There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. Oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria. During oxygenic photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2), which produces carbohydrates. In this transfer, the CO2 is "reduced," or receives electrons, and the water becomes "oxidized," or loses electrons. Ultimately, oxygen is produced, than released, along with carbohydrates used for food.
Aerobic cellular respiration and oxygenic photosynthesis are the main pathways of energy flowing in living things. Photosynthesis is known as a process that is used by plants, algae and bacteria get energy from sunlight into chemical energy. Aerobic cellular respiration makes ATP, finalizes e- acceptor is oxygen. Aerobic cellular respiration involves the products of photosynthesis, which are glucose and oxygen, while photosynthesis uses the products in aerobic cellular, which are carbon dioxide and water. These reactions are how cells make and store energy.
Introduction: Photosynthesis is a process used by plants and specific types of bacteria in order to make their own food source from sunlight to chemical energy. It is mainly occurred within the leaves of the plant. The reaction requires light energy in order for it to be absorbed by chlorophyll. During the reaction carbon dioxide, water is converted into glucose and oxygen as shown below: Figure 1 (photosynthesis uses light energy to convert carbon dioxide into a carbohydrate) (The Chemical Equation of Photosynthesis. 2018, Accessed 16 March 2018) There are two types of photosynthetic processes; one includes oxygenic photosynthesis, which is most common and demonstrated through plants, algae and cyanobacteria while the other one is an-oxygenic photosynthesis.
In the Oxidative fermentation tube the media was a differential media that helps determine whether specific bacteria can oxidize or ferment to metabolize glucose. Citrate test checks to see which bacteria could citrate as the only source of carbon. A positive test shows that an alkaline environment ia created and that the pH level rose. The color of the media changed from green to blue if its positive. The Bile Esculin agar test has its medium as selective and differential.
Step four is basically just where water can now enter and bind to the active site through hydrogen bonding, which is between the hydrogen atoms of water and the Histidine-57 nitrogen. The fifth step is the step where the water and oxygen make a nucleophilic attack on the carbonyl carbon of the acyl-enzyme intermediate. This pushes the carbonyl’s electrons onto the carbonyl carbon, while the Histidine-57 takes one proton from the
Just like respiration, photosynthesis has two phases but they do different things. The first phase is the Light Phase where chlorophyll absorbs red, blue, violet light (energy) to produce ATP for the dark phase and to split H20 into hydrogen and oxygen. The light phase can only occur when light is present. The second phase is the Dark Phase also known as the Calvin Cycle. In this phase it uses the ATP produced from the light phase to join atmospheric CO2 (Carbon Dioxide) to the H2 (Hydrogen) to make C6H12O6
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy in the form of NADPH and ATP. The light-dependent reactions take place in the thylakoid membranes in the granum, in the chloroplast. In the light-independent reactions or Calvin Cycle, the energized electrons from the light-dependent reactions provide energy to assemble carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin Cycle because carbons are constructed into carbohydrate molecules in a cycle of chemical processes. Even though the light-independent reactions do not use light as a reactant, they require the products of the light-dependent reactions to function.
When carbon dioxide reacts with water, carbonic acid is made. This 0.1% aqueous bromothymol blue solution (also known as Bromthymol Blue) is a commonly used pH indicator. Bromthymol blue changes color over a pH range from 6.0 (yellow) to 7.6 (blue). It is a good indicator of dissolved carbon dioxide (CO2) and other weakly acidic solutions. Despite its name, bromothymol blue solution may sometimes appear yellow or reddish depending on the pH of the stock water used to prepare this pH indicator solution.Low levels of carbon dioxide or acid in solution with bromothymol blue indicator will appear blue.
As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water. Each stage of cellular respiration is important because That cellular respiration is the process by which cells produce adenosine triphosphate, or ATP. ATP is the molecule that carries energy for cells of a living organism, and it is regarded as a "currency" of the cells in the organism.
Introduction Photosynthesis is the process whereby chlorophyll containing cells in green plants convert incident light to chemical energy and synthesise organic compounds from inorganic compounds (Great Illustrated Dictionary, 1984). It could also be presented by this equation (6CO2 + 6H2O C6H12O6 + 6O2), all in the presence of sunlight (Mader, 2010). The word photosynthesis means “putting together with light” (Ashley, 2000). In order for plants to photosynthesis, a source of light energy is needed. This energy is normally obtained from the sun.
