Respiration Flashcards
We take in oxygen to do what n liberate what ?
O2> breakdown of glucose to form ATP > liberate CO 2 , energy n water
At cellular level break down of glucose takes place in
Cytoplasm
6 carbon glucose breaks down into
3 carbon knwn as Pyruvate
ATP is imp y ?
To continue life processes
In presence of oxygen pyruvate breaks down into
CO2 +energy+Water
Where does the breakdown takes place when there is presence of oxygen
Mitochondria
Where does the breakdown takes place in absence of oxygen
Yeast
In absence of O2 what products are made
Ethanol ( 2 Carbon) + energy +CO2
In lack of oxygen pyruvate breaks down into
Lactic acid+ energy
Where does breakdown takes place when there is lack of oxygen
Muscle cells
Aerobic n an aerobic respiration
Rate of breathing in aquatic animals is more than territorial animals . Why
The rate of diffusion of oxygen is less in water as compared to air
What factors in which direction of diffusion is dependent on
- plant requirement
- Environmental conditions
At night what is released by plants
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
The energy released during aerobic respiration is greater than anaerobic respiration. T or F
True
ATP in energy drives ____ reactions
Endothermic
The energy released in respiration is used to form ATP from ?
ADP n inorganic Phosphate
Plants respiration takes place via ( 3 things )
Stomata
Diffusion
N Large intercellular spaces help that all cells are in contact with the air
In humans respiration takes place via
Lungs ( air passages )
Haemoglobin
Haemoglobin has highest affinity towards
CO ( carbon monoxide)
Respiratory pigment
Haemoglobin
Air pathway in lungs
Nostrils>buccal cavity> pharynx>Larynx>Trachea>Bronchi>Bronchioles >Alveoli ( where through diffusion at cellular level exchange of gases takes place
Voice box
Larynx
Ring of cartilage and helps in preventing collapse of air passage
Trachea
When we breathe in
Lift our ribs
Chest cavity expanda
Diaphragm FLATTEN
Y lungs have residual air
So that we get time to Absorb Oxygen and release CO2
Red colour of haemoglobin is due to
Presence of CO
Which is more soluble in water CO2or O2
CO2- that’s y carried is dissolved form
Alveoli surface area
80 m square
Y we require haemoglobin
Y can we respire just by respiration
Bcoz of large surface area the process will be slow
Y smoking causes lung cancer
Haemoglobin has high affinity towards
Oxygen ( n highest with CO )
Respiratory pigment carries
CO2
O2
Waste
