respiration

Question 1

CO2 is also known as

Answer 1

fixed gas or chalky acid gas

Question 2

what is vitiated air?

Answer 2

where both CO2 and O2 is presence but theres removal of respirable air 02

Question 3

O2 is also known as

Answer 3

respirable air

Question 4

steps of respiration

Answer 4

1) breathing
2) gasious exchange at lungs level
3)gas transport by blood
4)gasious exchange at tissue level
5)cellular respiration

Question 5

what is breathing

Answer 5

taking in of O2 from environment and giving out CO2 is called breathing

Question 6

define inhalation and exhalation

Answer 6

inhalation- the process of taking in air containing more O2
exhalation- the process of taking out the air containng more CO2

Question 7

how much percent of CO2 do we release

Answer 7

44%

Question 8

how much CO2 is present while we inhale

Answer 8

0.03%

Question 9

draw pathway of air with diagram

Answer 9

nostrils, nasal cavity, pharynx, larynx, trachea, bronchus, bronchilous, alveolus

Question 10

what is the function of epiglottis by the passage of air and food

Answer 10

epiglottis closes the way of lungs when we eat and closes the way of food pipe when we breath

Question 11

why do we experience choking

Answer 11

when we eat and talk at the same time- sometimes making the epiglottis to open the way to lungs and the food goes inside- we face difficulty in breathing tears cough

Question 12

name the fluid membrance in lungs

Answer 12

pleura

Question 13

name the structures helping the lungs to expand and relax

Answer 13

chest wall muscle, diaphran

Question 14

draw the structure of lungs and label its diagrm

Question 15

state the importance of diaphram

Answer 15

1)it divides two cavities chest and abdominal cavity

Question 16

what are the changes taken during inhalation

Answer 16

1)diaphram contacts and becomes flat
2)volume of chest cavity increase
3)internal air decreases
4)chest wall moves up

Question 17

changes taken during exhalation

Answer 17

1)diaphram relaxes and forms a dome structure
2) volume of chest cavity decerases
3)internal air pressure will increase
4)chestwall moves down

Question 18

by which process does gacious exchange at lungs and blood takes place

Answer 18

diffusion

Question 19

in which blood does it have a dark red

Answer 19

de-oxygenated or carbondioxide rich blood

Question 20

how much percentage inhalted O2

Answer 20

21%

Question 21

how much percentage exhalted O2

Answer 21

16%

Question 22

how much percentage inhaled and exhaled nitrogen

Answer 22

78% and 78%

Question 23

why do mountaniers carry heavy oxygen cylinders

Answer 23

they are above the sea level- means less oxygen
hemoglibin usually takes 4 molecules but in hights it only take 2 molecules of oxygen- difficulty in breathing

Question 24

what is the liquid part of blood

Answer 24

plasma

Question 25

what is cellular respiration

Answer 25

the pathway by which cell releases energy by breaking chemical bonds of glucose is called cellular respiration- very important process

Question 26

what are eukariyotics

Answer 26

persence of nucleus

Question 27

what are prokariyotics

Answer 27

absence of nucleus

Question 28

difference between arobic and anerobic respiration

Answer 28

1)presence and absence of oxygen 2)takes place in cytoplasm and mitocondria/ only cytoplasm 3)more/less amount of energy 4)C6H1206 is completely breaked down/ complete and incomplete oxidation 5)energy stored in ATP 36-38 molecules/ 2moluclels 6)end products CO2 and H2O / lactic acid ethanol CO2 7)ex-animals humans / bacteria yeast

Question 29

flow chart of breakdown of glucose

Answer 29

ATP, phyruvic acid, presence and absence of O2

Question 30

MR for yest experiment- anerobic respiration

Answer 30

janus green blue, paraffin liquid, clucose solution, thermoflask, yeast, wash bottle, lime water, thermometer, 2 holes splitted cork, delivary tube

Question 31

what is fermentation

Answer 31

the process of convertion of sugars in alcohol

Question 32

what is fractional distilation

Answer 32

method by which mixture will be seperated based on boiling points

Question 33

places where fermentation is used

Answer 33

dosa, bear, wisky, bread

Question 34

difference between respiration and combustion

Answer 34

occurs in living/ non-living cell controllable/ un-controllable less than 50% / all energy is liberated as heat energy is released in stepwise/ all together

Question 35

activity of plants/ CO2 is evolved during respiration

Question 36

lab activity of combustion of sugar

Answer 36

sugar, testtube, 1hole split cork, bunsen burner,limewater,delivarytube

Question 37

difference between photosynthesis and respiration

Answer 37

greenplants/humanbeings, sunlight,day and night, can survive/cannot survive, few cells/ all cells, CO2 O2/ O2 and CO2

Question 38

activity of plants- heat is liberated during respiration
