Can you guess the correct number of amino acids that are responsible for making up a single protein?
Twenty amino acids make a single protein. Out of the twenty amino acids, 11 are essential amino acids, whereas 9 are non-essential ones. Essential amino acids cannot be created in our body, they are obtained from food. Whereas non-essential amino acids are synthesized or produced by our body.
Which of the following food products listed below are high in proteins?
Lentils and grains, egg and tofu, and all dairy products are rich sources of proteins. So, the correct answer to the question is all the above options.
Out of the functions listed below, one of them is NOT the function of the protein. Which one function, protein is not responsible for?
From the above options, that are listed, carrying genetic information is NOT the function of proteins.
Protein deficiency causes a lot of health problems. Which disease is caused by protein deficiency, out of the listed options?
Kwashiorkor disease is caused by protein deficiency. This disease is also called protein malnutrition. Early symptoms are marked by irritability, fatigue, and lethargy. When the disease progresses, it leads to loss of muscle mass, edema, low immunity, and delayed growth.
The bond between the amino acids is known by a specific term. What is it?
The bond that exists betwixt the amino acids is called Peptide Bond. It forms a long chain-like structure.
Name of the process that results in the unfolding of proteins...
The process of unfolding proteins is called Denaturation. The process involves the transition of proteins from the folded to the unfolded state. Denatured proteins are the ones that have lost their 3D structure and therefore cannot perform their assigned functions.
Out of the four options listed below, which one is the fibrous protein?
Out of the options listed above, Collagen is the correct answer. It is a fibrous protein present in blood vessels, cartilage, bones, and other parts of the body. Collagen accounts for thirty percent of the total protein present in the human body.
Can you name the protein present in the wheat grain?
The protein that is present in wheat grain is glutenin. Other than Glutenin, Gliadin is also present in wheat flour. Together these two proteins comprise about eighty percent of the total proteins in the wheat flour.
One of the significant functions of protein is to prevent blood loss after an injury. What is the process of preventing blood loss called?
The process of preventing blood loss after an injury is called blood clotting or Coagulation. The proteins and the platelets present in the blood plasma work hand in hand to stop blood loss after an injury.
Frederick Sanger was the person who was responsible for sequencing the first protein. Which protein was it?
Fredrick Sanger was a biochemist who was responsible for sequencing Insulin. He was the first person who was successful in obtaining a protein sequence. He was additionally awarded The Nobel Prize in 1958 for this commendable work.
Out of the listed options, one option is an example of defense proteins. Which is the one?
Immunoglobulin is a defense protein. Defense proteins are antibodies that are produced by the body to fight against diseases and for the prevention of injury. It binds to the foreign proteins and helps in neutralizing them.
Which process determines the 3-D structure of the proteins?
Both options A and B, X-Ray Crystallography and NMR (Nuclear Magnetic Resonance procedures are used to determine the protein structure. NMR is suitable only for small proteins that have less than one hundred and fifty amino acids.
What are enzymes?
As biological catalysts, enzymes play an important role in living organisms. The biological process taking place in living organisms are chemical reactions, that are regulated by enzymes.
What is the daily protein requirement in an adult man?
Daily protein requirement varies in an adult man and an adult woman. An adult man needs 56 grams of protein in a day. Female requirement of daily protein is less than that of a man. An adult woman requires 46 grams of protein on daily basis. However, it varies in the case of a pregnant woman.
How many amino acids does the human body use to build proteins?
Twenty amino acids constitute the proteins found in the human body. Though, there are 500 amino acids identified in nature. Out of the 20 amino acids, nine are essential amino acids and eleven are non-essential amino acids.
Certain food items are considered the source of complete proteins. Out of the given list of options which is the source of complete proteins?
Out of the options listed above, meat and fish are the sources of complete proteins. Foods with complete proteins are the ones that have all the nine essential amino acid presents in them. Plant-based protein food sources lack one or more essential amino acids. Therefore, it cannot be considered a source of complete protein.
How many structures are proteins divided into?
Protein structure is divided into four types- primary, secondary, tertiary, and quaternary structures. The division of structure of the protein depends on the level of its complexity.
Which is the simplest amino acid?
Glycine is the simplest amino acid. It is most commonly found in animal proteins. It plays a crucial role in creating several other Proteins and important bio-compounds. It is considered the simplest amino acid as it just has a single hydrogen atom as a part of its side chain.
Which factor is responsible for determining the 3D structure of a protein?
The sequence of the amino acids determines the unique three-dimensional shape of the protein. The primary structure or the order of the amino acids determines the folding pattern of the chain of amino acids, which in turn decides the folding pattern of the protein. The shape of the protein is very important as it determines its functions.
Out of the listed options, which disorder is caused due to protein deficiency?
Protein deficiency in the human body leads to loss of muscle mass. It not only causes general fatigue but also results in weight loss. It also slows down the metabolic rate. It can also cause anemia. As a result of which cells fail to get the required oxygen leading to fatigue and low stamina.
