Protein | MCQs

Explanation

The correct order is: Ribosomes → RER → Golgi body → Lysosome.

• Ribosomes: Protein synthesis occurs here, and the newly synthesized protein is released into the cytosol.
• RER (Rough Endoplasmic Reticulum): The protein is transported to the RER, where it is processed and modified (e.g., folding, glycosylation).
• Golgi body: The protein is packaged into vesicles and transported to the Golgi body, where it is further modified and sorted.
• Lysosome: The protein is delivered to lysosomes, where it can be used for various cellular processes (e.g., digestion, recycling).

Explanation

• The rough endoplasmic reticulum (RER) is responsible for synthesizing proteins, which are then transported to other parts of the cell or secreted outside.
• The RER has ribosomes attached to its surface, where protein synthesis occurs.

Explanation

Vegetable products (breads, cereals, rice, pasta, dried beans) are considered "low quality protein."

Explanation

Chromosomes are made up of:

• Nucleic acid (DNA or RNA)
• Proteins (histones and non-histone proteins)

Explanation

The amount of protein for a healthy child aged 7-14 is approximately:

• 1g per kilogram of body weight for children with minimal activity
• 1.3g per kilogram of body weight for children completing moderate levels of exercise
• 1.6g per kilogram of body weight for children carrying out intense exercise

Explanation

• Peanuts are a legume and a good source of protein, containing about 20.5 grams of protein per 100 grams.
• Apples: 0.3 grams of protein per medium-sized fruit
• Watermelon: 0.6 grams of protein per cup
• Mango: 1.4 grams of protein per cup

Explanation

• Apples contain about 0.3 grams of protein medium-sized fruit.
• Watermelon: 0.6 grams of protein per cup.
• Mango: 1.4 grams of protein per cup.
• Peanuts: 20.5 grams of protein per 100 grams.

Explanation

Milk, meat, eggs, and pulses are all rich sources of Protein, which is essential for:

• Building and repairing tissues
• Producing enzymes and hormones
• Maintaining healthy muscles, bones, and organs

Explanation

• Carbohydrates are the body's primary source of instant energy.
• They are broken down into glucose.
• Which is absorbed into the bloodstream and transported to cells throughout the body.
• Where it is converted into energy.
