Respiration

Question 1

We take in oxygen to do what n liberate what ?

Answer 1

O2> breakdown of glucose to form ATP > liberate CO 2 , energy n water

Question 2

At cellular level break down of glucose takes place in

Answer 2

Cytoplasm

Question 3

6 carbon glucose breaks down into

Answer 3

3 carbon knwn as Pyruvate

Question 4

ATP is imp y ?

Answer 4

To continue life processes

Question 5

In presence of oxygen pyruvate breaks down into

Answer 5

CO2 +energy+Water

Question 6

Where does the breakdown takes place when there is presence of oxygen

Answer 6

Mitochondria

Question 7

Where does the breakdown takes place in absence of oxygen

Answer 7

Yeast

Question 8

In absence of O2 what products are made

Answer 8

Ethanol ( 2 Carbon) + energy +CO2

Question 9

In lack of oxygen pyruvate breaks down into

Answer 9

Lactic acid+ energy

Question 10

Where does breakdown takes place when there is lack of oxygen

Answer 10

Muscle cells

Question 11

Aerobic n an aerobic respiration

Question 12

Rate of breathing in aquatic animals is more than territorial animals . Why

Answer 12

The rate of diffusion of oxygen is less in water as compared to air

Question 13

What factors in which direction of diffusion is dependent on

Answer 13

• plant requirement
• Environmental conditions

Question 14

At night what is released by plants

Answer 14

CO2 as there is no photosynthesis taking place . Whereas in day this CO2 is taken up by plant to produce O2 so O 2 is released in daytime

Question 15

The energy released during aerobic respiration is greater than anaerobic respiration. T or F

Answer 15

True

Question 16

ATP in energy drives ____ reactions

Answer 16

Endothermic

Question 17

The energy released in respiration is used to form ATP from ?

Answer 17

ADP n inorganic Phosphate

Question 18

Plants respiration takes place via ( 3 things )

Answer 18

Stomata
Diffusion
N Large intercellular spaces help that all cells are in contact with the air

Question 19

In humans respiration takes place via

Answer 19

Lungs ( air passages )
Haemoglobin

Question 20

Haemoglobin has highest affinity towards

Answer 20

CO ( carbon monoxide)

Question 21

Respiratory pigment

Answer 21

Haemoglobin

Question 22

Air pathway in lungs

Answer 22

Nostrils>buccal cavity> pharynx>Larynx>Trachea>Bronchi>Bronchioles >Alveoli ( where through diffusion at cellular level exchange of gases takes place

Question 23

Voice box

Answer 23

Larynx

Question 24

Ring of cartilage and helps in preventing collapse of air passage

Answer 24

Trachea

Question 25

When we breathe in

Answer 25

Lift our ribs Chest cavity expanda Diaphragm FLATTEN

Question 26

Y lungs have residual air

Answer 26

So that we get time to Absorb Oxygen and release CO2

Question 27

Red colour of haemoglobin is due to

Answer 27

Presence of CO

Question 28

Which is more soluble in water CO2or O2

Answer 28

CO2- that's y carried is dissolved form

Question 29

Alveoli surface area

Answer 29

80 m square

Question 30

Y we require haemoglobin

Question 31

Y can we respire just by respiration

Answer 31

Bcoz of large surface area the process will be slow

Question 32

Y smoking causes lung cancer

Question 33

Haemoglobin has high affinity towards

Answer 33

Oxygen ( n highest with CO )

Question 34

Respiratory pigment carries

Answer 34

CO2 O2 Waste
