All enzymes are under the class of protein biomolecule. Amino acids are the basic units that are combined to make up an enzyme. The biomolecule that stores information is a Nucleic Acid. The specific 3-D region within an enzyme is called the active site. The chemical

In order to learn more about macromolecules, we performed an organic compound experiment. The purpose of this experiment is to find and test the presence of carbohydrates(Starch & Sugar) and proteins in different food using tested distilled water as indicators(independent variable). Food that will be tested in this experiment are cookies, milk, hot dog, pretzels, applesauce, cake mix, popcorn, and potato. My hypothesis is that if the food listed are tested for carbohydrates and proteins, then most of them with the exception of water, will be positive. Materials that will be used in this experiment are 8 regular test tubes, cookies, milk, hot dogs, pretzels, applesauce, cake mix, popcorns, potatoes, tap water, 500ml pyrex measuring cup, Benedict’s solution, Biuret solution, and Iodine solution.
Kylinn Walston RADT 3143 Chapter 1: Cellular Biology 1-1. Explain how the structure of the plasma membrane influences the movement of oxygen, carbon dioxide, and sodium ions. a. The plasma membrane is extremely important because of its multi-functionality to each cell, it is what keeps the cell complete. The membrane structure is determined by the lipid bilayer, and proteins determine the membrane functions. The membrane has a lipid bilayer containing hydrophobic and hydrophilic regions. This bilayer blocks hydrophilic substances from passing while still allowing water diffusion.
1. What type of macroscopic evidence for chemical change did you observe during this experiment? Give at least three different examples. (15 points)
All dietary fats stem from the plant and animal based foods that
The net energy value for proteins is 4.0 kcal, Carbohydrates 4.0 kcal, and lipids 9.0
“Life is meant for spectacular adventures. Let your feet wonder, your eyes marvel, and your soul ignite.” Since finishing my science fair experiment, I have been looking at new experiments and ways to further my project on slime molds. In the future, I would like to do an experiment using slime molds and how they grow in different surroundings. Specifically, I would like to see how Physarum Polycephalum reacts to different lighting and how/if it reacts to different sounds.
A slime mold is an informal name given to several kinds of unrelated eukaryotic organisms that can live freely as single cells, but they can come together to form multicellular reproductive structures. They were originally classified as fungi but they are no longer considered part of that kingdom any more. The acraiceae have a common characteristic of all forming a simple fruiting structure from the emergence of a unicellular amoeboid stage followed by a multicellular pseudoplasmodial stage. Stalk cells and spores are differentiated from the cells that develop in the fruiting structure. Sorocarpic amoebae also referred to as cellular slime molds, are heterotrophic amoeboid organisms.
11. Explain how certain amounts and types of food can affect hunger and satiation. (max. 2 marks) The type of macronutrient a person consumes affects hunger and satiation, for instance, proteins have the strongest effects of satiation compared to carbohydrates and fats. Also, solid products that are rich in water and fibre have greater satiety values rather than those that don’t contain these characteristics.
Each DNA molecule is made up of two strands which intertwine to form a double helix. The form of the stucture which looks like a ladder is each nucleotide base is a DNA strand which links with another nucleotide base via hydrogen bonds in a second strand of DNA. The bases cross link in a certain order such as A adenine will only link with T thymine and the other way around then C cytosine will only link with G guanine and the other way around. When reproduction is formed from parents to off spring more genetic materials are needed the 2 stands unzip and enzymes add new bases to each which then form 2 new strands. Different segments of a DNA molecule code for different characteristics in the body.
Particles are labeled in many ways. One way particles are referred to be as atoms (elements). They’re identified by their properties, number or protons and neutrons and atomic number. Another way particles are referred are as molecules (covalently bonded- nonmetal to nonmetal). For example, water is a molecule because it’s composed of nonmetals.
Testing for the Presence of Macromolecules in McDonald’s Happy Meals Clayton Wagoner MST Biology White 4 duPont Manual High School Introduction Carbohydrates, lipids, proteins, and nucleic acids are organic molecules found in every living organism. These macromolecules are large carbon based structures. The macromolecules are assembled by joining several smaller units, called monomers, together through a chemical reaction called dehydration synthesis. The resulting polymer can be disassembled through the complementary process called hydrolysis.
Included among these fats are peanut oil, canola oil, and olive oil. Polyunsaturated fats include some fats from vegetable sources, as well as fats derived from fish. Among polyunsaturated fats are safflower and corn oils. These provide Omega-6 fats. We get Omega-3 fats from fish
When it comes to lipids, there can be many misconceptions on what is true and what is false about them. For instance, before reading this chapter I thought saturated fats and trans fats were essentially the same thing. I thought trans fats were just another form of saturated fats. All I remember being taught about these two fats were that they were bad for you and you should never eat them.
