Answer:
A, These proteins are created in the body by condensation of amino acids under the influence of enzyme catalysts, using patterns or direction from the nucleic acids in the cells. The amino acid units in a protein molecule are held together by peptide bonds, and form chains called polypeptide chains.

Out of the four given statements, the false statement is
option d)
Explanation:

c) Na+ and Cl- are the major content of extracellular fluids
d) About 60% of water inside the body is contained within extracellular and not in intra cellular.
Answer: a. too much acetylcholine staying in the neuromuscular junction for too long
Explanation:
Sarin is a gaseous organophosphate. This gas is used for chemical warfare. This affects the nervous system of the body. The gas if inhaled can cause death within minutes.
Acetylcholine is a neurotransmitter molecule. It is released from the pre-synaptic neurons that binds to the acetylcholine receptors.
The gas sarin will target the enzyme acetylcholinesterase present in the neuromuscular junction of the body where the nerves actually meet the muscles. The enzyme degrades nerve signaling molecule acetylcholine. Thus when the sarin degrades the enzyme the levels of acetylcholine will rise up in the blood. The acetylcholine remain in the neuromuscular junction. The acetylcholine will stimulate the nerve cell receptors. Excess of acetylcholine will cause excessive twitching and may lead to paralysis.
