Question

Which of the following statements about passive transport is correct? a. Passive transport permits the solute to move in either direction, but the net movement of the population of solute molecules occurs down the concentration gradient of the molecule. b. Passive transport operates independently of diffusion. c. In passive transport, solute movement stops when the solute concentration is the same on both sides of the membrane.

Answer 1

The correct answer is option a, which states that passive transport permits movement of solutes both ways but net movement is down the concentration gradient. Passive transport involves diffusion and facilitated diffusion and doesn't require energy. This transport continues even at equilibrium as molecules maintain the concentration balance.

Step-by-step explanation:

The correct statement about passive transport is a. Passive transport permits the solute to move in either direction, but the net movement of the population of solute molecules occurs down the concentration gradient of the molecule. This means that solutes move from an area of higher concentration to an area of lower concentration until the concentration equilibrates. Passive transport, which includes diffusion and facilitated diffusion, does not require cellular energy to move substances across cellular membranes.

Facilitated diffusion is a type of passive transport that uses specific transport proteins to move molecules that cannot easily pass through the cell membrane. It is important to note that passive transport continues even once the concentration of solute is the same on both sides of the membrane because molecules continue to move in both directions, maintaining equilibrium.

Answer 2

C. In passive transport, solute movement stops when the solute concentration is the same on both sides of the membrane

Step-by-step explanation:

Passive transport is how is called to the movement of atomic or molecular substances across cell membranes without the use of energy. There are different types of passive transports, the four main kinds are diffusion, osmosis, facilitated diffusion and filtration.

The correct statement is the C and is talking about the type of transport called diffusion, this net movement drives material from an area of high concentration into another with lower. This difference between the areas is called the concentration gradient and the passive transport would stop when both sides are balanced.

I hope this answer helps you.
