Answer:
d. more permeable to sodium ions.
Explanation:
The binding of Acetylcholine with the receptors at motor end plate facilitate membrane permeability to sodium ions therefore opening of voltage gated channels for sodium ions.
Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.
If the stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the synapse to depolarize the membrane with reversal of charges to generate action potential.
The continuous binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization. Acetycholinesterase enzymes breakdown Acetycholine to choline and Acetyl Co -A. These are recycle back to Acetycholiine

a d*ck and a yk what-
Explanation:
no need for me to say more,
Answer:
Golgi apparatus
Explanation:
Once the protein products are packaged in the endoplasmic reticulum into vesicles that fuse to the Golgi apparatus, these protein products are modified by enzymes. These changes are called post-translational modifications and include the addition of carbohydrates, lipids or some other functional groups. All these modifications are key for protein functionality. After this process is concluded, functional proteins are packaged into vesicles and released to their final destination inside or outside the cell.
