Why are light reactions required for the photosynthetic process?
Chloroplasts convert light energy into chemical energy. The energy of light captured by pigment molecules, called chlorophylls, in chloroplasts is used to generate high-energy electrons with great reducing potential.
The energy from photons hitting photo system II is used to produce what?
ATP
The energy from photons hitting photosystem 2 is used to produce what?
ATP
How is nuclear energy turned into light energy?
The most direct way for nuclear energy to be converted to light energy is via the process of gamma decay -- that is, when a nucleus decays and releases photons. The photons are not technically light -- being gamma rays, they have frequencies too high for human eyes to detect; however, the process of redshifting (which is when wavelength is stretched out either by universal expansion or, more commonly, objects moving away from the light) can, in theory and under extreme circumstances, make any wavelength visible. In practice, however, nuclear energy is converted into light the same way that all energy used is converted into light. Nuclear energy, like coal energy, can be used to heat water, which turns into steam, which spins a turbine, which induces a current, which eventually passes through the tungsten filament of a lightbulb, heating it to incandescence.
What device changes radiant energy in electrical energy?
Solar panels change radiant energy into electrical energy. Solar panels contain photovoltaic cells which are comprised of semiconductors which require little energy to emit electrons. The radiant energy contains well.. energy! This energy is stored in the photons, the ''packs'' light or other radiant energy comes in. This photons come in contact with the photovoltaic cells (which would appear as sheets of metal) passes on energy and this added amount of energy causes the material (photovoltaic cells) to emit electrons. The electrons (negative charge) are attracted to a positively charged metal (relative to the incident metal which the photons strike) and are then carried where needed (either stored or used).
What molecule found in the chloroplasts of plant cell traps photons of light?
The chlorophyll absorbs the light from the sun and transfers them to chlorophyll pair. This is the energy that is used to start food production.
What gets energy from the sun and makes its own food through photosynthesis?
Chlorophyll pigments are used. Photosynthetic organisms use this process
What energy is absorbed by palisade cell?
This is energy from sunlight, that is photons of electromagnetic energy.Palisade cells are a type of leaf tissues and can be found within the mesophyll in leaves of dicotyledonous plants. They contain chloroplasts, which convert the energy stored in photons to chemical energy through photosynthesis.
Why are light reactions required for the photosynthetic process?
Chloroplasts convert light energy into chemical energy. The energy of light captured by pigment molecules, called chlorophylls, in chloroplasts is used to generate high-energy electrons with great reducing potential.
What is the process by which the sun's energy is trapped as the source of eneregy used by virtually all living organisims?
Photosynthesis is a complicated process in which light energy is used to stimulate the combination of oxygen, carbon, and hydrogen into simple sugars which are then converted by cellular respiration (another complicated process) to energy in photosynthetic organisms (plants, mostly).

What happens to energy from the sun during photosynthesis?
Photons from the sun excite electrons in the photosynthetic pigments, leading to the production or either ATP or NADPH, with ATP storing the energy from the sun in the form of a high-energy pyrophosphate bond and NADPH storing the energy in the form of high-energy electrons. ATP and NADPH are then used to produce glucose, which is a relatively more permanent storage of energy.
What does chlorophyll do in chloroplast?
Chlorophyll is a green pigment which traps solar energy and starts the process of photosynthesis.
Light excites in photosynthetic pigments?
Light excites two sets of photosynthetic pigments. These are photosystem 1 (PS1) and photosystem 2 (PS2). PS1 is excited by photons at about 700 nanometers, while PS2 is excited at about 680 nanometers.
The energy from photons hitting photo system II is used to produce what?
ATP
How does sun energy work as an energy provides for plants?
It radiates electromagnetic energy, photons, which plans harness to perform a process called photosynthesis. The photon is used to split the 2 hydrogen atoms from H2O (water), of which one is stored while the other is used for energy to grow. The oxygen atom is released as waste product.
What is biosynthetic machinery?
Photosynthetic machinery transforms light energy into other forms so that it can be used for millions of years. It is similar to the process of photosynthesis that plants use.
The energy from photons hitting photosystem 2 is used to produce what?
ATP
