Select the INCORRECT statement with regards to vitamins.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Some bacteria in the gut do not produce vitamins.
In reality, bacteria in the gut play a crucial role in synthesizing certain vitamins, such as vitamin K and some B vitamins, through processes like fermentation. These synthesized vitamins contribute to the overall nutritional status of the host organism. Therefore, it is inaccurate to claim that some gut bacteria do not produce vitamins, as they indeed play a significant role in vitamin production.
