Question

Which of the following is NOT a nutrient in the blood plasma?

• A. Glycine
• B. Creatinine
• C. Fatty acid
• D. Glucose

Hint:

Creatinine is a waste product filtered by the kidneys, while glucose, fatty acids, and amino acids are essential nutrients in the blood plasma.

Answer 1

The Correct Option is B

Step 1: Understanding the blood plasma nutrients.
Blood plasma contains nutrients like glucose, fatty acids, and amino acids (such as glycine). Creatinine, however, is a waste product that is produced from muscle metabolism and is excreted by the kidneys, not a nutrient.
Step 2: Analyzing the options.
(A) Glycine: Incorrect — Glycine is an amino acid, which is a nutrient in the plasma.
(B) Creatinine: Correct — Creatinine is a waste product, not a nutrient.
(C) Fatty acid: Incorrect — Fatty acids are essential nutrients found in plasma.
(D) Glucose: Incorrect — Glucose is an essential energy source in the blood plasma.
Step 3: Conclusion.
The correct answer is (B) Creatinine, as it is not a nutrient in blood plasma.
