What two conditions must be present for osmosis to occur?
Group of answer choices
1. equal solute concentrations on both sides of a membrane
2. disrupted membrane
3. high solute concentrations
4. a membrane that allows only solute to pass, but not the water
5. concentration gradient between the two sides of a membrane
6. low solute concentrations
7. a membrane that allows only water to pass, but not the solute
8. a membrane permeable to all molecules
Homework Answers
Answer:
5. concentration gradient between the two sides of a membrane
7. a membrane that allows only water to pass, but not the solute
Explanation:
Movement of water from a region of low solute concentration solution to a region of higher solute concentration solution through semipermiable (allows only water) membrane is called osmosis.

In many biological solutions, water is the solvent, meaning that solute molecules are dissolved in it (think of salt or sugar water). If a solute does not move across a semipermeable membrane, it is асr known an osmotically active solute. For the following examples, assume that the solute is osmotically active. In osmosis, water molecules move across the cellular membrane down the gradient (from an area of low solute/high water concentration to an...

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. Channels The integral proteins involved in facilitated transport are collectively referred to as transport proteins, and they...

Consider a secondary active transporter that uses symport for two molecules, X and Y. If X is the molecule being actively pumped and Y is present in higher concentration inside the cell, which of the following is true? (It might be helpful to sketch out the situation to visualize it better.) Xis present at higher concentrations inside the cell. X is being pumped from outside the cell into the cell. Xis present at higher concentrations outside the cell. Y is...

Which statements are true regarding reaction rates? [Select all that apply.] 1.Group of answer choices Larger activation energies are associated with faster reaction rates. 2.Higher reactant concentrations are associated with faster reaction rates. 3.Reducing the activation energy for a reaction increases its reaction rate. 4.Reaction rates depend on how likely molecules are to collide in the correct orientation to react. 5.Reactions that give off heat occur rapidly. Reactions that absorb heat occur rapidly. 6.Large changes in enthalpy are associated with...

b) Consider the following scenario: You start an experiment with equal concentrations of sodium chloride in a small tank. You are interested in studying the nature of a transmembrane protein embedded in a lipid bilayer. You insert the membrane, with embedded protein, into the tank, creating two sides, with initially the same concentrations of a solute on both sides (side A and side B). You leave the experiment for several hours and when you return you find that the solutes...
