Multiple choice evs deficiency diseases need for nutrients nutrients needed by the body balanced diet and malnutrition food for health nutrition and its deficiency nutrition and its need

Which one includes others?

  1. Photosynthesis

  2. Catabolism

  3. Metabolism

  4. Anabolism
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Photosynthesis is a metabolic process of formation of glucose from carbon dioxide and water in presence of light energy.

Anabolic processes are those in which small molecules combine to form large molecules. The photosynthesis is an anabolic process as small carbon and hydrogen molecule combine to form the glucose.
Catabolism is a process of breakdown of larger molecules into smaller once. The photolysis of water is a catabolic process.
So, the correct option is 'Photosynthesis'

Reduced coenzyme NADPH $(H^+)$ is produced in respiration during

  1. Glycolysis

  2. PPP

  3. Krebs cycle

  4. Terminal oxidation.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

PPP or pentose phosphate pathway is an important pathway that takes place in the cytoplasm.

 It is an alternative path for the Krebs cycle and is the only pathway that forms reduced NADH. The enzyme transhydrogenase, that transfers the hydrogen of NADPH to NAD and forms NADH.
So, the correct option is 'PPP'

One example of a nutrient in its reduced form is

  1. Carbon in $CO _2$
  2. Hydrogen in $H _2O$
  3. Nitrogen in $NH _3$

  4. Sulphur in sulphate
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In NH3 (ammonia), nitrogen is in the -3 oxidation state, which is its most reduced form. In CO2, carbon is in the +4 state (oxidized); in H2O, hydrogen is in the +1 state; in sulphate, sulphur is in the +6 state.

Which of the following statement is correct for a protective role of photosynthesis?

  1. With the insufficient fund of availability of co2 the light energy cannot be fully absorbed

  2. In c4 plant some of the oxygen is combined with rubisco

  3. Either presence or absence of light, yield and productivity is c4 plant is always high

  4. Excess light can cause photo-oxidation and damage the plant, Photorespiration provides protection against this
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

 A limiting factor is simply anything in short supply that will limit the rate of photosynthesis. Photosynthesis has 3 limiting factors: light intensity, carbon dioxide concentration, temperature. Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesis if there is insufficient carbon dioxide as the light energy cannot be fully absorbed. 

So, the correct option is 'with the insufficient fund of availibility of co2 the light energy cannot be fully absorbed'.

What is needed in photosynthesis to convert carbon dioxide into organic molecules?

  1. Light and hydrogen from the splitting of water

  2. Light and oxygen from the splitting of water

  3. ATP and hydrogen from the splitting of water

  4. ATP and oxygen from the splitting of water
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The process of photosynthesis in plants involves a series of steps and reactions that use light energy, water, and carbon dioxide to produce oxygen and organic compounds.
 6CO$ _{2}$  + 6H$ _{2}$O + light energy $\longrightarrow$ C$ _{6}$H$ _{12}$O$ _{6}$ + 6O$ _{2}$.

Here, glucose is produced using the Hydrogen, emitted from the splitting of water. Light energy is also required for the reaction to take place.

What does an inorganic compounds contain?

  1. Sodium Chloride

  2. Nutrients

  3. Oil

  4. Fats
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sodium chloride (NaCl) is a classic example of an inorganic compound, as it is an ionic salt lacking carbon-hydrogen bonds. Oil, fats, and nutrients (like proteins/carbohydrates) are organic compounds.

During prolonged fasting, the sequence of organic compounds used by body is 

  1. Carbohydrates, fats, proteins

  2. Fats, carbohydrates, proteins

  3. Carbohydrates, proteins, lipids

  4. Proteins, lipids, carbohydrates
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The body burns fat after first exhausting the contents of the digestive tract along with glycogen (carbohydrates) reserves stored in muscle and liver cells. During short periods of energy abstinence, the human body will burn primarily free fatty acids from body fat stores. After prolonged periods of starvation when the body has depleted its body fat, it begins to burn lean tissue and muscle (protein) as a fuel source.

The radiant energy is stored in the form of chemical energy in

  1. DNA

  2. stored food

  3. RNA

  4. ATP
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released. Chemical Energy - is really a form of potential energy and is the energy stored in food or chemical combinations. Radiant Energy - is a combination of heat and light energy.

So, the correct option is 'stored food'.

Best source for dietary protein for a vegetarian is

  1. Soya Bean

  2. Gram

  3. Groundnut

  4. Milk
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • A vegetarian diet can be a healthy option for many reasons. When choosing vegetarian foods, consider the different ways to get the nutrients you need, including vegetarian protein sources. 
  • For those looking for meatless protein sources, especially lacto-vegetarians whose diets do not include eggs. Milk and milk products are a great choice because milk is a good source of high-quality protein. Hence, the best source for dietary protein for a vegetarian is milk.
So, the correct answer is 'milk'.
