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'.

The ultimate source of energy in human beings is

  1. Fats

  2. Carbohydrates

  3. Proteins

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fats are broken down into free fatty acids (FFA) and triglycerides which can produce ATP through chemical reactions.

Fatty acids either circulate in the blood or are stored as triglycerides in adipose tissue and muscle.
Fat is a very energy dense nutrient, one gram of it provides nine calories of energy. 
Despite the large quantity of available energy that fat has it provides this energy at a much slower rate than carbohydrate. This is because the chemical reactions required for its breakdown are much more complex and time consuming.

Which of the following has the highest calories per gram?

  1. Proteins

  2. Fats

  3. Sugar

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

Calories are needed to provide energy so the body functions properly. The number of calories in a food depends on the amount of energy the food provides. The number of calories a person needs depends on age, height, weight, gender, and activity level. People who consume more calories than they burn off in normal daily activity or during exercise are more likely to be overweight.

The amount of energy one will get from carbohydrate, protein and fat is measured in calories per gram. Fats have the most energy and proteins have the same amount as carbohydrates, but their value as a source of energy is determined by more than the calories gained from one gram.
Fat: 1 gram = 9 calories 
Protein: 1 gram = 4 calories 
Carbohydrates: 1 gram = 4 calories

Therefore, the correct answer is option B.

Saturated fat is

  1. Solid at room temperature

  2. Has fatty acids with no double bonds between the carbon atoms

  3. Is of animal origin.

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Saturated fats are simply fat molecules that have no double bonds between carbon molecules because they are saturated with hydrogen molecules. These are typically solid at room temperature and are found in animals.

So the correct option is 'All of the above'.

Which compound produces more than twice the amount of energy as compared to carbohydrates?

  1. Protein

  2. Fats

  3. Vitamins

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

Carbohydrates are the primary fuel used in cellular metabolism. Excess carbohydrates are stored as glycogen and fats. The fats are a very concentrated source of energy. One gram of fat provides 8.8 kcal of energy as against 4.2 kcal provided by one gram of carbohydrate.
