Question

Enzyme present in saliva is
A)Maltase
B)Ptyalin
C)Sucrase
D)Invertase

Answer 1

The biochemical reactions happening inside the body are catalysed by means of globular proteins known as enzymes. They solely act with the aid of catalysing the chemical response and do no longer bear any changes themselves. A particular reaction and substrate have a unique enzyme. The enzymes are named primarily based on the response or compound they take part in. Enzymes are often termed as biocatalysts.

Complete answer:
Saliva is a watery, extracellular fluid secreted by means of the salivary glands on stimulation via each the sympathetic frightened system and parasympathetic fearful system.
Saliva includes 98 percentage water and many essential elements such as mucus, immunoglobulins, mucins, white blood cells, epithelial cells, proteins, enzymes such as amylase and lipase, electrolytes such as potassium, calcium, phosphate, magnesium, sodium, and bicarbonates, nitrogenous merchandise such as ammonia and urea, and antimicrobial marketers such as lysozymes.

The saliva is related with a number of physique functions. Saliva promotes thorough chewing of food, softening of meals particles to ease swallowing, cleansing the mouth, chemical digestion, presents lubrication, and protects the oral mucosa from drying. The salivary amylase enzyme breaks down starch into dextrin and maltose. This allows the digestion of meals in the mouth. These enzymes also ruin down food particles embedded in the dental crevices, as a consequence preventing dental bacterial decay.

Now let us find solution from given options:
Maltase: Maltase is an enzyme that acts as a catalyst in the hydrolysis process of maltose. Wherein maltose breaks down into simpler sugar glucose. This enzyme is located in yeast, microorganism and plants. In the human body, it is existing in the small gut facilitating the breakdown of disaccharide maltose into easier sugar molecules.
Ptyalin: Ptyalin is additionally known as salivary amylase. It is produced and secreted by way of the salivary glands facilitating the digestion of meals in the mouth even earlier than it reaches the stomach.
Sucrase: Sucrase is a digestive enzyme. It participates in the hydrolysis response of sucrose. Sucrose hydrolysis into its subunits glucose and fructose.
Invertase: Invertase is a sucrose enzyme which regularly happens in plants. It helps breakdown sucrose into glucose and fructose.

Hence, the correct answer is option (B)

Note: Sometime overproduction of saliva ought to occur. This should appear due to niacin or diet B3 deficiency, rabies, gastroesophageal reflux disease, etc. Other factors that should facilitate the overproduction of saliva encompass pregnancy, liver disease, oral ulcers, oral infections, pancreatitis, etc. Some medicines should additionally result in overproduction of saliva such as pilocarpine, ketamine, clozapine, and potassium chlorate.
