Q

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

A

Q

why do we experience choking

A

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

Q

changes taken during exhalation

A

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

18
Q

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

A

diffusion

19
Q

in which blood does it have a dark red

A

de-oxygenated or carbondioxide rich blood

20
Q

how much percentage inhalted O2

A

21%

21
Q

how much percentage exhalted O2

A

16%

22
Q

how much percentage inhaled and exhaled nitrogen

A

78% and 78%

23
Q

why do mountaniers carry heavy oxygen cylinders

A

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

24
Q

what is the liquid part of blood

A

plasma

25
Q

what is cellular respiration

A

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

26
Q

what are eukariyotics

A

persence of nucleus

27
Q

what are prokariyotics

A

absence of nucleus

28
Q

difference between arobic and anerobic respiration

A

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

29
Q

flow chart of breakdown of glucose

A

ATP, phyruvic acid, presence and absence of O2

30
Q

MR for yest experiment- anerobic respiration

A

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

31
Q

what is fermentation

A

the process of convertion of sugars in alcohol

32
Q

what is fractional distilation

A

method by which mixture will be seperated based on boiling points

33
Q

places where fermentation is used

A

dosa, bear, wisky, bread

34
Q

difference between respiration and combustion

A

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

35
Q

activity of plants/ CO2 is evolved during respiration

A
36
Q

lab activity of combustion of sugar

A

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

37
Q

difference between photosynthesis and respiration

A

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

38
Q

activity of plants- heat is liberated during respiration

A
39
Q

alveoli spread out cover the area of

A

160 m2

40
Q

what is anabolic process

A

using smaller units/ materials and energy to produce molecules

41
Q

what is catabolic process

A

breaking down complex molecules to produce smaller units and energy
