Consider the following statements regarding Vitamin K: It isa fat-solu...
Vitamin K
Statement 1: It is a fat-soluble vitamin that is not found naturally in the human body.
This statement is incorrect. Vitamin K is a fat-soluble vitamin that is found naturally in the human body. It is produced by certain bacteria in the intestines and can also be obtained through dietary sources. The primary dietary sources of vitamin K include leafy green vegetables, broccoli, Brussels sprouts, and certain vegetable oils. Vitamin K is essential for various biological processes in the body, including blood clotting and bone metabolism.
Statement 2: It helps to make various proteins that are needed for blood clotting and the building of bones.
This statement is correct. Vitamin K plays a crucial role in blood clotting and bone metabolism. In blood clotting, vitamin K is required for the production of several proteins known as clotting factors. These clotting factors help in the formation of blood clots, which are essential in preventing excessive bleeding. Without sufficient vitamin K, the blood clotting process would be impaired, leading to increased bleeding tendencies.
In bone metabolism, vitamin K is involved in the synthesis of osteocalcin, a protein that regulates the mineralization of bone tissue. Osteocalcin helps to bind calcium ions to the bone matrix, contributing to the strength and density of bones. Adequate vitamin K levels are necessary for maintaining optimal bone health and preventing conditions like osteoporosis.
Conclusion:
In conclusion, statement 1 is incorrect as vitamin K is found naturally in the human body, and statement 2 is correct as vitamin K is involved in the production of proteins required for blood clotting and bone building. Therefore, the correct answer is option B.

Consider the following statements regarding Vitamin K: It isa fat-solu...
According to a recent study published, patients with low levels of vitamin K in their blood are more likely to have reduced lung function and suffer from asthma, Chronic Obstructive Pulmonary Disease (COPD), and wheezing.
About Chronic Obstructive Pulmonary Disease (COPD):
- COPD is a common lung disease causing restricted airflow and breathing problems.
- There are two main forms of COPD:
- Chronic bronchitis, which involves a long-term cough with mucus.
- Emphysema, which involves damage to the lungs over time.
- Most people with COPD have a combination of both conditions.
- Causes: It's typically caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke.
- Signs and symptoms:
- The most common symptoms of COPD are difficulty breathing, chronic cough (sometimes with phlegm) and feeling tired.
- COPD symptoms can get worse quickly. These are called flare-ups. These usually last for a few days and often require additional medicine.
- People with COPD are at increased risk of developing heart disease, lung cancer and a variety of other conditions.
- Treatment:
- COPD isn’t curable, but it can get better by not smoking, avoiding air pollution and getting vaccines.
- It can be treated with medicines, oxygen and pulmonary rehabilitation.
Key Facts about Vitamin K:
- It is a fat-soluble vitamin that comes in two forms.
- The main type is called phylloquinone, found in green leafy vegetables like collard greens, kale, and spinach.
- The other type, menaquinones, is found in some animal foods and fermented foods. Menaquinones can also be produced by bacteria in the human body.
- Vitamin K helps to make various proteins that are needed for blood clotting and the building of bones.
- Vitamin K is found throughout the body, including the liver, brain, heart, pancreas, and bone.
- It is broken down very quickly and excreted in urine or stool. Because of this, it rarely reaches toxic levels in the body even with high intakes, as may sometimes occur with other fat-soluble vitamins.
Hence only statement 2 is correct.
