Answer:
b.Movement of phospholipids in the plasma membrane from one monolayer to the other requires the polar or charged head groupd to enter the hydrophobic interior of the lipid bilayer. This process requires a large positive change in free-energy, thus making this type of movement unlikely without an input of energy
The plasma membrane serves a protective function for the cell and is a selective membrane for particles entry

Answer:
The correct answer is option (a) "Increase the amount of neurotransmitters secreted".
Explanation:
Presynaptic neurons are helpful cells at chemical synapsis because they increase the intensity of the transmitted signals by increasing the amount of neurotransmitters secreted. The neurotransmitters are the carriers of information from the pre-synaptic—sending—neuron to the post-synaptic—receiving—cell, which results in an action potential.
