Absorption Spectra Graph

Light intensity is a key component in photosynthesis, amongst carbon dioxide and water to sustain a suitable rate of photosynthesis. Chlorophyll absorbs the light, causing photoexcitation and the formation of NADPH and ATP with production of O2 as a by-product. The Calvin Cycle takes the NADPH and ATP to reduce CO2 into sugars (CH2O), and return NADP+ and ADP + Pi to the light reactions. The process will then repeat. (Reece, et al, 2015)

In photosynthesis, cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun, and then the cells release oxygen (O2) and store glucose (C6H12O6). The formula of photosynthesis is:

We measured the rate of photosynthesis in this lab. By exposing spinach leaves to light, we were triggering photosynthesis to start. Photons from the light excite electrons in the accessory pigments in the leaves which then causes them to eventually transfer their energy to the chlorophyll a molecule in the reaction center which causes an electron to jump to a primary electron acceptor, thus moving the energy along. When this electron jumps, the photolysis of water occurs in order fill the electron hole in the chlorophyll a molecules. H2O splits into electrons, H+ ions, and oxygen.

Photosynthesis is the chemical process of capturing light energy and converting it into a chemical form. Through a series of reactions, the process takes sunlight, carbon dioxide, and water to produce oxygen and a carbohydrate, usually a sugar called glucose. The oxygen is released into the atmosphere, while the glucose is stored inside the plant. Because sunlight is required, photosynthesis is a diurnal activity.

As sunlight is absorbed by the plants they stars the process of photosynthesis. When chlorophyll absorbs the light energy, an electron gains energy and it is excited. This excited electron is transferred to other molecule which is called primary electron acceptor. The chlorophyll molecule is oxidized and has a positive charge on it. This results in the splitting of water molecule and the transfer of energy to ATP (adenosine triphosphate) and reduce NADP (nicotinamide adenine dinucleotide phosphate).ATP is an energy source and NADP is an electron donor. They both plays important role in the photosynthesis process. Photosynthesis takes place in the leaves of plants

Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture light energy and utilize it to make energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use ATP and NADPH to capture and reduce CO2.

Plants utilize chloroplasts to perform photosynthesis to produce glucose. Photosynthesis consists of two stages called light reactions and the Calvin cycle. Within the chloroplast, the thylakoid is the site of light reactions. The thylakoid is capable of absorbing light energy and transforming it to chemical energy in the form of ATP and NADPH which will later be used in the Calvin cycle. Pigments located inside the thylakoid allows for the absorption of visible light (Campbell, pg. 191). There are three significant types of pigments in chloroplast: chlorophyll a (main light-absorbing pigment) , chlorophyll b (accessory pigment), and carotenoids (group of accessory pigments).

Photosynthesis is a reaction in which light energy is converted into glucose and ATP. The chemical equation for this reaction is CO2+H2O+light energy--->C6H12O6+O2. This reaction takes place in the chloroplast of a plant cell. There are two parts that make up photosynthesis: the light reactions that occur in the thylakoid membrane, and the Calvin cycle, which occurs in the stroma.

Photosynthesis, the basis of life as it produces oxygen that many organisms need, is often seen as the general equation CO2+H2O+lightC6H12O6+O2, yielding glucose and oxygen as products. However, when the process is further broken down, photosynthesis can be divided into two reactions: light-dependent and light-independent. In addition, because photosynthesis is an endergonic reaction, the process will be slow to happen due to the fact that the products have more energy than the reactants. Furthermore, before glucose and oxygen can be produced, the light-dependent reaction must occur first. In this reaction light strikes the chloroplast causing a series of reactions, such as water splitting, the production of ATP, and NADPH is produced as an end result. After this occurs, the light-independent reaction occurs, starting with ATP and NADPH to reduce carbon dioxide to sugar. Carbon dioxide is then broken and carbon enters the cycle to leave as sugar, while the ATP generates energy for the reaction and NADPH adds electrons to form the sugar. In the end, glucose is made after several turns of the Calvin cycle. Overall, both the cycles work together in order to form sugar and oxygen that is essential to many living

Light-independent reactions trap the energy from the sunlight to form NADPH to form ATP which gives off oxygen gas. The light-independent reactions use chemical energy and carbon dioxide to build long-term energy storage molecules like glucose and many other carbohydrates. The ATP and NADPH molecules produced in light-independent reactions convert CO2 (carbon dioxide) into carbohydrate molecules such as glucose and others. Carbohydrates are a better option for long-term storage than that of ATP or NADPH. CO2 molecules enter the Calvin cycle from the atmosphere. Enzymes in the liquid stroma of the chloroplast combine the CO2 molecules with other carbon-based molecules that have already been presented inside the organelle. This then forms three-carbon

Photosynthesis is the processes that captures energy from the sunlight to male sugars that store chemical energy. and cell respiration releases chemical energy from sugars and other carbon based molecules to make atp when oxygen is presented. and atp is the molecule that transfers energy from the breakdown of food molecules to cell processes. With all of these process they work together to capture energy by the sun and convert it into everyg of life. It starts with the photosynthesis. First, the carbon dioxide and oxygen will enter the leaves in plants through the stomata. then the water travels from the roots and will go into the vascular system. then chloroplast absorbs sunlight. However, there's 2 part in hopothesis. The parts re light dependant and light independent.

Photosynthesis is the single most important chemical process on the earth. The light reactions within the steps of photosynthesis convert solar energy to chemical energy. Water is split, providing a source of electrons and protons that give off oxygen as a by product, allowing light to be absorbed by chlorophyll (Urry, 2016). There are multiple major reactants necessary for photosynthesis:

Life on Earth is dependent entirely on the energy from the Sun, not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun, in the form of photons, is actively captured by chlorophyll and related pigments present in photosynthetic organisms, like plants and algae. This captured energy is used to convert carbon dioxide into complex energy-rich molecules that can be used by themselves

     Photosynthesis has a two-stage performance before plants produce the two products they are known to produce. These stages are Photosystem I and II. Photosystem II is dependant on light reactions for energy which causes the electrons to be react and be transferred to Photosystem II. The electrons are transported through the Photosystem II electron transport system, however some energy is used to drive ATP synthesis. Meanwhile, light is being absorbed by the Photosystem I, which causes the electrons to react. This process sends the electrons to the Photosystem I transport system where some energy is released as electrons travel through the electron transport system and is captured as NADPH. When this process is completed oxygen is released from the plant and glucose has been

In this project I believe the outcome will be that light energy is essential for photosynthesis to occur. The aim was to show that light is necessary for photosynthesis. Photosynthesis is the process of converting light energy into chemical potential energy and storing it as starch. This process occurs in plants and some algae. Plants need light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts,
