When would a carrier protein be required in order to allow a solute to diffuse across a plasma membrane
The cytoplasm of a certain cell is composed of a solution that is 98% water, 2% solutes. Consider the solution shown in the beaker in this picture: FOOE OOS Foor solution. [Select] Cytoplasm is 98% water, 2% solutes. The solution in the beaker would be considered when compared to [Select] The plasma membrane is impermeable to solutes. Beaker solution is 98% water, 2% solutes the cell. We would expect that the cell would [Select] if it was placed in the would account for whatever changes might occur to the volume of the cytoplasm of the cell when it is placed in the solution.
Name the membrane transport mechanism that Ca2* would most likely use to diffuse across the membrane. O simple diffusion O active transport O facilitated diffusion O vesicular transport O more than one of the above
Which of the following characteristics may be used to describe Active Transport? Select all that apply. occurs without a transporter protein requires an energy source shows saturation kinetics (has a maximum rate) can occur against a concentration gradient (i.e. uphill)
Passive transport across the membrane mediated by a carrier— would not be saturated by increasing amount of substance to be transported. does not require energy (ATP). can be driven in reverse. moves the solute through the membrane in the “uphill” direction of their concentration gradient. is faster than transport mediated by channel proteins.
As a cell grows its plasma membrane expands. Does this involve endocytosis or exocytosis? ATP is not directly involved in the functioning of a co-transporter. Why, then, is co-transport considered active transport?
What type of cellular transport do Epithelial sodium channels (ENaC)s perform? Group of answer choices Simple diffusion Secondary active transport Facilitated diffusion Primary active transport
Can you create a diagram/flow chart of membrane transport? The diagram must contain both active and passive transport.
What is the Description and Examples in the body of these Cell transport? Explain in 2-3 sentencesDescription:Examples in the body: a. Diffusion b. Osmosis c. Facilitated Diffusion
Which of the following is correctly paired? Two answer choices are correct. osmosis= a type of active transport facillitated diffusion = a transport proteins are used to move substances across a membrane diffusion = a type of passive transport
Discuss why the following affect the rate of diffusion:molecular size, temperature, solution density, and thedistance that must be traveled.
Statement 1: The direction of diffusion of a solute across a membrane is determined by its concentration gradient and always moves toward equilibrium. Statement 2: In passive transport, solutes move down the gradient from a region of low concentration to a region of high concentration. A Both statements are true. Both statements are false. C) Statement 1 is true. Statement 2 is false. Statement 1 is false. Statement 2 is true.
