Q: Which of the following amino acids is essential in the human diet?
Solution: Lysine is an essential amino acid that must be obtained through the diet, while glycine, alanine, and serine can be synthesized by the body.
Steps: 5
Step 1: Understand what amino acids are. They are the building blocks of proteins.
Step 2: Learn the difference between essential and non-essential amino acids. Essential amino acids cannot be made by the body and must be obtained from food.
Step 3: Identify the amino acids listed in the question: lysine, glycine, alanine, and serine.
Step 4: Check which of these amino acids are essential. Lysine is essential, while glycine, alanine, and serine are non-essential because the body can make them.
Step 5: Conclude that lysine is the only essential amino acid in the list.
