Questions

Q1. Basal metabolic rate is related to -
Basal metabolic rate is the rate of energy expenditure by human and animal at rest and is measured in kJ per hour per kg body mass.
Q2. Which enzyme does not act on dietary proteins?
Hydrolase is an enzyme that catalyse the hydrolysis of a chemical bond.
Q3. LH is required for -
LH (Luteinising hormone) is secreted by basophil cells of anterior pituitary gland and it is responsible for the complete development of follicle to secretary stage and secretion of oestrogen. In addition it also stimulates the formation of Corpus luteum. In males the LH stimulates the interstitial cells of the testes to secret testosterone.
Q4. which of the following is called as hormone of abundance?
Insulin increases the abundance of growth hormone receptors in liver and adipose tissue. Insulin is also responsible for lipid metabolism, in adipose tissue insulin increases fatty acid synthesis.
Q5. which hormone causes contraction of the gall bladder?
Cholecystokinin is a peptide hormone of Gastrointestinal system, responsible for stimulating the digestion of fat and protein.
Q6. pH of CSF is -
CSF is cerebrospinal fluid. It is clear, slightly alkaline fluid with a specific gravity of 1.005 and pH of 7.33,  consisting of water, mineral salts, glucose, plasma proteins, leukocytes, and small amounts of creatinine and urea.
Q7. Iron is stored in - 
Iron is stored in lever in the form of ferritin in reticuloendothelial (R.E.) cells. The RES (reticuloendothelial system) is responsible for the synthesis of iron from dead cells (RBCs) and storage for the excess of iron.
Q8. Prostaglandin secretion is maximum in -
Semen is a seminal fluid which may contain spermatozoa. It is a major component of male ejaculation. Prostaglandins also secreted with semen on ejaculation in males, in females pristagandins produces during the menstruation and realeased with the menstrual fluid causing abdominal cramps (pain).

Q14. Which part of CNS controls respiration?
Medulla Oblongata is the lower half of the brain stem and it controls the respiration by activating the muscles for breathing mechanism.
Q15. What is micturition?

Q17. Progesterone is secreted by
Progesterone is hormone which regulates conception and pregnancy. Produced by ovary, placenta and adrenal glands.
Q18. Lysosomes are also known as -
Lysosomes are cellular organelle that contain hydrolase enzyme that breaks down waste material and cellular debris.
Q19. Sarcolemma is a covering of 
Sarcolemma is also called as myolemma , is a outer membrane of stratified muscle fibre.
Q20. Lungs are covered by 
Pleura is an exceedingly delicate serous membrane and is arranged in the form of a closed invaginated sac.
Q21. How many pairs of spinal nerves are in humans?
Spinal nerve is referred to as mixed nerve which carries motor, sensory and autonomic signals between spinal cord and body. total 31 pairs of spinal nerves are in humans.
Q22. The structural and functional unit of brain is?
Neuron is an electrically excitable cell that process and transmit information through electrical and chemical signal.
Q23. What is embolism?
Embolism is a fat globules or a gas bubble in a the bloodstream.
Q24. which one is a iron transporter in the blood?
Iron is released into the plasma to be recirculated by carrier protein called transferrin.
Q25. The deposition of sodium urate crystals in joints leads to disease -
Gout is the disorder of purine metabolism and occurs when its final metabolite uric acid crystallises to form monosodium urate crystals in joints, tendons and surrounding tissues and trigger a local immune inflammatory reaction.
