Daily Current Affairs MCQ- May 11, 2024 - Question 1

Consider the following statements with reference to Maillard Reaction:

1. It is a chemical process that occurs when amino acids and sugars are heated.

2. It depends on acidity and moisture content of the food.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQ- May 11, 2024 - Question 1

Maillard Reaction explains about complex chemical mechanism regarding flavours, aromas, and textures of foods. 

  • It was named after the early 20th-century French scientist Louis-Camille Maillard.
  • The Maillard reaction is a chemical process that occurs when amino acids, which are the building blocks of proteins, and sugars are heated. The process affects the flavours, aromas and textures of foods. 
  • This reaction is a form of non-enzymatic browning of food, which means that the colour change occurs without the activity of enzymes. 

How does the Maillard reaction cause browning of food? 

  • It is a complex chemical mechanism that leads to the formation of multiple products through the process. Chemist J.E. Hodge in 1953 was the first to break down the reaction into steps for simplification. 
  • A variety of foods, including meats, bread, vegetables, coffee beans etc., contain both sugars and protein units.
  • When food is heated, these sugars and proteins undergo a condensation reaction to form a protein-sugar compound called unstable Schiff base. 
  • When the Schiff base is rearranged and dehydrated, various intermediate compounds form. These compounds react further to produce important flavour compounds and contribute to the development of characteristic aromas in the food. 
  • Some of the intermediate compounds undergo a rearrangement, which results in the reorganisation of the atoms in the Schiff base, creating a more stable product. These products are important precursors for melanoidins, which are responsible for the brown coloration of the food. 
  • These compounds undergo further changes like condensation and polymerisation, leading to the formation of melanoidins — nitrogen-containing compounds that give food the distinct brown colour. 
  • Factors affecting the reaction
  • The rate and extent of this reaction depend on several factors, including temperature, acidity, moisture content, and the types and concentrations of proteins and sugars in the food.
  • Ideal Temperature: These are in the range of 110 degrees C and 170 degrees C, and temperatures higher than that can burn the food and render bitter flavours. 
  • Generally, higher temperatures accelerate the reaction while acidic conditions and the presence of water can inhibit it.
  • This is the reason that foods brown more quickly at higher temperatures and dry foods, such as bread crusts, can develop a deep brown colour during baking. 

Hence both statements are correct.

Detailed Solution for Daily Current Affairs MCQ- May 11, 2024 - Question 2

According to a new study a huge Batagay crater in Siberia's permafrost, is growing by 35 million cubic feet every year as the frozen ground melts.

  • It is also called as "gateway to the underworld," by some locals in Russia's Sakha Republic.
  • Location: It is located in Russia's Far East that forms the world's biggest permafrost crater.
  • It is a crater or megaslump, features a rounded cliff face that was first spotted on satellite images in 1991 after a section of hillside collapsed in the Yana Uplands of northern Yakutia in Russia.
  • Scientists believe that the crater is the result of a melting permafrost land, which was frozen during the Quaternary Ice Age 2.58 million years ago.

What is Permafrost?

  • It is any ground that remains completely frozen—32°F (0°C) or colder—for at least two years straight.
  • Global Distribution
  • These permanently frozen grounds are most common in regions with high mountains and in Earth’s higher latitudes—near the North and South Poles.
  • It covers large regions of the Earth. Almost a quarter of the land area in the Northern Hemisphere has permafrost underneath.

Hence option (d) is the correct answer

Daily Current Affairs MCQ- May 11, 2024 - Question 3

Consider the following statements with reference to the Foot rot disease:

1. It is caused by a soil-seed borne fungus.

2. It primarily affects arecanut plants particularly at the seedling stage.

Which of the statements given above is/are correct?

Detailed Solution for Daily Current Affairs MCQ- May 11, 2024 - Question 3

Recently, Ludhiana’s Punjab Agricultural University has come up with biocontrol agent Trichoderma asperellum to combat ‘foot rot’ disease, prevalent in Basmati rice varieties and registered it with the Central Insecticides Board and Registration Committee (CIBRC).

  • It is a fungal disease that affects Basmati rice crops particularly at the seedling stage.
  • It might also cause infection after transplantation in case infected seedlings are transplanted.
  • It is caused by the fungus Fusarium verticillioides, a soil-seed borne pathogen which spreads the infection through the root of the plant, and eventually leads to the colonisation of the stem base.
  • Infected seedlings first turn pale yellow, then elongate and dry up, and eventually (usually) die.
  • Currently, seedlings are treated with Trichoderma harzianum before sowing and transplantation.
  • Seeds are also treated with fungicides such as Sprint 75 WS (carbendazim + mancozeb) before sowing. But these are the chemical treatments which are harmful for the soil and can be toxic for consumers of the rice.
  • The fungicide carbendazim is already banned in Punjab because it leaves behind high residues.

What is Trichoderma asperellum?

  • It is a biocontrol agent offers a non-chemical alternative to traditional pesticides, aiding in disease management while minimising environmental harm.

Hence only statement 1 is correct.

Which one of the following is the primary cause of Sickle Cell Disease?

Detailed Solution for Daily Current Affairs MCQ- May 11, 2024 - Question 4

Recently, a 12-year-old boy from USA, became the first person in the world with sickle cell disease to begin a commercially approved gene therapy that may cure the condition.

About Sickle Cell Disease (SCD):

  • It is an inherited blood disorder.
  • It is marked by flawed hemoglobin
  • Hemoglobin is the molecule in Red Blood Cells (RBCs) that carries oxygen to the tissues of the body.
  • People with SCD have a typical hemoglobin molecules called hemoglobin S, which can distort RBCs into a sickle, or crescent, shape.
  • SCD interferes with the delivery of oxygen to the tissues.
  • How does it affect blood flow?
  • NormallyRBCs are disc-shaped and flexible enough to move easily through the blood vessels.
  • In SCDRBCs become crescent- or “sickle”-shaped due to a genetic mutation.
  • These sickled RBCs do not bend or move easily and can block blood flow to the rest of the body.
  • What causes it?
  • The cause of SCD is a defective gene, called a sickle cell gene.
  • A person will be born with SCD only if two genes are inheritedone from the mother and one from the father.
  • Symptoms:
  • Early stage: Extreme tiredness or fussiness from anemia, painfully swollen hands and feet, and jaundice.
  • Later stage: Severe pain, anemiaorgan damage, and infections.
  • Treatments:
    • bone marrow transplant (stem cell transplant) can cure SCD.
    • However, there are treatments that can help relieve symptoms, lessen complications, and prolong life.
    • Gene therapy is also being explored as another potential cure.
    • The UK recently became the first country to approve gene therapy treatment for SCD.

Hence option c is the correct answer.
