Q

difference

differenciate between aerobic and anaerobic respiration

4 points

A

aerobic
1. in the presence of oxygen
2. glocuse + oxygen->carbondioxide+water +energy
3. 1 glocuse molecule produces 38 atpenergy
4. more efficiant
anerobic
1. in the absence of oxygen
2. glocuse–>lactic acid+energy
or
glocuse —>ethyle acid + co2+energy
3.1 glocuse molecule produces2 atp energy
4.less efficiant

Q

explanation

respiration of amobea

3 marks

A

Oxygen is entered by diffusion from sell wall into the body.
In return co2 formed when it combines with glocuse to release atp energy co2 and water vapour. Carbondioxide produced during respiration difuses out of the amobea cell into water.

you can try to compress in the exam if for lesser marks

18
Q

where is the respiratory system present? protected by the rib cage

A

it is present in the chest cavity protected by the rib cage

19
Q

what happens to different organs during inhalation

ex. diaphram –> dash

4 organs

A

lungs—->expands

ribcage—->moves upward
diaphram—>contracts
chest cavity—>volume increases

this can be written in a table

20
Q

what happens to different organs during exhalation?

ex. diaphram –> dash

4 organs

A

lungs—->contracts
ribcage—->moves downward
diaphram—>expands
chest cavity—>volume decreases

this can be written in a table

21
Q

What is the significance of floating ribs?

A

it makes it easy for the lungs to expand and contract during respiration.

22
Q

What are the similarities of inhalation and exhalation?

A

-both are physical changes
-both are a part of breathing
-both are interactions of the surroundings
