What happens during Photosynthesis? What does Photosynthesis produce? Why is photosynthesis important for humans? This putative reaction can be represented as: However, some folks have missed the purpose of photosynthesis. Our major sources of energy such as natural gas, coal and oil were made millions of years ago from the remains of dead plants and animals which we already know got their energy from photosynthesis.
An Introduction to Photosynthesis and Its Applications About the Author This article was written by the Sciencing team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information. Animals such as the zebra eat plants to obtain their needed energy and nutrients.
The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use.
This information can be written in a word equation as shown below. What have you learned so far? That photo receptor is in effect reset and is then able to repeat the absorption of another photon and the release of another photo-dissociated electron.
These reactions occur in two stages: This equation is merely a summary statement, for the process of photosynthesis actually involves numerous reactions catalyzed by enzymes organic catalysts. These pigments are embedded in plants and algae in complexes called antenna proteins.
The excited electrons lost from chlorophyll from photosystem I are supplied from the electron transport chain by plastocyanin.
The chlorophyll for photosynthesis is used to provide the energy required for the reaction to take place. The chloroplasts within the plant store the chlorophyll, and these are found in the mesophyll layer of the leaf.
While it is important that photosynthesis provides food and oxygen, its impact on our daily lives is far more extensive. This oxygen is what we breathe and we cannot live without it. This electron is passed to a modified form of chlorophyll called pheophytinwhich passes the electron Photosythesis important a quinone molecule, starting the flow of electrons down an electron transport chain that leads to the ultimate reduction of NADP to NADPH.
References Arizona State University: You already know that plants need carbon dioxide, water and sunlight to make their food. Sunlight is absorbed by a green chemical in the leaves. We directly or indirectly feed on photosynthetic products Why is photosynthesis important to your life and environment?
During these reactions light energy is converted to chemical energy. It is a series of complex biochemical reactions and occurs in higher plants, algae, some bacteria and some photoautotrophs.
What is needed for Photosynthesis? This is the reason that plants appear green to us. Some of the glucose is used to provide energy for the growth and development of plants while the rest is stored in leaves, roots or fruits for later use by plants.
It is this energy that is used to split water molecules into hydrogen and oxygen. That freed electron is transferred to the primary electron-acceptor molecule, pheophytin.
Hydrogen ions thus released create a chemical potential chemiosmotic across the membrane that finally results in synthesis of ATP. Carbon dioxide from the air passes through small pores holes in the leaves.
The thylakoid itself is enclosed by the thylakoid membrane, and within the enclosed volume is a lumen or thylakoid space.
These membranes facilitate the electron transport chain, where high energy electrons are used to create a proton gradient that drives ATP production. Most of the removed electrons and hydrogen ions ultimately are transferred to carbon dioxide CO2which is reduced to organic products. Plants that do not use PEP-carboxylase in carbon fixation are called C3 plants because the primary carboxylation reaction, catalyzed by RuBisCO, produces the three-carbon 3-phosphoglyceric acids directly in the Calvin-Benson cycle.

Would you like to merge this question into it?The important role of photosynthesis Photosynthesis is not just about oxygen production it is also about energy production. Posted on April 9, by Bill Cook, Michigan State University Extension.
Photosynthesis is important because it provides two main things: food; oxygen; Some of the glucose that plants produce during photosynthesis is stored in fruits and roots.
This is why we are able to eat carrots, potatoes, apples, water melons and all the others. These foods provide energy for humans and animals.
Photosynthesis and side products Wood is a very important material used not just as fuel but in many fields, including construction. Paper, cotton and other natural fibers, for instance, consist of cellulose produced almost entirely by photosynthesizing plants.
Even wool depends on the energy sheep obtain from grass, and photosynthesis.
Photosynthesis is the conversion of carbon dioxide and water into carbohydrates using energy from sunlight.
It is the main process by which new energy becomes available to life on Earth. Plants and algae use photosynthesis to convert light energy into a form available to other organisms, and thus form the base of almost every food chain. Photosynthesis consists of two distinct series of reactions called the light reactions and dark reactions.
In the light reactions through a process known as photophosphorylation, sunlight energizes an electron in chlorophyll which is then transported along a membrane to create a proton gradient.
Science in Society spoke with Para Gallio about the importance of photosynthesis, and the role it plays in her research.
On a basic level, what is photosynthesis? Photosynthesis is the process by which light energy from the sun is absorbed and converted into organic compounds.Download
