Close the boiling tube W by using cork
Drop the paraffin oil on the solution in boiling tube V
Increase the length of delivery tube from boiling tube V to W
Use unboiled sucrose solution
The following is the word equation for the energy production through process X.
What is X?
Glycolisis

Which of the following is the main role of Lactobacillus sp. in the making of Yogurt?
Lactobacillus sp. helps to coagulated casein
Lactobacillus sp. causes the yogurt become sour
Lactobacillus sp. undergoes fermentation and turn lactose to lactic acid
The following information is about two conditions of planting plants R and S.

While doing vigorous exercise, high accumulation of lactic acid occurs and the individual will inhale more oxygen to oxidize the lactic acid.
What are the causes this situation occurred?
I Oxygen debt occurred
II Aaerobic respiration occurred
III Less energy produced
IV More cxygen used for contraction and relaxation of muscle
I and II
II and III
III and IV
I and IV

during vigorous training
Which of the following processes involves aerobic respiration?
Yeast fermentation
Initial stage of seed germination
Heart muscle contract when a person is at rest
paddy plants under waterlogged condition
Which of the following causes oxygen debt to occur?
Oxygen demand exceeding oxygen supply
Increase in heartbeat
Rapid breathing
High level of carbon dioxide in the blood
Which of the following is the effect of high accumulation of lactic acid in the muscle during fermentation?
muscle cramp
muscle swollen
muscles degenerates
Muscle contracts rapidly
Which of the following is the differences between aerobic respiration and fermentation?
Aerobic respiration: Occurs in absence of oxygen
Fermentation: Occurs in the presence of oxygen
Aerobic respiration: Glucose is oxidised partially
Fermentation: Glucose is oxidised completely
Aerobic respiration: Produce carbon dioxide and water
Fermentation: Produce lactic acid and water
Aerobic respiration: Occur in cytoplasm and mitochondria
Fermentation: Occur in cytoplasm
