Read the following and answer the question based on it. Proteins are used by the body for energy, metabolism, gene growth and maintenance. 10 to 35 percent of the daily calorie intake should ideally consist of proteins. They are found in all cells of the body. Hair and nail are made up of a protein called keratin, having sulphur bonds. Curlier hair has more sulphur links. Too much intake of proteins can sometimes lead to body weight. Proteins _______________
Protein Functions and Daily Needs
Proteins play a crucial role in the body, serving purposes like providing energy, aiding metabolism, and facilitating gene growth and maintenance. They are fundamental components found in all body cells.
Recommended Protein Intake
The text specifies that an ideal daily intake should consist of 10% to 35% of calories from proteins. This recommended range underscores the necessity of consuming adequate quantities of protein for overall health.
Analysis of Choices
- Option 1 Incorrect: The text clearly states proteins are used for energy, metabolism, growth, and maintenance, contradicting this option.
- Option 2 Correct: The functions described and the specific intake percentage (10-35%) strongly indicate that proteins are essential and required by the body in adequate quantities.
- Option 3 Incorrect: While hair contains keratin (a protein), the text doesn't mention proteins affecting hair's shine, length, or color.
- Option 4 Incorrect: The passage explicitly warns that "Too much intake of proteins can sometimes lead to body weight," refuting this claim.

In eukaryotic cells, covalently attached lipids help to anchor some water soluble proteins to the plasma membrane. One group of cytosolic proteins are anchored to the cytosolic face of membrane by a fatty acyl group (e.g. myristate or palmitate). These groups are generally covalently attached to which amino acids present at the N‐terminus of the polypeptide chain?
