What uses energy from the high-energy electrons to transport hydrogen across the thylakoid membrane?

The protein complex ATP synthase uses the energy from high-energy electrons to transport hydrogen ions across the thylakoid membrane during the process of photosynthesis. This creates a proton gradient that drives the production of ATP, which is an important energy carrier in the cell.

The carbon to produce carbohydrates in the second stage of photosynthesis comes from?

The carbon to produce carbohydrates in the second stage of photosynthesis comes from carbon dioxide in the atmosphere. During the Calvin cycle, carbon dioxide is fixed and converted into glucose molecules that make up carbohydrates.

What is the chemical responsible for photosynthesis?

Chlorophyll is the primary pigment responsible for capturing sunlight during photosynthesis in plants. It is located in the chloroplasts of plant cells and absorbs light energy to drive the process of converting carbon dioxide and water into glucose and oxygen.

What chemical is responsible for photosynthesis?

Chlorophyll is the primary pigment responsible for photosynthesis in plants. It absorbs light energy and converts it into chemical energy that the plant can use to create sugars from carbon dioxide and water.

The place where light reactions occur in a plant?

it occurs in the chloroplast / stroma

oh and light reactions can only occur in a plant and some protists because only plants and some protists can perform photosynthesis, and it is in this process which light reactions occur. other cells don't have chloroplast and stromas.

Why carbon dioxide is important for photosynthesis?

It's important to all life. Starting with plants there is a chain.

Plants fix carbon dioxide into starches and sugars during photosynthesis. They use the energy of light to make CO2 and water into sugars.

We animals need them to do that so that we can have food and get energy. We digest the sugars and starches produced by plants, in our gut, and that feeds our cells.

What is made as a result of photosynthesis?

The primary byproduct of photosynthesis is glucose, a simple sugar that plants use as a source of energy. Oxygen is also produced as a waste product during photosynthesis, which is released into the atmosphere.

Are thylakoids organelles?

Thylakoids are not organelles themselves, but rather a membrane-bound structure found within chloroplasts. They are where the light-dependent reactions of photosynthesis take place, specifically the process of converting light energy into chemical energy.

When does the plant use oxygen at night or when the shade is down?

Plants photosynthesize during the day using sunlight to produce oxygen and glucose. At night or when sunlight is not available, plants typically respire, using oxygen and glucose to produce energy. However, this process consumes more oxygen than it produces and releases carbon dioxide.

What is the difference between chlorophyll and photosynthesis?

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar.

The Calvin cycle is the set of chemical reactions that take place in chloroplasts during photosynthesis. The cycle is light-independent because it takes place after the energy has been captured from sunlight.

What contains pigments needed for photosynthesis?

Chloroplasts contain pigments needed for photosynthesis, including chlorophyll a, chlorophyll b, carotenoids, and xanthophylls. These pigments capture light energy and convert it into chemical energy during the process of photosynthesis.

How does photosynthesis in plants affect the carbon cycle?

During photosynthesis, plants take in carbon dioxide from the atmosphere and convert it into glucose through the process of photosynthesis. This helps to remove carbon dioxide from the atmosphere, reducing the overall levels of CO2 and thereby mitigating the greenhouse effect and global warming. Additionally, plants release oxygen as a byproduct of photosynthesis, which is essential for the respiration of animals and other organisms.

Does the dark reactions of photosynthesis release oxygen?

Molecular oxygen is formed in the light dependent reaction of photosynthesis. This occurs in the electron transport chain in the protein complexes of the thylakoid membrane. The water splitting complex yields oxygen, hydrogen ions and electrons.

Which organisms are responsible for the majority of the net primary productivity in shallow marine waters?

Phytoplankton, particularly diatoms and dinoflagellates, are responsible for the majority of net primary productivity in shallow marine waters. These microscopic organisms play a key role in the marine food web, converting sunlight into organic matter through photosynthesis.

Which structure regulates gas exchange during the processes of photosynthesis and respiration?

In plants, the stomata regulate gas exchange during the processes of photosynthesis and respiration. Stomata are small pores located on the surface of leaves that open and close to control the movement of gases such as carbon dioxide and oxygen. By regulating the opening and closing of stomata, plants can optimize gas exchange for efficient photosynthesis and respiration.

Is light common to both cellular respiration and the light reactions of photosynthesis?

Yes, light is common to both cellular respiration and the light reactions of photosynthesis. In photosynthesis, light energy is used to convert water and carbon dioxide into glucose and oxygen. In cellular respiration, the energy stored in glucose is released through a series of reactions to produce ATP, and light is not directly involved in this process.

Where does the ATP and NADPH in the Calvin cycle come from?

ATP is produced through the process of cellular respiration in the mitochondria of plant cells. NADPH is generated during the light reactions of photosynthesis in the chloroplasts. Both ATP and NADPH are used as energy sources for the Calvin cycle to run the biochemical reactions that convert carbon dioxide into glucose.

What part does photosynthesis play in a nitrogen cycle?

In the process of photosynthesis, plants need the sun's energy, water to make food for themselves in the form of ATP ( adenosine triphosphate ) , which is packages of energy. Carbon coming into the plants ( or algae ) along with water make those ATP into a bigger molecule, which is know as glucose.

Formula: 6 CO2 + 6 H2O + Suns Energy -> glucose + oxygen

Photosynthesis has an affect on the carbon cycle because it reduces the amount of CO2 in the air and redirects it into sugars which feeds animals as well as humans.

How does a carbon atom travel through photosynthesis?

During photosynthesis, carbon atoms are taken up by plants in the form of carbon dioxide from the atmosphere. These carbon atoms are then incorporated into organic molecules like sugars through a series of chemical reactions in the chloroplasts of plant cells. The carbon atoms ultimately end up as part of glucose molecules, which can be used as an energy source by the plant or stored for later use.

What is a good thesis statement about photosynthesis?

Photosynthesis is a crucial biological process that converts sunlight into chemical energy, providing oxygen as a byproduct. A strong thesis statement could be: "Photosynthesis is a fundamental process in the cycle of life, serving as the primary mechanism through which plants and other autotrophs convert solar energy into usable energy for growth and survival."

Why chlorophyll is needed for photosynthesis?

Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesis carbohydrates from CO2 and water. This process is known as photosynthesis and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants, photosynthesis can be said to be the source of our life also. The energy plants have from water and light is converted from light energy to chemical bond energy

How much Oxygen is produced by average plant per day?

On average, a plant can produce around 5-10 grams of oxygen per day through photosynthesis. This amount can vary depending on factors like the plant species, size, growth conditions, and sunlight availability.

Why is photosynthesis referred as a biochemical pathway?

Photosynthesis is referred to as a biochemical pathway because it is a series of chemical reactions that take place in living organisms involving multiple enzymes and molecules to convert sunlight, water, and carbon dioxide into glucose and oxygen. It is a complex process that involves various biochemical reactions within the cells of plants and other photosynthetic organisms.

Why is photosynthesis important for your survival?

It is how carbon dioxide is converted into oxygen on this planet. Without it, earth would be much like Venus.

carbon dioxide + water + light energy → glucose + oxygen + water Photosynthesis is important because that is what produces oxygen! And oxygen is the same thing as air! WE NEED AIR!
