LO 2.1 I understand that free energy, the portion of a biological system’s that can perform work when temperature and pressure are uniform throughout the system, is used in systems to cause change. I also understand that empirical data proves all organisms require a constant energy output to maintain organization, to grow, and to reproduce. (Campbell 119-123) LO 2.2 I understand that although free energy is always required in living systems in order to maintain organization, to grow, and to…

Like cars, humans need fuel for energy. While cars use gas for energy, humans use nutrients for energy such as proteins, lipids, and carbohydrates. Proteins, lipids, and carbohydrates are the macronutrients the body need to function smoothly and properly.Out of the three macronutrients, carbohydrates is the main source for energy, it is the body's main source of fuel, and the nutrient use for brain function and organ operation. Unlike proteins and lipids,carbohydrates is easily digested and can…

Lead Identification (LO): Lead compounds bind to target receptors, and shows potentially therapeutic pharmacological activity, and may contain similar structures and functional groups. Lead compounds are used as a foundation for drug development and may be modified structurally for greater pharmacodynamic efficiency and potency.1 One source of determining lead compounds is by assaying libraries through HTS. Researchers analyze the drug’s ADME properties (Absorption, Distribution, Metabolism, and…

Number6. This is known as the ‘goddess’. Start with hands straight over your head in mountain position. Then spread your legs apart and bend them until you can feel your thighs being parallel to the ground. Spread your hands on the both side of your head and lift them up at a ninety- degree angle. Hold onto this position for at least 10 seconds for five rounds. Number7. Stand straight. Now, lean on the left side with your left elbow touching the left knee. Swing your right hand over your head to…

I. PURPOSE The purpose of this lab was to observe the physical properties of different samples of matter and to use your observations and knowledge of chemistry to classify each sample as an element, a compound or a mixture. II. MATERIALS 10 beakers containing different samples of matter III. PROCEDURE First off, put on a laboratory apron. Then, take a few minutes at each lab station and record three physical property observations of each sample of matter. Record the three physical property…

leucine to proline at amino acid position 1544(Ashcroft, 2005). This mutation simply reduce the activation of the channel by stimulatory nucleotide MgADP, as the NBDs sensitivity to this nucleotide is greatly/entirely lost. The failure of the channel activation means the open state of the channel pore is greatly reduced/blocked. This occurs as the inhibitory nucleotide (ATP) would have higher affinity for the channel than the activating nucleotide (MgADP). Closure of the K+ channel leads to…

In our experiment we evaluated which liquid yeast would produce gas the fastest by measuring how long it took for certain liquids to inflate a balloon. We hypothesized that if the yeast and sugar were placed in a warm,sugary environment like apple juice, then the yeast will produce more CO2 and cause the balloon to inflate faster. The control was the room temperature Throughout the experiment the type of balloons, size of the erlenmeyer flasks, amount of yeast, volume of each liquid, and the…

Introduction Homeostasis is the state of a stable internal cell environment. If the cell is not in a state of homeostasis, then the cell will not be able to live and function properly. The plasma membrane is selectively permeable and controls what molecules enter and exit the cell. The plasma membrane keeps the environment inside the cell relatively stable which is the state of homeostasis. The goal of this investigation is to see if the size of the cell is affected when the cells are put in…

A group of biologists have developed a general model to explain growth and development in ectothermic organisms. Changes in environmental temperatures effect the rates of most biological reactions and biological processes in ectotherms. The rates of ontogenetic growth and development are no exceptions. Ectothermic animals develop faster at warmer temperatures and they usually mature at smaller body sizes. This phenomenon has been called the temperature size rule (Zuo et Al. 2011). The…

How can we differentiate acids and bases? How do we know if a substance is an acid or a base? There are different methods to discover whether a substance is an acid or a base. One of the methods is by using an acid-base indicator or by identifying hydrogen or hydroxide ions in a substance’s chemical formula. Certain materials such as a plastic template, red litmus paper, blue litmus paper, phenolphthalein, universal indicator, and a pH chart can be used to help us distinguish acids and bases.…
