Effects of Temperature on Beetroot Cell Membranes Background Information: A cell membranes is a thin structure that surrounds the whole cell. It contains the cytoplasm of a cell. The cell membrane is made up of hydrophilic region and a hydrophobic region. The hydrophilic region likes water‚ it is on the outside of the cell‚ the hydrophobic region is the inside of the cell where its protected from H2O. The cell membrane’s outer surface lets larger molecules into the cell. The inner surface deals

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Because of the selective permeability of the membrane only water and other very small particles (iodine) can be diffused through simple diffusion. The solution out of the dialysis tubing had a higher distelled iodine concentration of solutes (iodine + H2O) than did the starch solution. So iodine move into the cell and react with starch molecules to formed starchiodine‚ the blue compound

ARTIFICIAL NEURAL NETWORK: USE IN MANAGEMENT Neuron Transfer Function: The transfer function of a neuron is chosen to have a number of properties which either enhance or simplify the network containing the neuron. Crucially‚ for instance‚ any multilayer perceptron using a linear transfer function has an equivalent single-layer network; a non-linear function is therefore necessary to gain the advantages of a multi-layer network. Types of neuron transfer function • Pure Linear Transfer Function

1a. Aquaporins are membrane proteins that have fourteen various structures however the most common form is that of a homotetramer. The homotetramer is often found in the membrane and composed of four aquaporin membranes. The structural arrangement creates a fifth channel in the middle that allows for gas transportation. 1b. The direction of H2O molecular flow through a channel is determined by an osmotic gradient. 1c. One of the mechanisms that prevents proton channeling is due to the (ar/R) and

A multitude of different movies portrays Artificial Intelligence (AI) as something to be feared; an entity that would be the demise of humanity. Despite what these movies portray‚ it is up for dispute whether AI is a threat to humanity. AI is becoming more commonplace and more advanced everyday both in the real and virtual world. Multiple different AI entities have previously malfunctioned and caused issues. A multitude of groups of individuals feels that restrictions should be placed on AI entities

understanding on how osmosis and diffusion works. In its simplicity‚ it explains the process that our bodies (mainly cells) use all the time. It also showed me that even with the temperature changing‚ it doesn’t drastically change the rate of diffusion. Introduction Diffusion is important in all living systems. Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration (Purchon 1). Diffusion is the movement of a substance

respiration. In the presence of oxygen‚ pyruvate or fatty acids‚ can be further oxidized in the mitochondria. Each mitochondrion is enclosed by two membranes separated by an intermembrane space. The intermembrane space extends into the folds of the inner membrane called cristae which dramatically increase the surface area of the inner membrane. Cristae extend into a dense material called the matrix‚ an area which contains RNA‚ DNA‚ proteins‚ ribosomes and range of solutes. This is similar to

Investigating the effects of temperature on cell membranes Independent variable: Temperature of beetroot Dependent variable: Absorbency of light Hypothesis: As temperature rises to its optimum temperature‚ the absorbency of light will increase because protein is an enzyme and will therefore be affected by temperature. This is because more beetroot dye will pass through the cell membrane and then into the distilled water. The deeper the colour of the beetroot dye‚ the higher the absorbency

To investigate the effect of variation in temperature on the permeability of cell membranes using fresh beetroot Aims In this investigation‚ you will subject fresh‚ washed beetroot discs to different temperatures to investigate the effect of temperature on the permeability of the plasma membrane. Overview The beetroot discs will be placed in distilled water at different temperatures. You will compare the intensity of the beetroot pigment that has leaked out from the cells subjectively and possibly
