A Correct answer
Explanation

Antidiabetic drugs are medicines developed to stabilise and control blood glucose levels amongst people with diabetes. Antidiabetic drugs are commonly used to manage diabetes.

There are a number of different types of antidiabetic drug including:

  • Insulin
  • Pramlintide (Amylin)
  • $GLP-1$ receptor agonists (such as Byetta and Victoza)
  • Oral hypoglycemics (tablets)

The function(s) of oxytocin is/are to :

  1. stimulate the release of milk from the mother's mammary glands when her baby is nursing.

  2. cause the uterus to contract

  3. induce labor

  4. all of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Functions of oxytocin are: 
(i) It helps uterine muscles to contract and also increases production of prostaglandins
(ii) Sometimes it is given to induce labor if it has not started naturally or it can be used to strengthen contractions to aid childbirth.
(iii) Stimulate the release of milk from the mother's mammary glands.

The hormone which  transport glucose from blood tissue is

  1. glucogen

  2. insulin

  3. throxin

  4. heparin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Insulin is the hormone responsible for transporting glucose from blood into tissues by promoting glucose uptake in cells, particularly muscle and adipose tissue. It lowers blood glucose levels by facilitating glucose entry into cells. Glucagon has the opposite effect of raising blood glucose.

The enzyme that is not associated in the preparation of $C _{2}H _{5}OH$ from starch is:

  1. maltase

  2. diastase

  3. invertase

  4. zymase
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Starch is hydrolyzed to Maltose by an enzyme called diastase
Maltase converts Maltose to Glucose
Zymase converts Glucose to ethanol.
So the enzyme that is not associated in the preparation of ${C} _{2}{H} _{5}OH$ from starch is invertase

Coenzyme is :

  1. the non-protein component of an enzyme which is loosely held by the enzyme and necessary for its biological activity

  2. the protein component of an enzyme which is loosely held by the enzyme and necessary for its biological activity

  3. the non-protein or protein component of an enzyme which is loosely held by the enzyme and necessary for its biological activity

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A coenzyme is an organic non-protein compound that binds with an enzyme to catalyze a reaction. A coenzyme cannot function alone, but can be reused several times when paired with an enzyme. Without coenzymes or cofactors, enzymes cannot catalyze reactions effectively.

The reaction of water with slaked lime is studied by ________ .

  1. putting slaked lime into water taken in a test tube

  2. putting a lot of water into slaked lime.

  3. sprinkling a little water on slaked lime.

  4. none of the above method.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The reaction of water with calcium oxide (quicklime) to form slaked lime is highly exothermic. To study it safely, one typically adds small amounts of water to the lime or vice-versa under controlled conditions, but the standard laboratory demonstration involves adding water to the solid.

$A \, Ca(HCO _3) _2 + B \, Ca(OH) _2 \to C \, CaCO _3 + D \, H _2O$. 


Choose the correct option.

  1. $A = 1$
  2. $B = 1$
  3. $C = 1$
  4. $D = 2$
Reveal answer Fill a bubble to check yourself
A,B,D Correct answer
Explanation

$ACa(HCO _3) _2 + BCa(OH) _2 \rightarrow CCaCO _3 + DH _2O$

First, balance calcium then oxygen ,then hydrogen.

$Ca(HCO _3) _2 + Ca(OH) _2 \rightarrow 2CaCO _3 + 2H _2O$
                       (This the balanced equation)
