1. Diagram an individual phospholipid and a bilayer of phospholipids. Label the hydrophilic head, and hydrophobic tails in both. 2. Explain the Fluid Mosaic model of the cell membrane and describe the functions of the proteins that are embedded in the membrane. The Fluid Mosaic model of the cell membrane is a hypothesis that describes the phospholipid bilayer and it proteins. It states that the membrane is flexible - fluid - and has various proteins embedded in it - a mosaic. These structures…

1a. The results from Figure 1 illustrate that the control treatment of the Tomato plant, has a maximum quantum yield of Photosystem II than chilled plants. It appears that over time, the average Fv/Fm seems to be constant with no drastic changes in the levels, with values staying between the ranges of 0.7 to 0.8 Fv/Fm. On the other hand, the chilled treatment of Tomato plants begins at 0.2257 Fv/Fm at time = 0 minutes, and the last plant has a Fv/Fm value of 0.6526 when time is at 150 minutes.…

INTRODUCTION: Exercise 3.1 - Osmosis: Toward the start of lab, we found out about diffusion which can happen as active transport or passive transport. Diffusion is known as delivering a net development of solute particles from locales of higher focus to districts of lower concentration. Active transport is the development of an atom over the plasma layer. Active transport is when atoms move against their focus slopes. We discovered that dynamic transport requires vitality, and the motivation…

Diffusion in Agar Cubes Experiment Introduction Diffusion is a paramount process to organisms because molecules enter the body cells and waste products are removed. Diffusion is the movement of particles from regions with dense areas to regions with lower density. Diffusions rate can be determined by many factors this includes, the size, synthetic composition, concentration gradient, surface area to volume ratio. The independent variable in this experiment is the size of the agar, this means…

In this experiment I attempted to created and study the affects of a egg in a hypertonic and hypotonic solution. To conduct this experiment I used the following materials: cups, eggs, vinegar, corn syrup, spoons and food coloring. To begin the experiment I placed three eggs in vinegar to dissolve their shells, leaving behind a thin membrane that allowed water to pass in and out of the eggs. The water molecules enter inside the eggs and the eggs begins to swell. Once the eggs have sat in the…

In this lab, the effects of osmosis on an egg without a shell will be observed; an egg will be submerged in water and then corn syrup. Osmosis, the process of water moving from a low concentrated area to an area of high concentration, is the main theme of this lab. The purpose of this experiment is to view the effects of an egg in a hypertonic state, hypotonic state, isotonic state and diffusion. Hypertonic is the movement of water leaving the egg to an area of higher concentration. When this…

With A = 52.4, and B =119.8. Moreover, some previous works overlooked that the increase in temperature is always accompanied by the increase in water vapour pressure, and lower CO2 partial pressure respectively. Consequently, according to Henry’s law, the amount of dissolved CO2 in water is also decreased. Thus, the increase in temperature will increase the kinetics of precipitation, and also reduce the supersaturation of FeCO3 as a result of lesser amount of dissolved CO2 in the water. B.…

innate protein particles or aggregates.However, there is a mechanistic difference between the two aspects. In the case of a pure solubility issue, i.e. a protein becomes insoluble in a certain solution (no changes in protein structure and integrity) and a solid phase is formed, a strong dilution of the system may lead to the dissolution of the protein. In such a circumstance, the term “protein associates” may more appropriately describe the formed protein solid .In this instance, protein…

experiment B of exercise 1,the students will investigate the process of osmosis and diffusion in a model membrane system and the effect of solute concentration on water potential, the force created by both physical pressure and solute concentration, as it relates to living plant tissues. Diffusion is the passive movement of molecules or particles from a region of high concentration to an area of low concentration. Particularly, osmosis, a special type of diffusion, is the diffusion of a solvent,…

Different Concentrations of Saline Solutions Impacting The Mass of The Baggies Research Question: Will the different concentrations of the saline solutions impact the mass of the baggies due to the effect of osmosis. Independent Variable: The concentration of saline in each solution. Dependent Variable: The mass of the baggies(g) What needs to be controlled: The type of solution in bags. The amount of solution in cups…
