Water is moving into the sac by osmosis. True or False: If there are a sufficient large number of transport proteins present, glucose can be transported from a solution of lower concentration to a solution of higher concentration i. Yes, if you put the same amount of glucose in the right beaker as in the left. Facilitated Diffusion follows the same rules as regular diffusion higher to lower. I used 500 protein carriers, and I set the amount of glucose solute to be delivered to the beaker at 2. Adenosine triphosphate, Cell, Diffusion 8945 Words 31 Pages to a low concentration gradient.

Bowman's capsule, Distal convoluted tubule, Efferent arteriole 633 Words 3 Pages Membrane Permeability Aim To determine the effect of various chemicals and high temperature on the membrane permeability of beetroot Hypothesis Organic solvent and high temperature will destroy the cell membrane and make it permeable to the red pigment. Predict Question 2: What will happen if you increase the pressure above the beaker the driving pressure? Use an analogy to support your statement. Also, per the Honor Code, this work must be your own. For this I will use the cell of a beetroot. Book's Author: Stabler, Zao Location sources:. The larger value obtained when more glucose carriers were present corresponds to an increase in the rate of glucose transport.

This may also be applied to the study of transport mechanisms in living membrane-bounded cells. Absolute zero, Cell, Cell membrane 661 Words 4 Pages Cell Unit Notes I. Activity 2: Observing Diffusion of Dye Through Water p. You were asked to predict what effect you thought that adding Na+ Cl- would have on the glucose transport rate. The filtrate flows from the Bowman's capsule into the renal tubule called the proximal convoluted tubule then into the loop of Henle, and finally into the distal convoluted tubule: a.

Albumin is a protein with 607 amino acids. This was because the high concentration of Na+ Cl- in the right side of membrane gives a increased force to water in left beaker to move towards the solution with the highest concentration of solutes. Which of the membranes can it pass through? How does it compare to your baseline data, and why? What do you think would happen to the osmotic pressure if you replaced the deionized water in the right beaker with 9. Brown, Cell membrane, Color 609 Words 3 Pages Exercise 1: Cell Transport Mechanisms and Permeability Worksheet Assignment Due: Week 2 Student instructions: Follow the step-by-step instructions for this exercise found in your text and record your answers in the spaces below. Respiration - Able to generate energy for life processes. The cell membrane contains a phospholipid bilayer which causes the cell to have selective… 1319 Words 5 Pages and large polar molecules such as glucose are not permeable to the membrane.

Now we are starting to think that it is spread unevenly, more like a mosaic than a layer. Explain the effect that increasing the Na+Cl- concentration had on osmotic pressure and why it has this effect. The filtration rate of Na+Cl- in the simulation was dependent on a. The size of the molecule. True or False: Osmosis is considered a type of passive transport, i. There are two main types of passive processes called diffusion and filtration. The smaller the molecular weight, the faster the rate of diffusion.

The effect of increasing the concentration of sodium chloride from 9 mM to 18 mM in the left beaker was to You correctly answered: b. If you put the same amount of glucose in the right beaker as in the. Thyroxine is You correctly answered: c. I will not go into. Lab 1: Cell Transport Mechanisms and Permeability Purpose The purpose of this experiment is to have a better understanding of the subject matter and to understand the difference between active and passive cellular transport. And the transport rate for NaCl is much higher than glucose. The filtrate You correctly answered: d.

If the membrane is composed of lipid portion. Proton transport mechanisms include combinations of the Grotthuss mechanism, masse diffusion, migration, surface site hopping along sulfonic… 1362 Words 6 Pages Lab 1: Cell Transport Mechanisms and Permeability Purpose The purpose of this experiment is to have a better understanding of the subject matter and to understand the difference between active and passive cellular transport. They did not pass through because the solute mass was greater than twenty. Facilitated diffusion relies on carrier proteins, and occurs when molecules are either not lipid soluble or are too large to pass through the pores of the membrane. How well did the results compare with your prediction? In other words, explain why you picked the choice that you did. The Na+ transport rate stops before transport has completed. The molecules have to rely on carrier porteins which varies in number due to the available membrane transport.

Why did you pick the choice you did? Add K+Cl- to the beaker on the left. The larger molecule will diffuse more slowly than the smaller molecule. Describe two Variables that affect the rate of diffusion. Obtained was the understanding of the changing of the molecular weight cut off in a membrane, and how it does not play a part directly in changing the rate of diffusion, but instead determined if diffusion was accomplishable at all. Chemistry, Concentration, Diffusion 1828 Words 6 Pages also rising. Hypothesis I believe the plasma membrane is selective about what is able to and not able to pass. If you put the same amount of glucose in the right beaker as in the left, would you be able to observe any diffusion?
