Why is photosynthesis considered an energy conversion reaction?
Photosynthesis converts light energy from the sun into chemical energy stored in glucose molecules. This process involves the conversion of light energy into chemical energy, making it an energy conversion reaction.
What is an energy conversion that involves chemical energy?
The conversion of chemical energy into thermal energy through combustion is a common example. Burning wood or gasoline releases the stored chemical energy in the form of heat and light energy.
Why when the colour is bright the reaction get faster?
Bright colors can absorb more light energy, leading to increased activation of molecules in a chemical reaction. This higher energy input can accelerate the reaction rate by providing the necessary activation energy for the reaction to occur. Bright colors may also increase the efficiency of light absorption and conversion to chemical energy, boosting the reaction rate.
What is the layer that absorbs excess light?
The layer that absorbs excess light in photosynthesis is the photosystem. It consists of pigments like chlorophyll that capture light energy and transfer it to the reaction center for conversion into chemical energy.
Why must the light reaction occur before the dark reaction?
The light reaction produces ATP and NADPH, which are needed to fuel the dark reaction. The dark reaction (Calvin Cycle) uses the ATP and NADPH produced in the light reaction to fuel the conversion of carbon dioxide into glucose. In essence, the light reaction provides the energy source that drives the dark reaction.

What type of energy conversion is going on in a glow stick?
In a glow stick, chemical energy is converted into light energy through a chemical reaction. When the chemicals inside the glow stick mix together, they undergo a reaction that releases energy in the form of light.
What is the energy conversion in Burning of a matchstick?
The energy conversion that occurs in the burning of a matchstick is chemical energy being converted into heat and light energy. When the matchstick is ignited, the stored chemical energy in the match head is released through a chemical reaction, producing heat and light as byproducts.

What is the energy conversion of a firecracker?
A firecracker converts chemical energy stored in its gunpowder into thermal and light energy when ignited. The combustion reaction in the gunpowder produces heat and light, resulting in the explosive effect of a firecracker.

What a pigment molecule that transfers electrons during light reaction?
The pigment molecule that transfers electrons during the light reaction is chlorophyll. Chlorophyll absorbs light energy and transfers electrons to the reaction center of the photosystem, initiating the flow of electrons through the electron transport chain. This process is essential for the conversion of light energy into chemical energy during photosynthesis.
How is ATP produced during the light reaction in photosynthesis?
During the light reaction of photosynthesis, ATP is produced through a process called photophosphorylation. This process involves the conversion of light energy into chemical energy, which is used to add a phosphate group to ADP, forming ATP. This ATP is then used as an energy source for the dark reaction of photosynthesis, where carbon dioxide is converted into glucose.
What is the function of the light independent reaction of photosynthesis?
To provide ATP and NADPH to drive the next part of photosynthesis, the Calvin Cycle (AKA Dark Reaction, Light Independent Reaction). Light reactions also produce oxygen gas as a byproduct.
What is an energy conversion of a candle burning?
When a candle burns, the chemical energy stored in the wax is converted into heat and light energy through a combustion reaction. The wax is oxidized (burned) by oxygen in the air, releasing energy in the form of heat and light.
