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.

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

  1. Growth hormone

  2. TSH

  3. Oxytocin

  4. FSH

A Correct answer
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.

  1. Spinal fluid

  2. Blood

  3. Cell

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
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 

  1. Biogenic amines

  2. Proteins, steroids and biogenic amines

  3. Proteins only

  4. Steroids only
Reveal answer Fill a bubble to check yourself
B Correct answer
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

  1. Prothoracic gland

  2. Corpora allata

  3. Corpora cardiaca

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
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.
