Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Cytochromes are generally membrane-bound hemoproteins that contain heme groups and carry out electron transport. The heme group is a highly conjugated ring system (which means its electrons are very mobile) surrounding a metal ion, which readily interconverts between the oxidation states. For many cytochromes the metal ion present is that of iron, which interconverts between Fe (reduced) and Fe (oxidized) states (electron-transfer processes) or between Fe (reduced) and Fe (formal, oxidized) states (oxidative processes). Cytochromes are thus capable of performing oxidation and reduction.

Essential Mineral Elements
Mineral Elements:
A large number of inorganic elements are necessary for all the life processes and hence should be taken into our diets in adequate amounts. Any deficiency in these minerals leads to an abnormality in the metabolic functioning of the body.
Essential Mineral Elements in Plants
There are two types of minerals that are essential for plant growth, such as:
1. Macrominerals
Minerals like Phosphorous, carbon, silicon, magnesium, hydrogen, sodium, nitrogen, potassium, calcium, oxygen, selenium, and sulfur are required in abundance for proper plant growth and are also found abundantly in plant tissues. Hence, they are known as macrominerals.
2. Microminerals
A few minerals like Iron, boron, zinc, cobalt, chlorine, nickel, manganese, copper, molybdenum, etc. are required in lesser quantities for proper growth by the plants and therefore, they are called microminerals. Further they are also called trace elements.
