Which of the following is a major growth-limiting micronutrient that influences microbial growth?
A) iron
B) transferrin
C) lactoferrin
D) sugar

Question

Quizplus · Accepted Answer

Iron is a major growth-limiting micronutrient that influences microbial growth. It is an important component of many enzymes that are involved in cellular processes such as respiration, DNA synthesis, and metabolism. Iron is often present in limited quantities in the environment, so its availability can be a critical factor for microbial growth. While transferrin and lactoferrin can bind to iron and transport it in the body, they are not growth-limiting factors for microbial growth. Sugar is a source of carbon and energy, not a major growth-limiting micronutrient that influences microbial growth.
