Worked Solution & Example Answer:The site of synthesis of protein M is the A - VCE - SSCE Biology - Question 6 - 2013 - Paper 1
Step 1
The site of synthesis of protein M is the
Answer
The synthesis of proteins typically occurs at ribosomes, which can be found in two locations: free in the cytoplasm and bound to the endoplasmic reticulum, specifically the rough endoplasmic reticulum. Since ribosomes are responsible for translating mRNA into polypeptides (proteins), and given that protein M is made by a particular cell type to be released for use by other cells, the correct answer is clearly:
B. ribosomes.
