Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Chlorophyll-a is the pigment that works on converting light energy into the energy of chemicals. It is also called the primary photosynthetic pigment because it performs the first reaction of photosynthesis which involves the conversion of sunshine energy into energy.
The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules.
– The light reactions take place inside the thylakoids of chloroplasts. – The light reactions produce chemical energy in the form of NADPH and ATP.
ATP is produced on the stromal side of the thylakoid membrane, so it is released into the stroma. The electron arrives at photosystem I and joins the P700 special pair of chlorophylls in the reaction center.
In fact visible ‘light’ is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. It can also be described as a flow of particle-like ‘wave-packets’, called photons, that travel constantly at the speed of light (about 300 000 kilometres per second).
Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.Jun 9, 2021
The most basic source of chemical energy is coal. Coal is formed when excessive heat and pressure under the Earth surface act upon rocks for millions of years. Coal is burned to obtain chemical energy.
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. It is like a solar panel that changes sunlight energy into electric energy. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.
During photosynthesis, “producers” like green plants, algae and some bacteria convert light energy from the sun into chemical energy. Photosynthesis produces chemical energy in the form of glucose, a carbohydrate or sugar.
Light-dependent reaction takes place in the presence of light energy in thylakoid membranes (grana) of the chloroplast Calvin cycle occurs at the stroma of the chloroplast.
Explanation: Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.
The light reaction is also known as photolysis reaction and takes place in the presence of light. It usually takes place in the grana of chloroplasts.
So, the correct option is ‘Hill reaction‘.
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.
When light shines on chlorophyll, the light energy is transformed into? Chemical energy, in the form of glucose 2.
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.Feb 12, 2020
Explanation: Light travels in straight lines as a wave through the air. There is a small portion of the electromagnetic spectrum, which is comprised of visible light that we can see. … They use electricity or chemical energy that is transferred to light energy to generate visible light.
