Oxygen and Oxidation

Photosynthesis occurs each time the sun’s light reaches the lives of a plant. The chemical ingrediants for photosynthesis are carbon dioxide (CO2), a gas that passes from the air into a plant via tiny pores, and water (H20), which absorbed from the soil by the plant’s roots. Inside leaf cells, tiny structures called chloroplasts use light energy to rearrange the atoms of the ingrediants to produce sugars, most importantly glucose (C6H12O6) and other organic molecules. Chlorophyll gives the plant its green color (Simon, 02/2012, pp. 92-93). Chemical reactions transfers the sun’s light energy into the chemical bonds that hold energy-carrying molecules. The most common are

Photosynthesis is the process in which plants consumed inorganic materials like solar light, carbon dioxide and water and converted it to an organic molecule like sugar and an inorganic gas like oxygen. Light is one of the major elements influencing the rate of photosynthesis; direct light concentration affects the noncyclic pathway (light

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms ' activities. Plants need photosynthesis to survive. The balanced chemical equation for photosynthesis is 6 CO2 + 6 H2O ? C6H12O6 + 6 O2. In English terms, this equation translates to six carbon dioxide plus six

The process of photosynthesis, by which light energy is used to convert inorganic compounds into organic substances with the release of oxygen, may be the most important biological event sustaining life (Keir et al. 2017). In the light-dependent reactions, the chloroplasts of a plant use the pigment chlorophyll to convert light energy into chemical energy. This energy is used to split water and produce oxygen (Eller et al. 2015). The energy is later used in the light independent reactions, where carbon dioxide (CO2) undergoes carbon fixation with the aid of enzyme rubisco, because it catalyses both carboxylation and oxygenation reactions and most of responses of photosynthesis to light, CO2, and temperature (John Evans 2013).

In light reactions, light is absorbed by chlorophyll in the thylakoid membrane and energizes the electrons. ATP is created from ADP and P. NADP accepts electrons and turns in to NADPH, which is energy. Once the light reactions have taken place, the light-independent, or ‘dark’ reaction occurs in the stroma, where CO2 is converted to sugar. The

A. A number of organisms in the nonexistence of oxygen from time to time go through a course of action described as fermentation. Fermentation permits these organisms to create energy under anaerobic conditions according to (www.sci.uidaho.edu. 2008).

Photosynthesis occurs in all green plants and is the beginning of nearly all food chains therefore a source of life to all living organisms. It is the process where plants transform light energy from the sun into chemical energy. By using light energy trapped by chlorophyll (light absorbing pigment), plants combine carbon dioxide and water to form glucose and oxygen.

In well 3A there was a chemical reaction between the sodium phosphate and copper sulfate. There was a light blue precipitate formation which proves there was a chemical reaction.

Redox reactions interact with and contribute to the achievement of each of these goals. For instance, the first goal is to break down the glucose into six carbon dioxide molecules. One of the stages in which this goal is accomplished is in pyruvate oxidation, which begins with a redox reaction. NAD+ is reduced to NADH by taking an electron from pyruvate, which becomes oxidized; hence the term “pyruvate oxidation”. Pyruvate can then split, releasing carbon dioxide.

Oxidation can be defined as a gain in oxygen or loss of hydrogen, loss in electrons, and therefore loss of potential energy. Reduction is gain of hydrogen, or gain in electrons, and gain of potential energy. The organic food molecules are OXIDIZED to CO2. This is the process of glycolysis and making energy. The carbon molecules gain oxygen and are oxidized, and release all that energy to generate ATP. NADH is the REDUCED from of NAD+, because of the gain in hydrogen, or gain in electrons.

Photosynthesis is essential to all living organism such as animals and plants. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reaction that converts carbon dioxide and water into oxygen, carbohydrates and water. (Textbook: Principles of Biology). The reactants and the products of photosynthesis are:

     To metabolic pathways involved in photosynthesis are light reaction and dark reaction. The first stage of the photosynthetic system is the light-dependent reaction, which converts solar energy into chemical energy. Light absorbed by chlorophyll or other photosynthetic pigments is used to drive a transfer of electrons and hydrogen from water to and acceptor called NADP , reducing it to the form of NADPH by adding a pair of electrons and a single proton. The water or some other donor molecule is split in the process. The light reaction also generates ADP, a process called photophosphorylation. ATP is a versatile source of chemical energy used in most biological processes. The light reaction produces no carbohydrates such as sugars.

Photosynthesis is a very complicated process. It is not as simple as plants need a little sunlight, water, and carbon dioxide, and viola oxygen is produced. There are many steps and processes that occur during photosynthesis which make it very complicated. Now the actual word photosynthesis in Greek means photo- “light”, and –synthesis “putting together”. This is the overall basic foundation that photosynthesis stands behind. Photosynthesis can only happen in plants and some algae, due to them having an organelle called chloroplast. Chloroplast has a pigment, which is called chlorophyll. Chlorophyll is a light absorbing pigment, which allows the plant to control solar energy and use it to distribute energy and food for the plant itself. Chloroplasts are usually located in the green tissue in the interior of the leaf called the mesophyll. A usual cell has around thirty to forty chloroplast. In the inner compartment there is a thick fluid called the stroma, with a system of interconnected membranous
