Describe the net movement of water molecules when cells are placed in a hypotonic solution. Osmosis – The Movement of Water across a Membrane   Before starting, let’s see what you know about the terms hypotonic, isotonic and hypertonic. Examine the diagrams below. Note that the small green circles represent dissolved solutes like salt, glucose, and amino acids. You can assume that the […]

When cells are in isotonic solution, is there movement of water into or out of the cell? Osmosis – The Movement of Water across a Membrane   Before starting, let’s see what you know about the terms hypotonic, isotonic and hypertonic. Examine the diagrams below. Note that the small green circles represent dissolved solutes like salt, glucose, and amino acids. You

What concentration of salt is isotonic to animal cells Osmosis – The Movement of Water across a Membrane   Before starting, let’s see what you know about the terms hypotonic, isotonic and hypertonic. Examine the diagrams below. Note that the small green circles represent dissolved solutes like salt, glucose, and amino acids. You can assume that the additional space surrounding the

Define each term below in terms of solute concentration outside compared to the inside of the cell Osmosis – The Movement of Water across a Membrane   Before starting, let’s see what you know about the terms hypotonic, isotonic and hypertonic. Examine the diagrams below. Note that the small green circles represent dissolved solutes like salt, glucose, and amino acids. You can

Osmosis – The Movement of Water across a Membrane   Before starting, let’s see what you know about the terms hypotonic, isotonic and hypertonic. Examine the diagrams below. Note that the small green circles represent dissolved solutes like salt, glucose, and amino acids. You can assume that the additional space surrounding the solutes is water and that the tan area is INSIDE the

Briefly explain what active transport is and how it differs from passive transport, especially in terms of concentration gradients Diffusion – Movement of Solutes across a Membrane We will be using dialysis tubing to simulate a semipermeable membrane. This tubing allows small molecules (e.g., water, ions, glucose) to pass while preventing large molecules (e.g., macromolecules

What factors affect the movement of molecules across a semipermeable membrane? Which factor plays the greatest role in biological systems Diffusion – Movement of Solutes across a Membrane We will be using dialysis tubing to simulate a semipermeable membrane. This tubing allows small molecules (e.g., water, ions, glucose) to pass while preventing large molecules (e.g.,

Which solution, that in the bag or that in the beaker, is hypotonic compared with the protein solution Diffusion – Movement of Solutes across a Membrane We will be using dialysis tubing to simulate a semipermeable membrane. This tubing allows small molecules (e.g., water, ions, glucose) to pass while preventing large molecules (e.g., macromolecules like

Explain the movement or lack of movement of protein and glucose across the dialysis bag membrane Diffusion – Movement of Solutes across a Membrane We will be using dialysis tubing to simulate a semipermeable membrane. This tubing allows small molecules (e.g., water, ions, glucose) to pass while preventing large molecules (e.g., macromolecules like proteins, starch,

Summarize the results regarding the presence (+) or absence (-) of glucose and protein in the dialysis bag and beaker in Table 2 below Diffusion – Movement of Solutes across a Membrane We will be using dialysis tubing to simulate a semipermeable membrane. This tubing allows small molecules (e.g., water, ions, glucose) to pass while
