The function of vitamin K in human body isA. clotting of blood.B. oxidation of glucose.C. absorption of calcium.D. synthesis of eye pigments

Breakdown of the Problem

1. Identify the function of vitamin K.
2. Analyze the options provided to determine which one correctly describes the role of vitamin K.

Relevant Concepts

Vitamin K is primarily known for its essential role in the blood coagulation (clotting) process. It helps in the synthesis of proteins that regulate blood clotting, as well as proteins that are involved in bone metabolism and the regulation of blood calcium levels.

Analysis and Detail

1. Option A: Clotting of blood - This is the primary and most well-known function of vitamin K. It activates proteins that are essential for blood clotting.
2. Option B: Oxidation of glucose - This is more related to energy metabolism and does not pertain to vitamin K.
3. Option C: Absorption of calcium - While vitamin K does play a role in bone metabolism, its direct function is more related to calcium regulation in bone rather than absorption.
4. Option D: Synthesis of eye pigments - This is not related to vitamin K.

Verify and Summarize

Based on the analysis, the most accurate answer reflecting the function of vitamin K is the one relating to blood clotting.

Final Answer

A. clotting of blood.
