Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen.

Light energy is converted to chemical energy during the first stage of photosynthesis, which involves a series of chemical reactions known as the light-dependent reactions. ... These molecules store energy for use in the next stage of photosynthesis: the Calvin cycle.

Photosynthesis is the process by which plants and some bacteria and protists synthesize sugar molecules from carbon dioxide, water, and sunlight. ... During the light reactions, an electron is stripped from a water molecule freeing the oxygen and hydrogen atoms.

Photosynthesis. Photosynthesis is the process by which green plants use sunlight energy to make their own food. It takes place inside the chloroplasts of plant cells.

Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen. Many reactions occur, but the overall chemical reaction for photosynthesis is: 6 CO2 + 6 H2O + light → C6H12O6 + 6 O. Carbon Dioxide + Water + Light yields Glucose + Oxygen.

Examples of photochemical reactions Photosynthesis: plants use solar energy to convert carbon dioxide and water into glucose and oxygen. Human formation of vitamin D by exposure to sunlight. ... Vision is initiated by a photochemical reaction of rhodopsin.

Pigments absorb light used in photosynthesis. In photosynthesis, the sun's energy is converted to chemical energy by photosynthetic organisms. However, the various wavelengths in sunlight are not all used equally in photosynthesis. ... As a note, chlorophyll a absorbs slightly different wavelengths than chlorophyll b.

The net effect of these steps is to convert light energy into chemical energy in the form of ATP and NADPH. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle.

The chlorophyll present in leaves absorb light energy from the sun and convert into chemical energy. Glucose is the simple food which is prepared first in the process of photosynthesis. Glucose and oxygen are the final products of photosynthesis.

Most autotrophs use water as the reducing agent, but some can use other hydrogen compounds such as hydrogen sulfide. Some autotrophs, such as green plants and algae, are phototrophs, meaning that they convert electromagnetic energy from sunlight into chemical energy in the form of glucose.

The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process.

Photosynthesis and chemosynthesis are both processes by which organisms produce food; photosynthesis is powered by sunlight while chemosynthesis runs on chemical energy. The majority of life on the planet is based in a food chain which revolves around sunlight, as plants make food via photosynthesis.

Beginning with the absorption of light by chlorophyll, the light reactions convert light energy into chemical energy in the form of ATP and NADPH. The ATP provides the energy, and the NADPH supplies the electrons for the Calvin cycle, which converts carbon dioxide to sugar.

The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy.

Photosynthesis is the process of converting light energy into chemical energy in the form of glucose, in small structures called chloroplasts. ... In cellular respiration, the energy stored in the bonds of the glucose molecule is broken down and transformed to another type of energy, ATP.

They collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria.
