Movement Across The Cell Membrane: Trivia Quiz! - Quiz

Movement of substances across the cell membrane is an important process within a cell. The movement can either be through diffusion or osmosis, and we got to cover how these processes take place in our past classes. Take this test for a drive and get to see just how much you understand the process as a whole. All the best!

Questions and Answers

1.

Please fill answer below_______ Movement of water across a membrane from a less concentrated solution to a more The concentrated solution is called

Explanation
Osmosis is the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this process, water moves in order to balance the concentration of solutes on both sides of the membrane. The term "concentrated solution" refers to the side of the membrane with a higher solute concentration, which attracts water molecules through osmosis.

2.

____________________ is the movement of a substance to an area of higher concentration to An area of lower concentration.

Explanation
Diffusion is the process by which molecules or particles move from an area of higher concentration to an area of lower concentration. This movement occurs due to the random motion of particles, which leads to a net movement from areas of high concentration to areas of low concentration until equilibrium is reached. In diffusion, there is no need for external energy input as it is a passive process driven by the concentration gradient.

Use of a carrier protein that transports molecules through membranes to an area of lower concentration is called ____________________ ____________________________.

Explanation
Facilitated diffusion refers to the process in which a carrier protein assists in the movement of molecules across a membrane from an area of higher concentration to an area of lower concentration. This type of transport does not require energy and is driven by the concentration gradient. The carrier protein acts as a channel or a transporter, allowing specific molecules to pass through the membrane. This process is important for the transportation of larger or charged molecules that cannot easily diffuse through the lipid bilayer of the membrane.

____________________ uses hydrostatic pressure to transfer water and solutes through a membrane from an area of higher pressure to lower pressure.

Explanation
Filtration is the process that uses hydrostatic pressure to transfer water and solutes through a membrane from an area of higher pressure to lower pressure. This process is commonly used in various applications such as water purification, kidney function, and industrial filtration systems. By applying pressure, the liquid is forced through the membrane, leaving behind larger particles and allowing only smaller molecules to pass through. This allows for the separation and purification of substances based on their size and solubility.

5.

The sodium pump which pumps excess sodium out of the cell into extracellular fluid is an example of _______________________ _________________________.

Explanation
The sodium pump is an example of active transport because it requires the use of energy to move sodium ions against their concentration gradient from inside the cell to the extracellular fluid. This process is essential for maintaining the proper balance of sodium ions inside and outside the cell, as well as for generating the electrical potential across the cell membrane.
