Introduction and types of respiration - Advance

Dear Readers,

Three types of respiration include internal, external, and cellular respiration. External respiration is the breathing process. It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells.

Q1.  During anaerobic respiration, one molecule of pyruvic acid

•  Losses 3 molecules of ATP
•  Losses 6 molecules of ATP
•  Gains 2 molecules of ATP
•  Gains 4 molecules of ATP

Losses 3 molecules of ATP

Q2.  Anaerobic respiration is also known as

•  Intramolecular respiration
•  Intermoleculer respiration
•  Extramolecular respiration
•  Molecular respiration

Intramolecular respiratione

Q3.  Vant Hoff's law states that

•   The respiration rate increases two or three times for every rise of 5^o C
•  The respiration rate decreases two or three times for every rise of 10^o C
•   The respiration rate does not increase or decrease with change in temperature
•   The respiration rate increases two or three times for every rise of 10^o C

The respiration rate increases two or three times for every rise of 10^o C

Q4.  Slow respiring plants or plant tissues are

•  Promeristems
•  Cambium
•  Leaf primordia and young plant
•  Adult plants and matured tissues

Adult plants and matured tissues

Q5.  The tissue of highest respiratory activity is

•  Meristems
•  Ground tissue
•  Phloem
•  Mechanical tissue

Meristems

Q6. Why do fruit juices turn bitter if kept in an open place for sometime

•  Juices have something inside them which makes it bitter
•  It is due to fermentation brought about by yeast cells
•   It is due to the activity of fungi present in the atmosphere
•   All the above

It is due to fermentation brought about by yeast cells

Q7.  The RQ (Respiratory quotient) of C₃₉H₇₂O₆ is

•  2.71
•   1.34
•  0.72
•   3.250

0.72

Q8.  The net gain of energy from one molecule of sucrose in aerobic respiration is

•   8 ATP
•  38 ATP
•  40 ATP

80 ATP

Q9.  What is the last substrate to be used in respiration

•  Glucose
•  Fats
•  Organic acid
•  Proteins

Organic acid

•  686000 cal
•   304000 cal
•  277400 cal
•   686 cal

277400 cal
