Answer:

(3) synthesis of protein

Explanation:

Ribosomes are protein synthesis factories. Once mRNA has been transcribed from DNA in the nucleus, it travels to the cytoplasm where it meets ribosomes.

Here, it dictates the order of amino acids to be added in a chain. The ribosome catalyzes the joining of amino acids via a peptide bond. The amino acids are brought in the correct order by tRNAs that are complementary to the mRNA sequence.

The amino acids in the polypeptide chain are folded and modified to form proteins.

____________ is the process by which inhibitory transmitters cause the inside of the neuron to become more negative.
lidiya [134]

Answer:

Hyperpolarization

Explanation:

At the synapse, neurotransmitters bind to neurotransmitter receptors in the postsynaptic neuron’s plasma membrane. This results in the opening of the ions channels and the flow of specific ions to change the voltage across the membrane. An inhibitory neurotransmitter inhibits the firing of the action potential by making the inside of the membrane more negative. It is called hyperpolarization (inhibition).

It may occur when the neurotransmitter opens the Cl– or K+ channels to allow the movement of chloride ions into the cell while permitting the outward movement of potassium ions to make the inside of the cell more negative.

Hexokinase is an enzyme that is involved with glycolysis (the breakdown of glucose for energy release) that occurs in the cytopl
Murrr4er [49]

Answer:

Free Ribosomes

Explanation:

This is produced by the free ribosomes in the Cystosol ( thst is  bounded by membrane,not attached to the endoplasmic reticulum), They are concerned with the synthesis of  proteins to be used within the cystosol  that is not to be exported out of the cells.

Hexokinase produced is important in glycolysis because it phosphorylated glucose to glucose -6-phosphate, increases its polarity  thus reduced the  metabolic process within the cell   preventing glucose  from leaving the cell( due to increase polarity which is restricted by the cell ,membrane.) thereby increasing the efficiency of process of Glycolysis.
