Molecule

water and also the soil. Water is a molecule made up of the following atoms, Hydrogen and Oxygen. In this molecule the electrons are not shared equally between these atoms. Electrons are negatively charged so if they spend more time around an atom the atom becomes negative. The electrons turn Oxygen negative because they spend more time together. The reason for the electrons to be around Oxygen is because Oxygen has more electronegativity. Water is a polar molecule due to the fact that its…

visible to the human eye as a colorless liquid with a clear odor that could be described as irritating or distinct. The aqueous molecule can be broken apart fairly easily, as it is a very unstable molecule with a bent shape. When coming in contact with certain organisms’ tissues and organs, H2O2 is broken down by catalase to prevent major damage to the tissues. The molecule is broken down by the body, but it is also produced by organisms, especially humans. According to Niethammer (2009),…

active transport Bulk transport: Exocytosis: a vesicle containing the molecule fuses with the inside of the plasma membrane and the molecule is expelled. Endocytosis: The membrane recognises and binds with a molecule in its environment. The fluid membrane then forms a vesicle around the molecule, and the sac enters the cell. Phagocytosis and pinocytosis are examples of endocytosis. Passive transport is the movement of molecules down the concentration gradient, which means movement from an area…

refrigerator will cool the fastest because they think that since there are more molecules present, it will cool faster. Others may recommend that freezer would do better because the molecules are colder, therefore less spread out. Although, the air molecules from the refrigerator and freezer must cover a bigger area of space which means that those air molecules are going to be less dense. When using only the ice cubes the molecules are going to be closer together which will increase the…

special proteins known as the porins. The porins are integral membrane proteins and they allow the movement of molecules that are of 5000 daltons or less in weight to pass through it. The outer membrane is freely permeable to nutrient…

In experiment 1.1, we studied the relationship molecule size has with diffusion rate. Our hypothesis claimed that smaller molecules will travel farther across the agar plate given the same duration of time. Based on the data collected, our hypothesis was proven true. Potassium permanganate has a molar mass of 158 g/mol, methylene blue 319.85 g/mol, and potassium dichromate with 294.185 g/mol. Potassium permanganate diffused the farthest, potassium dichromate second, and methylene blue secured…

phosphate and deoxyribose backbone, and four different nitrogenous bases. These bases are adenine, guanine, cytosine, and thymine. Ribonucleic acid, the molecule formed in the transcription of DNA, is made up of phosphate, ribose, and adenine, guanine, cytosine, and uracil. The backbone of DNA consists of a phosphate bonded to a deoxyribose molecule. Deoxyribose is a sugar containing five carbons, and it is called deoxyribose as it is missing an oxygen atom on C2. The sugar found in RNA is…

When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration. For example, if the cell is submerged in saltwater, water molecules move out of the cell. If a cell is submerged in freshwater, water molecules move into the cell. When the membrane has a volume of pure water on both sides, water molecules pass in and out in each direction at the same rate. There is no net flow of…

Melting point is the technique that disrupts the IMAF’s and forces the molecule to break by adding thermal energy to increase kinetic energy to the compound. When melting the unknown the interactions within the IMAF’s of the molecule are decreasing causing a disruption within the structure of the lattices. Determining the melting point of Unknown 105 A helps narrow down the possible compound that it can be, by the given melting point range. The narrower the range represents the relative purity…

Triglycerides are made of three molecules of fatty acid molecules and a glycerol molecule and its catabolism follows two pathways to generate ATP. The four molecules are separated by a hydrolysis degradation reaction. The three fatty acid molecules enter a pathway that consists of Beta oxidation, Citric Acid Cycle, and electron transport chain. The substrate involved in Beta Oxidation include the three fatty acid molecules, coenzyme A, NAD, FAD, and ATP. The Beta Oxidation process involves…
