How does the wavelength of light affect photosynthesis?

Photosynthesis can only occur with specific wavelengths of light. The light reacts with the aromatic ring of a specific chlorophyll(different ones in different plants) molecules. The structure of this molecule creates different energy fields for the electrons in the aromatic ring. The distance between these energy fields is quantized and therefore can only take specific energies of light(wavelengths). This energy is then used to reduce NADP+ to NADPH. This reducing equivalent can then be used to reduce several molecules of CO2 which can be combined to form glucose. This results in the fact that if you deprive plants of specific wavelengths of light they will die.

Does ATP formation happen in the stroma or thylakoid space?

ATP formation happens in the stroma of the chloroplast during the light-independent reactions of photosynthesis, specifically in the process of ATP synthesis through the enzyme ATP synthase. In the thylakoid space, ATP is mainly produced during the light-dependent reactions of photosynthesis through the process of photophosphorylation.

How do the reactants of photosynthesis differ from the reactants of chemosynthesis?

Both photosynthesis and chemosynthesis are processes by which organisms produce food. The difference between the two are the energies it use. Photosynthesis makes use of solar energy, while chemosynthesis makes use of chemical energy.

What are 3 adaptations of leaves for photosynthesis?

1 leaves have larger surface area so they can absorb light from sun

2 they are thin so light can pass into them easily

3 the cells of leaves have chloroplast which absorb light energy

In what part of the plants does photosynthesis occurs in?

Photosynthesis occurs mainly in the chloroplasts of plant cells. More specifically, the chlorophyll pigments within the chloroplasts are responsible for capturing light energy and converting it into chemical energy through the process of photosynthesis.

In what cells do photosynthesis occur?

Sometimes, every cell in a plant is capable of photosynthesis. The important part of photosynthesis is the organelle chloroplast, which has the pigments that absorb the energy, as well as the enzymes that help produce the sugars.

Which letter identifies the structure that captures sunlight energy for photosynthesis?

The letter "C" typically identifies the structure that captures sunlight energy for photosynthesis, which is the chloroplast. This organelle contains chlorophyll, a pigment that absorbs light energy used in the photosynthetic process.

List the ingredients and products of photosynthesis?

The overall reactants (ingredients) are carbon dioxide and water.

The overall products are glucose and oxygen.

What gas used up in photosynthesis?

Carbon dioxide is used up in photosynthesis to produce glucose and oxygen. The process takes place in the chloroplasts of plant cells, where carbon dioxide is taken in from the atmosphere and converted into carbohydrates with the help of sunlight and water.

What are the factors affect photosynthesis?

Factors that affect photosynthesis include light intensity, carbon dioxide concentration, temperature, water availability, and the presence of chlorophyll. These factors can either enhance or limit the rate of photosynthesis in plants.

What provides the energy for photosynthesis to occur?

Photosynthesis occurs using sunlight as the primary source of energy. Sunlight is absorbed by chlorophyll in plant cells, which triggers a series of chemical reactions that convert carbon dioxide and water into glucose and oxygen.

What is the energy fixing stage of photosynthesis?

The energy-fixing stage of photosynthesis is the light-dependent reactions, which take place in the thylakoid membranes of chloroplasts. In this stage, light energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH.

What organelle are associated with plant photosynthesis?

Chloroplasts are the organelles associated with plant photosynthesis. They contain chlorophyll, the pigment that captures light energy to drive the process of photosynthesis, converting light energy into chemical energy in the form of glucose.

What is the organic compound produced during photosynthesis?

There three molecules produced by photosynthesis. These molecules are oxygen gas, adenosine triphosphate, or ATP, and nicotinamide adenine dinucleotide phosphate, or NADPH.

Why Plants need the sun for photosynthesis because?

Plants need the sun for photosynthesis because sunlight provides the energy needed to convert carbon dioxide and water into glucose, which is their main source of food. This process is carried out in chloroplasts, where sunlight is absorbed by chlorophyll, a pigment that initiates the chemical reactions of photosynthesis. Without sunlight, plants would not be able to produce their own food and ultimately would not survive.

What is the role of chlorophyll during the process of photosynthesis?

The chlorophyll in plants captures the light molecules which well later be used to make NADPH and ATP

there are photosynthetic proteins in the thylakoid membrane that absorb light which excites electrons to the next energy level which is used to recharge adp to get ATP and nadp+ to get nadph+h

How many molecules of high-energy sugars are produced as a result of one Calvin cycle?

Three molecules of high-energy sugars (G3P) are produced as a result of one Calvin cycle, which is a process in photosynthesis that converts carbon dioxide into sugars. These sugars are important in providing energy for the plant and serving as building blocks for other molecules.

Explain how oxygen is generated in photosynthesis?

During photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose and oxygen. The oxygen is a byproduct of the photosynthesis process. It is released into the atmosphere as a waste product.

Electron carrier that provides the high energy electrons needed to make carbon-hydrogen bonds in the third stage of photosynthesis?

NADPH (nicotinamide adenine dinucleotide phosphate) is the electron carrier that provides the high-energy electrons required to make carbon-hydrogen bonds in the third stage of photosynthesis (Calvin cycle). These electrons are essential for reducing carbon dioxide to produce sugars and other organic compounds. NADPH is produced during the light-dependent reactions of photosynthesis.

What reactions of photosynthesis take place in the stroma?

The Calvin Cycle, also known as the light-independent reactions of photosynthesis, takes place in the stroma of the chloroplast. This cycle involves the conversion of carbon dioxide into glucose using energy from ATP and NADPH produced during the light-dependent reactions.

What sequence accurately reflects the flow of electrons in photosynthesis?

In photosynthesis, electrons flow from water molecules to photosystem II, then to photosystem I, and finally to NADP+ ultimately producing NADPH. Along the way, the electrons generate a proton gradient that drives ATP production.

What molecule from the air is broken down from the Calvin cycle?

Carbon dioxide is the molecule from the air that is broken down during the Calvin cycle in photosynthesis to produce glucose.

What cell organelle is responsible for carrying out the function of the photosynthesis?

Chloroplasts are the cell organelles responsible for carrying out the function of photosynthesis in plant cells. These organelles contain chlorophyll, a pigment that captures light energy and converts it into chemical energy through a series of biochemical reactions.

What organisms use light to make food?

Organisms such as plants, algae, and certain bacteria use light to make their own food through the process of photosynthesis. They contain pigments like chlorophyll that absorb light energy and convert it into chemical energy to produce sugars and other organic compounds.

What happens to water in the light-dependent reactions?

Water is broken apart to release oxygen (O2), which is a product of photosynthesis, and two hydrogen ions.

The electrons are taken from the hydrogens to form hydrogen ions (H+). The electrons replace those lost in the chlorophyll when it absorbed a photon of light and was sent to transfer the high energy to make ATP.
