A Discussion on the Reasons for the Elimination of Sugar from Our Daily Diets
Words • 1713
Pages • 7
Sugar has become a very important part of our routine diet. It is so entwined with our diets that one cannot easily eliminate sugar directly from their food. This increased intake of sugar has become reason of various diseases and health risks like diabetes, obesity, overloading the liver and many more. This paper will discuss some solid reasons why it is necessary to eliminate sugar from our daily diets to prevent health risks. It will also give a brief idea…...

To understand the culture of the Upper Paleolithic period we must first understand what exactly is culture and what exactly is the Paleolithic period. Culture by definition is “a shared way of life that includes material products, values, beliefs, and norms that are transmitted within a particular society from generation to generation” (Scupin, 2016) it is also one hundred percent learned.

Antibody recognizes the foreign particles called antigens (Ag). These are mainly protein in nature. B-cell receptor and / or antibody binds to a particular region of antigen called B-cell epitope. B-cell epitopes are the amino acid sequences of an antigen, which interact with antigen biding region (called paratope) of antibody. Process to identification of these antibody interacting sequences of antigen called B-cell epitope mapping. Identification of B-cell epitope is the main basis for peptide based vaccine production, development of immunodiagnostic…...

Photosynthesis Process in Plants
Words • 371
Pages • 2
What happens to carbon atom during photosynthesis?(Light dependent reactions) ·Light depended reactions occur inside the thylakoids. When the chlorophyll molecules absorb sunlight they give off high energy electrons. They move through a series of electron carrier proteins called electron transport chains in the thylakoid membrane. The proteins in the electron transport chain use the energy to pump hydrogen ions into the thylakoid from the surrounding stroma. The stroma is the gel like fluid inside the chloroplast. The hydrogen ions pumped…...

Investigating the effect of temperature on the rate of photosynthesis
Words • 8156

Before starting my investigation on how temperature affects the rate of photosynthesis I carried out some research into photosynthesis. From this initial research I made a prediction based on the evidence that I found about the enzyme rubisco that is used in the dark stages of photosynthesis, and also on the limiting factors of light intensity, carbon dioxide concentration and temperature. I then went on to carrying out a preliminary experiment from which I learnt the factors that made the…...

The Rate of Photosynthesis on Plants
Words • 224
Pages • 1
When organisms like cyanobacteria, algae, and primarily green plants use the energy from light and turn this energy into carbon dioxide, or water into oxygen and sugar, this process is called photosynthesis. The equation for photosynthesis is 6C02 +6H20+light energyв†’ C6H12O6 + 6O2 (Newton, 2019). The sugar created is stored in the starch. Starch is then used as fuel for plants, these are heterotrophs and autotrophs (Newton, 2019). In photosynthesis, there are two stages that are light-dependent. Light-dependent means that…...

Aerobic respiration is the process for transforming Glucose into Co2(Carbon dioxide). and H20(Water as waist product) with the participation of oxygen (O2) for produces energy. As a function, aerobic respiration provides fuel for the repair, growth, and maintenance of cells and tissues. It is the process by which many cells, produce energy using nutrients and oxygen. It also gives rise to carbon dioxide, which later must then release. (equation a mettre). This equation explains why both nutrients and oxygen are…...

Role of Forest in Carbon Cycle
Words • 1303

Carbon dioxide (CO2) is the most abundant human-influenced greenhouse gas. A greenhouse gas is found naturally in the atmosphere— in the upper atmosphere it captures sunlight energy and reflects it back to earth, in turn creating heat. This "blanket" of gas moderates the earth's temperature. With increasing levels of carbon dioxide, however, research suggests that a thicker blanket will produce global warming. Carbon dioxide is an important molecule for life. All plants that photosynthesize absorb CO2 from the air, combine…...

At the end of the 1930s, a group of chemists proved that natural rubber degradation is due to successive and destructive attacks of atoms or unstable molecules, ie free radicals. Any matter, consists of infinitesimal particles: the atoms. At the core of these atoms are the protons and the neutrons, and the electrons rotate around it, which couple together, forming a relatively stable combination. Free radical is a molecule that has lost an electron with electric charge, eager to mate,…...

How to protect iron from rusting?
Words • 357

To investigate the ability of metals to act as a sacrificial protector of iron, preventing or reducing rusting. Theory Iron oxide is more stable than iron metal, so when given the opportunity iron will be readily oxidised. Iron reacts with oxygen and water to form a hydrated form of iron(III) oxide (Fe2O3i?? xH2O), known as rust, which is permeable to air and water so the metal underneath the rust layer continues to corrode. The iron atoms readily give away two…...

Standard enthalpy change of combustion is the energy change that occurs when 1 mol of fuel is completely burnt in oxygen under standard conditions. However, it is impossible for substances to be burnt under standard conditions. The enthalpies of combustion are different depending on the number of carbons and hydrogens in each substance. For example, the enthalpy combustion for methane is -890 kJ mol-1, however the enthalpy change of combustion for ethane or propane will be greater because more bonds…...
