Osmosis is the diffusion of water across a semi-permeable membrane. The water will move across the membrane where there is a lower concentration of water and a higher concentration of________
-
Air
-
Solute
-
O2
Correct Answer
A. SoluteExplanation
Osmosis sees the movement of water across the membrane where the concentration of water is less and the solute is higher.Rate this question:

- 3.
The process of diffusion is where the particles move from low to high concentration.
-
True
-
False
Correct Answer
A. FalseExplanation
The particles move down the concentration gradient i.e. from high to low concentration.Rate this question:

- 4.
Channel mediated facilitated diffusion is dependent on __________ channels to develop pathways for materials to pass through.
-
Carbohydrate
-
Glucose
-
Protein
Correct Answer
A. ProteinExplanation
Protein channels create pathways for materials to pass through the transportable membrane.Rate this question:

- 5.
The carrier in the mediated facilitated diffusion is known as the transporter.
-
True
-
False
Correct Answer
A. TrueExplanation
Mediated facilitated diffusion is a process in which molecules are transported across the cell membrane with the help of specific carrier proteins. These carrier proteins are known as transporters. They bind to the molecules and facilitate their movement across the membrane. Therefore, the statement "The carrier in the mediated facilitated diffusion is known as the transporter" is true.Rate this question:

Which form of transport sees the movement of substances across the membrane as going against the concentration gradient?
-
Passive
-
Facilitated
-
Secondary Active
-
Active
Correct Answer
A. ActiveExplanation
diffusion is the movement of molecules down a diffusion gradient
Active transport is the movement against a concentration gradientRate this question:

Particles which are free to move across the cell membrane have ________ energy.
-
Partial
-
Free moving
-
Kinetic
-
Kinematic
Correct Answer
A. KineticExplanation
Particles that are free to move across the cell membrane have kinetic energy. Kinetic energy is the energy possessed by an object due to its motion. In the context of particles moving across the cell membrane, kinetic energy refers to the energy associated with their movement. This energy is essential for various cellular processes such as diffusion and active transport. Therefore, the correct answer is "Kinetic."Rate this question:

Which of the following can move through the cell membrane as a means of simple diffusion?
-
Fatty acids
-
O2 and CO2
-
Ions
Correct Answer(s)
A. Fatty acids
A. O2 and CO2Explanation
1. lipid soluble compounds (fatty acids, steroids, alcohols)
2. dissolved gasses (CO2 & O2)
3. absorption of nutrients and excretion of some waste productsRate this question:
