36. What is the ultimate product of Glycolysis?
[A] Pyruvic acid
[B] Carbon dioxide
[C] Glucose
[D] Ethyl alcohol
Show Answer
Correct Answer: A [Pyruvic acid]
Notes:
Glycolysis, part of cellular respiration, is a series of reactions that constitute the first phase of most carbohydrate catabolism, catabolism meaning the breaking down of larger molecules into smaller ones. Glycolysis breaks down glucose and forms pyruvate with the production of two molecules of ATP. The entire process from conversion of glucose to pyruvate is anaerobic that is it does not take place in presence of oxygen.

38. Activity of an enzyme can be modulated by change of
____:
[A] pH
[B] Light
[C] Humidity
[D] Rainfall
Show Answer
Correct Answer: A [pH]
Notes:
Changes in pH which can accompany metabolic process such as respiration (aerobic glycolysis for example) can alter the conformation of an enzyme and hence enzyme activity such as salivarya mylase is effective in neutral condition, pepsin in acidic condition l.5 (less than pH 7) and trypsin in basic condition (more than pH 7).
39. Which among the following disease is NOT caused by viruses?
[A] Polio
[B] Chicken Pox
[C] Typhoid
[D] Influenza
Show Answer
Correct Answer: C [Typhoid]

[A] 15 times/minute
[B] 18 times/minute
[C] 26 times/minute
[D] 32 times/minute
Show Answer
Correct Answer: A [15 times/minute]
Notes:
New born babies and children normally breathe faster than older children and adults. Their respiratory rate is about 30-60 breaths per minute. The respiratory rate for the different age-categories of children is:-6-12 months: 24-30; 1-5 years: 20-30; 6-12 years: 12-20.
