Electrolytes: Negative Or Positive Charge

This shows that these substances conduct electricity as a solid. The next test was conductivity as a solution. From our findings, sucrose had poor conductivity, while ascorbic acid and sodium chloride had good conductivity. Ascorbic acid conducts electricity because

Introduction: The aim of this experiment was to see whether water, Powerade or orange juice contained more electrolytes. Electrolytes are responsible for controlling the total amount of water in the body, regulating blood volume and maintaining muscle and nerve function. A lack of these electrolytes can cause headaches, fatigue, confusion, hallucinations and muscle spasms. I found that water and distilled water were less conductive than the orange juice and Powerade and orange juice proved to be the most conductive.

a. Almost every cell in our body uses calcium in some way. Calcium is one of best transporters of nutrients to your cells. Calcium is needed for our heart, muscles, and nerves to function properly and for blood to clot. It is also important for bone health. Ninety-nine percent of your body's calcium is stored in your bones.

This ensures smooth blood flow throughout the body. It further balances out the undesirable effects of excess sodium and supports good kidney function. Lowers high blood cholesterol

Energy is also needed to circulate blood, breath, take in oxygen, make new cells, grow, repair, and to transmit nerve impulses to react to changes in the environment. For example, moving quickly to get out of danger or recognising the best course of action to take in an emergency situation. Energy is also needed to build complex molecules such as enzymes and hormones from the simple molecules produced after we digest food and drink. A constant supply of energy is needed by the body and cells to enable all of these activities, and without this energy we would be unable to function as living beings.

They can balance hormones and brain chemistry. They can stimulate the regeneration of tissue and stimulate nerves. They can even carry nutrients to and oxygenate the cells.

Potassium is present in many food sources, and the typical person has high stores within the body. In activity and sweat, potassium losses are not as high as sodium. Calcium is the most abundant mineral in the body. Calcium has many roles both in normal body functions and athletic performance. When circulating in the bloodstream, it has a major impact on the metabolism of essential nutrients, and proper physiological functions.

Rationale The cell membrane, also called the plasma membrane is found in all cells and separates the extracellular side of the cell from the cytosolic side (Cell membrane (plasma membrane), 2023). The purpose of the cell membrane is to communicate with the cell’s external environment, to contain the cell’s contents and to control the transport of molecules in and out of the cell. Diffusion is the passive movement of molecules from an area of high to low concentration.

Dayma Padron Explain how the structure of the plasma membrane influences the movement of oxygen (O2), carbon dioxide (CO2) and sodium ions (Na+). The cells looks like tiny and insecure organisms in our body, but the reality is that without its perfect cellular organization, and essential functions, our body will be fragile, and we would live a short life. The plasma membrane, which is the wall of the cells, are composed of half lipids and half proteins, and about 5 to 10 percent of carbohydrates (Cooper, 2000). The membrane form a phospholipid bilayer, with fluid texture (cytoplasm), and acts like a barrier to protect its components from the outside neighbors, receptor, control mobility, maintain shape, and ensure that every part perform its

Cytoplasm is a specially organized solution of salt, nutrients, and complex molecules in water. The composition of cytoplasm may vary among different types of cells, but its purpose is the same – it provides a medium in which complex reactions can occur. For complex reactions to occur, cells need a source of energy.

Several other functions that it plays in the body include: balancing the electrolytes in our system, maintaining the acid-base balance and is significantly essential to muscle contraction and nerve transmissions throughout our body. A deficiency in sodium can put individuals at risk for contracting hyponatremia which is a dangerous condition in which an individual has too little sodium in their blood. The connection between sodium and water is directly correlated in keeping an equal ration of sodium and water in the body. For example, when the body contains too much salt, the body responds in keeping homeostasis by telling the individual to drink excessive water – polydipsia- until there is an equal balanced ratio of sodium to water. In addition, individuals who consume more than the recommended intake of salt tend to show signs of excessive weight gain, but in reality is just a side effect water weight in the body for this its way of maintaining a balance ratio until the salts are expelled from the body.

Prelab: In this lab report, the elements being discussed are about; the study of charging by friction, induction and conduction. The material being used to demonstrate the study in this lab are: Pith ball electroscope, ebonite rod, glass rod, wool and plastic. The lab also talk about the law of Electrostatic in the table # 1 as the procedure of charging the ebonite rod with the wool and plastic with the glass rod then looking at how the charge affect the pith ball as toward the charge ( attract or repel ). The safety concerns that are likely to occur are that the ebonite and glass rods will be tapped against other objects, causing them to break and causing an injury.

In this lab when looking at cells, we observed the salinity and osmolarity of the cell when placed in the environment. With the different concentrations of NaCl, we are able to see how different environment can constrain an organism and see the wide range of responses to regulate in cell’s osmolarity. The cells we studied was sheep red blood cells (erythrocyte), because they are the most studied membrane system and therefore used as ideal membrane to study the relationship between water and the passing of the different concentration of NaCl across the membrane. The purpose of the experiment was to observe the cell and infer which direction of the flow of the water due to the cell volume change.

In today’s society, we use electricity for everything. We use it for different things like making various appliances in our homes, stores and businesses to work, to advance and improve technology and help to make people lives better. It can also be used as a form of medical treatment. This form of treatment is called electrophysiology or galvanism during the 18th and 19th centuries. Electrophysiology is a part of physiology dealing with the electricity that is associated with body functions.

This means there is no movement of ions in or out of the cell membrane and a resting potential is attained. At this point, there are more sodium ions outside the cell membrane and more potassium ions inside the
