  1. Insulin

  2. Penicillin

  3. Chloroquine

  4. Aspirin

Show answer
Correct Option: A
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)

  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

Show answer
Correct Option: D
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

Correct Option: B

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

chemistry biochemistry enzymes and hormones hormones coordination in human beings- chemical control

  1. maltase

  2. diastase

  3. invertase

  4. zymase

Show answer
Correct Option: C
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 :

chemistry biochemistry enzymes and hormones hormones coordination in human beings- chemical control

  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

Show answer
Correct Option: A
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.

Pick out the one which does not belong to the family of enzymes.

chemistry biochemistry enzymes and hormones hormones coordination in human beings- chemical control

  1. Lipase

  2. Pepsin

  3. Ptylin

  4. Cellulose

Show answer
Correct Option: D
Explanation:

Cellulose is the carbohydrate which is not considered as enzyme.
Hence option D is correct.
