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.
The electrons are then transferred to PSII. Photolysis provides energy in the form of electrons so that the PSII can continue to function which will later on lead to the production of NADPH. Also, photolysis provides protons which will later on lead to the production of ATP. Protons are produced through photolysis in PSII and the cytochrome complex. 2 protons are released into the thylakoid space through the splitting of a hydrogen molecule.
Because the entire structure of the mitochondria is optimized for the production of a proton gradient, a more accurate description of these organelles would be "the cell's batteries". Specifically, mitochondria are the site of aerobic respiration, where sugars and fatty acids are broken down in the presence of oxygen to produce energy in the form of ATP. Carbon dioxide is formed as a byproduct. As we shall see, far more ATP is generated by the mitochondria than by the cytosolic enzymes responsible for anaerobic glycolysis. Glycolysis, or anaerobic respiration, is the first phase of sugar breakdown at the cellular level.
This process is done through numerous reactions; an example is metabolic pathway. In cellular respiration, chemical energy that comes from fuel molecules is converted into ADP. ADP join with phosphate, then converts into ATP to form energy currency of cells. Cells release phosphate after consuming the ATP, which join with ADP to renew the cycle. The cycle state is called the glycolysis, electron transport and the acid cycle.
It usually takes place in the leaf and it is used by plants to create sugar from sunlight. Eukaryotic cells within the plant are able to do this type of process by capturing light energy from the sunlight through the use of pigments and converting it into chemical energy. Without the sunlight this process and its stages wouldn’t be able to function properly to create sugar due to it being a light-dependent reaction. Photosynthesis has to take place due to the fact that it helps eukaryotes survive. During this cellular process, oxygen is released in the form of waste in to the atmosphere which is what organisms have to breathe in order to
Figure4 - the chemical structure of sucrose. Figure5 - the chemical structure of lactose. Cellular respiration is when food molecules like glucose are oxidised to form carbon dioxide and water. Adenosine triphosphate is created by a catabolic pathway to be used by the cell. Cellular respiration happens in both eukaryotic and prokaryotic cells.
This experiment is set up the study the effect of different sodium bicarbonate concentrations on the rate of photosynthesis in spinach (Spinacia oleracea). Photosynthesis is the process by which plants and other photoautotrophs synthesize organic compounds from carbon dioxide (Faculty of Science and Horticulture, 2018). Photosynthesis takes place in the chloroplast of a plant cell, where sunlight, water, and carbon dioxide are used in a reaction to produce oxygen and sugar (Reese 2017). In the photosynthesis reaction carbon dioxide is reduced to make sugar and water is oxidized to make oxygen. In this experiment oxygen production is being used to measure the rate of photosynthesis.
Doriana Spurrell What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively? Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis. Background Information: Photosynthesis is the process in which plants use light energy to transform into chemical energy. The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die.
The process of cellular respiration, cells extract the energy stored in the glucose molecule (Campbell & Reece, 2005). The molecule is a sugar that provides major fuel for cellular to work. But the carbon skeleton works on the row material for synthesis of all different verities of small organic molecules. For example amino acids and fatty acids. Such sugar molecules that are not immediately used are incorporated into disaccharides and polysaccharides.
Biodiesel uses the same properties of diesel as fuel for cars. Biodiesel has many sources for it to be produced, these include soya, canola, jatropha, sunflower seed, etc. and animal fats (Khemani, 2011). Most of the used cooking oil thrown end up being collected to produce biodiesel; most restaurants donate their used cooking oil to prevent from throwing it in the drain. Rudolf Diesel who invented the diesel engine conducted an experiment by using vegetable oil as fuel for is engine (Pacific Biodiesel).
