During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.
How is light energy converted to chemical energy during photosynthesis quizlet?
How is light energy converted into chemical energy during photosynthesis? Light energy absorbed by pigments produces high-energy electrons that are used to convert NADP+ and ADP to the compounds NADPH and ATP, trapping the energy in chemical form.
What is the process of converting light energy into chemical energy?
photosynthesis , the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
How is light energy converted to ATP during photosynthesis?
During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.
What type of energy is light?
Radiant energy includes visible light, x-rays, gamma rays, and radio waves. Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on earth possible.
What can light energy be transformed into?
Light energy can be converted to heat energy . Electrical energy can be converted to mechanical energy, light energy, heat energy, etc. Chemical energy can be converted to electrical energy. Thermal energy can be converted to heat energy.
What are 2 phases of photosynthesis?
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle
Do plants make all their ATP by photosynthesis?
Unlike animals, which make many ATP by aerobic respiration, plants make all of their ATP by photosynthesis .
What is the most abundant form of energy in a cell?
Eukaryotic cells use three major processes to transform the energy held in the chemical bonds of food molecules into more readily usable forms — often energy-rich carrier molecules. Adenosine 5′-triphosphate, or ATP , is the most abundant energy carrier molecule in cells.
What are 3 sources of light energy?
Natural sources of light include the sun, stars, fire, and electricity in storms . There are even some animals and plants that can create their own light, such as fireflies, jellyfish, and mushrooms.
What are three examples of light energy?
- Visible light.
- Infrared waves.
- X-rays.
- Ultraviolet light.
- Gamma rays.
- Radio waves.
- Microwaves.
What are the 2 types of light energy?
- Visible light: Only visible light can be seen through the naked eye. ...
- Infrared Light: It is also a type of electromagnetic energy which emits heat. ...
- X-rays and Ultraviolet light: These are short light waves used by doctors to take photographs inside our body to find out fractures on our bone.
What are 5 examples of energy transfer?
- A swinging pirate ship ride at a theme park. Kinetic energy is transferred into gravitational potential energy.
- A boat being accelerated by the force of the engine. The boat pushes through the water as chemical energy is transferred into kinetic energy.
- Bringing water to the boil in an electric kettle.
Where is light energy found?
Light energy is given off by things like stars, light bulbs, lasers, and hot objects. Our Sun – which is also a star – transmits light energy to Earth. The Sun is a natural source of light energy .
What household items use light energy?
There are many example we see in our routine life carrying light energy like lightened candle, flash light, fire, Electric bulb, kerosene lamp, stars and other luminous bodies etc. Each act as a source of light. Even a burning candle is an example for light energy.
Which step in photosynthesis does not need light?
The light-independent stage, also known as the Calvin Cycle , takes place in the stroma, the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light-independent reaction.
