This set of Biochemical Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Biological Basics – Micronutrients and Macronutrients”.
1. What is the amount of micronutrients required for humans on daily basis?
a) >150mg/day
b) <150mg/day
c) <100mg/day
d) <50mg/day
View Answer
Explanation: The requirement of micronutrients for human is less than 100mg/day. At the same time, macronutrients are required in large quantities.
2. Minerals which cannot be synthesized in the human and animal body are obtained from Earth’s soil. What is the total number of minerals obtained from the soil?
a) 10
b) 11
c) 12
d) 13
View Answer
Explanation: There are 13 elements found from the Earth’s soil. These elements are not synthesized by the living organisms for example: – Calcium, Iron.
3. Which vitamin was found to be deficient in developing countries at the 1990 World Summit for Children?
a) Vitamin A
b) Vitamin B1
c) Vitamin B12
d) Vitamin K
View Answer
Explanation: The micronutrient which was found to be deficient at the 1990 World Summit of Children is Vitamin A. Two macronutrients were also found to be deficient they are Iodine and Iron.
4. Which micronutrient is required to increase the crop yield?
a) Zn
b) Ca
c) K
d) Li
View Answer
Explanation: Zinc deficiency was overcome by the addition of Zinc Fertilizers. These fertilizers helped in the increase of crop yield, balanced the nutrition levels by providing zinc at a cost effective manner.
5. Which of this micronutrient play an important role during osmotic regulation?
a) Boron
b) Chlorine
c) Copper
d) Iron
View Answer
Explanation: Chlorine is used to maintain an osmotic and ionic balance. It also plays an important role during photosynthesis.
6. Which of this micronutrient is required to activate the enzymes required for Chlorophyll production?
a) Molybdenum
b) Copper
c) Iron
d) Manganese
View Answer
Explanation: Manganese activates the enzymes for chlorophyll formation. The plants which are deficient of manganese will exhibit chlorosis.
7. The availability of Manganese depends on ______
a) Temperature
b) Moisture content
c) pH
d) Water level
View Answer
Explanation: Manganese availability is partially dependent on the pH of the soil. The manganese deficient plants will develop chlorosis.
8. Which of these is a not a macronutrient?
a) Glycine
b) Capric acid
c) Fructose
d) Iron
View Answer
Explanation: Iron is a micronutrient which is very minutely required in the human body. The others are macronutrients which are required in a very large amount, even more than the threshold amount.
9. Which of these is a major component of Starch?
a) Amylopectin
b) Amylose
c) Glucose
d) Fructose
View Answer
Explanation: Amylose is the major component present in starch. Amylose and Amylopectin are the monomers of Starch which are linked together using glycosidic bonds.
10. Which of these fatty acids are starters of omega acid production?
a) α-Linolenic acid
b) Cervonic acid
c) Arachidonic acid
d) Timnodonic acid
View Answer
Explanation: α-Linolenic acid is an essential fatty acid which cannot be synthesized within the human body. It is an omega 3-ftty acid found in vegetable oils and nuts.
11. Water is a micronutrient.
a) True
b) False
View Answer
Explanation: Water is a macronutrient which is required for almost 75% in the human body. It is necessary for the absorption of other macromolecules and it does not provide any nutritional value.
12. Which of these are conditionally essential nutrients?
a) Potassium
b) Magnesium
c) Choline
d) Cobalt
View Answer
Explanation: These nutrients are usually synthesized by the organisms itself but under some conditions they become insufficient. The reduction in this nutrients lead to limited nutrient uptake, premature birth and etc.
13. What is the amount of Vitamin C required on daily basis in India?
a) 60mg/day
b) 50mg/day
c) 45mg/day
d) 40mg/day
View Answer
Explanation: The amount of vitamin C required in India for one day is 40mg/day. Whereas, it is required in an amount of 155mg/day for the EU.
14. Which of these amino acid cannot be endogenously synthesized within a human body?
a) Valine
b) Alanine
c) Glycine
d) Serine
View Answer
Explanation: Valine cannot be synthesized within a human body. The other eight amino acids which cannot be synthesized are Leucine, Isoleucine, Phenylalanine, Threonine, Tryptophan, Methionine, Lysine and Histidine.
15. Which of these elements are essential for chlorophyll synthesis?
a) Zinc
b) Molybdenum
c) Manganese
d) Iron
View Answer
Explanation: Molybdenum is required for the maintenance of plant health. Molybdenum reduces nitrates into usable forms of nitrites.
