  2. Soyabean and Til

  3. Moong and Ragi

  4. Sprouted pulses and cod liver oil

  5. All of the above

Show answer
Correct Option: E
Explanation:

The nitrogenous compound in our diet is a protein which is made up of various amino acids containing the amino group. These are found in the nodulated plants that mostly belongs to family Fabaceae includes all types of pulses, soybean, til.

ragi is used as cereal mainly contains carbohydrates but protein and fibers are also present in moderate amount.

  1. activator

  2. repressors

  3. necessary proteins

  4. accessory proteins

Show answer
Correct Option: A
Explanation:

The activator proteins bind to the operator site on the m-RNA to start the process of transcription. This is called as positive regulation since it starts the transcription process and hence the activator protein is called positively regulatory proteins.

  1. Transport nutrient across cell membrane

  2. Work as enzyme

  3. Work as receptor

  4. Main source of energy

Show answer
Correct Option: D
Explanation:

Proteins are an important component and are the building block of each cell and perform various functions like:

  • Proteins act as the transporter, it transports the minerals and nutrients across the cell membrane, transport oxygen molecule and is responsible for the connection of the two cells.
  • All the enzymes are proteins and they catalyze various reactions and increases the speed of the reaction.
  • Receptors are the proteins that receive some chemical signals and respond according to them. They change their physiology according to the chemical reaction and signals.
  • ATP is the main source of energy, proteins and fats are the nutrients that sometimes help in the production of a small amount of energy.
So, the correct option is 'Main energy source'.

  3. Oxygen

  4. All of these

Show answer
Correct Option: D
Explanation:

Proteins are made up of amino acids. The amino acids are molecules containing amine group (NH$ _2$), carboxylic acid group (COOH), and side chains (R).

High content of Lysine is present in

evs nutritious food minerals and vitamins nutrition and diet role of various nutrients

  1. Wheat

  2. Apple

  3. Maize

  4. Banana

Show answer
Correct Option: A
Explanation:

Lysine is an essential amino acid that helps your body to absorb calcium, burn fat and maintain your skin, tendons, bones and cartilage.
