What starts light reaction in photosynthesis?
The light reaction in photosynthesis is initiated by the absorption of light by chlorophyll molecules in the thylakoid membranes of chloroplasts. This light energy is then used to split water molecules into oxygen, protons, and electrons, which kickstarts the process of energy production in the form of ATP and NADPH.
What is the production of ATP in photosynthesis called?
Glycolysis produces ATP in plants to power cellular processes. Photosynthesis harnesses the energy from the sun and stores it in glucose molecules.
What molecules in chloroplasts can absorb light?
Chlorophyll a and chlorophyll b are the main molecules in chloroplasts that can absorb light for photosynthesis. These pigments absorb light energy and convert it into chemical energy, which is used to drive the process of photosynthesis.
What do you call the clusters of chlorophyll molecules that capture light energy?
They are called photosystems. Photosystems are groups of chlorophyll molecules and associated proteins that work together to absorb and transfer light energy during the process of photosynthesis.
What are the plant cell molecules that absorb light energy called?
Chlorophyll.
Molecules that collect light energy are called p?
pigments .
How does water absorb light?
Water absorbs light through a process called absorption, where the molecules in water absorb the energy from light waves. This absorption causes the water molecules to vibrate and increase in temperature. The absorbed light energy is then converted into heat energy.
When light is absorbed light energy is transformed into stored energy true or false?
True. When light is absorbed by a substance, the light energy is converted into stored energy within the molecules of the substance. This stored energy can then be used for various processes such as chemical reactions or heat production.

What is production of heat energy by burning fuels?
The production of heat energy by burning fuels is a chemical reaction called combustion. During combustion, the bonds in the fuel molecules break, releasing energy in the form of heat and light. This process is commonly used in engines, furnaces, and power plants to generate heat and electricity.
What do you call the clusters of chlorophyll molecules that capture light energy?
They are called photosystems. Photosystems are groups of chlorophyll molecules and associated proteins that work together to absorb and transfer light energy during the process of photosynthesis.
Why is the production of light by a fluorescent light exothermic?
The production of light by a fluorescent light is exothermic because it involves the conversion of electrical energy into light energy with the release of heat as a byproduct. This process occurs when electric current passes through the gas inside the fluorescent tube, causing the gas molecules to become excited and emit photons of light.
How does light energy transform into heat energy?
When light energy is absorbed by an object, it causes the object's molecules to vibrate and move faster, which generates heat energy. This transformation occurs through a process called conversion of light energy into thermal energy.
What are the plant cell molecules that absorb light energy called?
Chlorophyll.
Where do electrons come from and how it gains energy during the light reaction?
They come from Photosystem ll. Photosystem ll gets them by ripping the electrons off of water by a process called photolysis. Electrons gain energy first in Photosystem ll, then later in photosystem l, through the absorption of energy from light.
