It carries energy around the cell to where it’s needed. ATP is synthesised from ADP and inorganic phosphate (Pi) using energy from an energy-releasing reaction e.g the breakdown of glucose in respiration. The energy is stored as chemical energy in the phosphate bond, the enzyme ATP synthase catalyses this reaction. ATP diffuses to the part of the cell that needs energy. Here it’s broken down back into ADP and inorganic phosphate (Pi).
It is a polysaccharide that functions as a carbohydrate store and is an important part of the human diet used as an energy source. It is a polymer of glucose sugar which means it is composed of many glucose molecules linked in a chain. Plants store the starch instead of simple sugars. Cellulose is an insoluble substance which is the main part of plant cell walls and vegetable fibres such as cotton. It is also a polysaccharide consisting of chains of glucose monomers.
Coloured Cellophanes effects on Photosynthesis Background Theory: For photosynthesis to take place a plant requires carbon dioxide, water, light, chlorophyll and a suitable temperature. The necessity of these factors can be demonstrated by simple experiments either on whole plants or leaves (Moment, Habermann 1973). Autotrophs are organisms capable of making their own food. Autotrophs are also called producers because they can use the energy in sunlight or chemicals to produce food. The process of photosynthesis is when plants use the energy in sunlight to convert water and carbon dioxide into oxygen and high-energy carbohydrates.
Introduction: Photosynthesis is the process by which plants, some bacteria use to make energy from the sun light to produce sugar. Photosynthesis is a reaction that is 6CO2+6H2O---C6H12O6+6O2. This reaction makes sugar that the plants eat, plants make their own food. There are two types of photosynthesis you have the autotroph and chemosynthesis. Now, autotroph is a reaction when it has sun light and chemosynthesis is where there is no light it lives in the bottom of the sea, this reaction use a chemical to make their own food.
If we didn’t have photosynthesis, we would not have oxygen in the atmosphere. What happens is photosynthetic autotrophs catches light energy from the sun, and it absorbs carbon dioxide and water from the environment and then it uses this light energy, which combines with reactants in order to produce glucose and oxygen, these are waste products. The glucose is stored, normally as starch and they then release the oxygen out into the atmosphere. Photosynthesis happens in the chloroplast, these are organelles of the plants and also of algae. The chloroplast is made of thylakoid membranes that is surrounded by what is called stroma.
Some enzymes act on one substrate only, while other enzymes act on a family of related molecules. Amylase is an enzyme that breaks starch down into sugar. Amylase is present in human saliva, where it begins the chemical process of digestion. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth. (Swann, 2008) The pancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and which are converted by other enzymes to glucose to supply the body with energy.
Digestive enzymes are hydrolytic enzymes. Their substances, or the molecules on which they act are organic food molecules which they breakdown by adding water to the molecular bonds, thus cleaving the bonds between the subunits or monomers. Digestive enzymes can function outside the body cells; their activity can be studied by test tubes (Marieb and Mitchell 2010). This experiment attempts to re-create the breakdown process that is normally done via digestion with Iodine as a vital component. It can be expected that once amylase reacts with the starch, maltose will then be broken down and less starch will be visible and more sugar will be apparent thus causing the solution mixed with iodine to become lighter and lighter.
Eating too much of one component can do as much harm as not eating enough of it. A balanced diet will have the right proportions of fat, protein and carbohydrates as they provide energy. They are all essential for the management of bodily functions. Our body cells convert nutrients into other components and are then used for metabolism and other cellular reactions. Starch, a major carbohydrate is converted to glucose and then reconverted into fat storage.
Photosynthesis and respiration are complete opposites, the only similarities is that they both produce energy. In photosynthesis the energy is produced when this reaction happens Sunlight Hydrogen + carbon dioxide Oxygen + Glucose 6CO2 + 6H2O C6H12O6 + 6O2 Glucose is made up of carbon, hydrogen and oxygen atoms. Glucose made by the process of photosynthesis may be used in three ways: 1. It can be converted into chemicals required for growth of plant cells such as cellulose 2. It can be converted into starch, a storage molecule, that can be converted back to glucose when the plant requires it 3.
The leaf disks float until their air bubbles are drawn out and replaced with the surrounding solution, causing their density to increase and the disk to sink. With enough light energy, photosynthesis will take place. Sugar will be made and oxygen will be released as a byproduct, causing the disks to float again. The rate of photosynthesis can be measured by the buoyancy of the leaf disk indirectly [AP Biology Lab Manual for Students].
