Protein forms part of the structure of A - VCE - SSCE Biology - Question 8 - 2012 - Paper 1
Question 8
Protein forms part of the structure of A. polysaccharides. B. transfer RNA. C. phospholipids. D. haemoglobin.
Worked Solution & Example Answer:Protein forms part of the structure of A - VCE - SSCE Biology - Question 8 - 2012 - Paper 1
Step 1
Identify the correct option
Answer
To determine which option protein forms part of the structure, we need to analyze each choice:
- A. Polysaccharides: These are carbohydrates, primarily made up of sugar molecules. Proteins do not form part of their structure.
- B. Transfer RNA: tRNA is a type of RNA molecule that helps in protein synthesis, but it is not a protein itself, although it works with proteins.
- C. Phospholipids: These are lipid molecules but may interact with proteins in cellular membranes; proteins do not form part of their structure.
- D. Haemoglobin: This is a protein in red blood cells that is crucial for transporting oxygen. Thus, proteins are integral to its structure.
The correct answer is D. haemoglobin.
