Questions Related to hormones

Which of the following is an antidiabetic drug :

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

  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)

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

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

  1. glucogen

  2. insulin

  3. throxin

  4. heparin

Show answer
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.

Which of the following hormones does not have a particular target organ in the body?

biology control and coordination in living organisms hormones coordination in human beings- chemical control endocrine system in humans

  1. Growth hormone

  2. TSH

  3. Oxytocin

  4. FSH

Show answer
Correct Option: A
Explanation:

Growth hormone secreted by the anterior pituitary has a widespread effect in the body. It stimulates growth of various body cells, promotes protein anabolism, absorption of calcium from bowel and conversion of glycogen to glucose.

____________ acts a transporter of hormones in animals.

biology control and coordination in living organisms hormones coordination in human beings- chemical control endocrine system in humans

  1. Spinal fluid

  2. Blood

  3. Cell

  4. All of the above

Show answer
Correct Option: B
Explanation:

  • Blood is the medium of transport of animal hormones. The tissues that produce the hormones are known as the effectors while those tissues that are influenced by the effectors are called targets. Hormones are of low molecular weight and they diffuse readily. 
  • The effects brought about by the hormones are not permanent as they get readily oxidized. 

Therefore, the correct answer is option B.

Chemically hormones are 

biology control and coordination in living organisms hormones coordination in human beings- chemical control endocrine system in humans

  1. Biogenic amines

  2. Proteins, steroids and biogenic amines

  3. Proteins only

  4. Steroids only

Show answer
Correct Option: B
Explanation:

Hormones are a diverse group of biochemicals, which perform a variety of roles in biological systems. Hormones are produced in endocrine glands. Hormones are responsible for maintenance of internal balance and developmental changes in the animal body. 

Chemically, hormones may be peptide (e.g., insulin), amines (e.g., catecholamines), proteins (e.g., growth hormone), steroid hormones (e.g., androgens). 

Ecdysone is secreted by

biology control and coordination in living organisms hormones coordination in human beings- chemical control endocrine system in humans

  1. Prothoracic gland

  2. Corpora allata

  3. Corpora cardiaca

  4. None of the above

Show answer
Correct Option: A
Explanation:

Insects go through a process of moulting during their life cycle. The process is controlled by hormones like moulting hormone and juvenile hormones. Ecdysone is a steroidal prohormone of the major insect molting hormone, which is secreted from the prothoracic glands. Insect molting hormones (ecdysone and its homologues) are generally called as ecdysteroids.
