizlet?
2 – Hydrogen combines with carbon dioxide to make glucose. Which describes the role of carbon dioxide in photosynthesis? It is a reactant, so it is released by the plant.
What is the main role of carbon dioxide during the process of photosynthesis quizlet?
Carbon Dioxide plays a big role in the Light-Independent phase of photosynthesis. … The light energy, upon entering the chloroplasts, is captured by the chlorophyll inside a grana. Inside the grana some of the energy is used to split water into hydrogen and oxygen – electrons then are used to produce NADPH and ATP.
What is the role of carbon dioxide in photosynthesis and respiration?
These two processes are responsible for the exchange of oxygen and carbon dioxide between living organisms and the environment. Photosynthesis converts carbon dioxide and water into oxygen and glucose. … Cellular respiration converts oxygen and glucose into water and carbon dioxide.
What is the function of lumen in photosynthesis?
The aqueous lumen enclosed by the thylakoid membrane network of the chloroplast is the compartment where molecular oxygen is produced from water during photosynthetic light-dependent reactions.
Why is proton gradient important in photosynthesis?
The proton gradient (ƊpH) functions as an intermediate storage of the harvested light energy and drives ATP synthesis as protons pass across the membrane through the chloroplast cpATP synthase.
How is the proton gradient generated in chloroplasts during photosynthesis?
When the light energy is absorbed by the excited electrons are passed on to the chain of electron carriers present within thylakoid membrane. … This energy is utilised to pump protons from the the thylakoid membrane into the thylakoid space which creates the proton gradient.
Whats the process of photosynthesis?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

4.2.
On the thylakoid membranes, certain pigments and associated proteins are packed together to form units called photosystems. There are two types of photosystems, designated Photosystem I (or PSI) and Photosystem II (or PSII). … In higher plants, both photosystems must cooperate in carrying out photosynthesis.
What is photosynthesis equation?
Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light –> C6H12O6 + 6 O2. … During this process, organisms such as plants go through the light-dependent and light-independent reactions to convert carbon dioxide and water into sugars and oxygen.
