  1. Question 1

    Q1. A researcher is studying the biological significance of ethanol in the human body. Which of the following is a major consequence of ethanol's ability to disrupt cellular membrane fluidity?

    • A) Increased permeability of the blood-brain barrier
    • B) Decreased absorption of nutrients from the small intestine
    • C) Enhanced release of neurotransmitters from the pre-synaptic neuron
    • D) Reduced transport of lipids across the plasma membrane

    Answer: Increased permeability of the blood-brain barrier

    Explanation: Ethanol's ability to disrupt cellular membrane fluidity increases the permeability of the blood-brain barrier. The other options describe different effects that are not directly related to membrane fluidity.
