RESPIRATION (RESPIRASI)
Subtopic (Subtopik) :
1. The respiratory process in energy production (Proses respirasi dalam penghasilan tenaga)
2. The respiratory structure and breathing mechanisms in humans and animals (Struktur respirasi dan mekanisme pernafasan dalam manusia dan haiwan)
Do you know that your body is like a rechargeable battery?
This is because when your body weak (uncharged battery), you need to eat (recharge battery) to
get energy.
In this section, (Dalam bahagian ini) :
1. What is respiration? (Apakah respirasi ?)
2. What is the main substrate that involved in energy production? (Apakah substrat utama yang terlibat dalam penghasilan tenaga)
3. What is ATP? Why is it important? (Apakah ATP? Mengapa ATP penting?)
4. What are Aerobic and Anaerobic Respiration? (Apakah respirasi aerob dan anaerob?)

RESPIRATION (Respirasi)
is (ialah)
Proses obtaining (Proses pemerolehan) O2
and (dan)
O2
Delivers to(diangkut ke)
CO2
and (dan)
Remove from(disingkirkan dari)
RESPIRATION (Respirasi) occur in 2 stage (berlaku dalam 2 peringkat)
EXTERNAL RESPIRATION(Respirasi luar)
between (antara)
INTERNAL RESPIRATION/ CELLULAR RESPIRATION(Respirasi luar)
Process exchange of gases (Proses pertukaran gas)
respiratory surface of organism (Permukaan respirasi
organisma)
with (dengan)
Its environment continuously (persekitarannya secara
berterusan)
Process oxidation & breakdown of glucose (Proses pengoksidaan dan
penguraian glukosa)
for (untuk)
produce energy (menghasilkan tenaga)

Lead to
Internal respiration / Cellular respiration
( Respirasi dalam /
Respirasi sel)
O2 + GLUCOSE (get from food)
To produce energy used for cell activities
Is energy required for the following processes?
Muscle contraction for movement?
Active transport of substances?
Digestion of food?
Impulses transmission for response?
Cell division for growth?
Keep body at constant temperature?
Excretion of waste products?
Meiosis for reproduction?
Mitosis for cell division?
Synthesis of proteins, hormones, lipids & enzymes?
Inhalation & exhalation for breathing?
All organisms require ENERGY to carry out all living processes!!!
Cellular respiration (Respirasi sel)
Aerobic respiration(Respirasi aerob)
Glucose Carbon dioxide ENERGY
sfat Oxidation of glucose(Pengoksidaan
glukosa)
Adenosine triphosphate(Adenosina trifosfat)
Phosphate bond which can easily broken(Ikatan fosfat yang boleh diputuskan dengan
mudah)
P
ATP in Action
A P P P ProcessI NEED ENERGY PLEASE!
Woohoo! I’m Energized!
ATP, the energy “currency” of the cell
ADP
ANAEROBIC RESPIRATION(Respirasi anaerob)
LETS WE TAKE A LOOK WHAT HAPPEN WITH MUSCLE CELL AFTER PROLONGED PHYSICAL ACTIVITY (Mari kita lihat apa yang berlaku kepada sel otot selepas aktiviti kecergasan)
Anaerobic respiration(Respirasi anaerob)
What is anaerobic respiration? (Apakah respirasi anaerob)
Process of oxidation of glucose to produce energy in the absance of
oxygen.(Proses pengoksidaan glukosa untuk
menghasilkan tenaga dalam ketiadaan oksigen)
Rate of respiration increase
(Kadar pernafasan meningkat)
Rate of heartbeat increase
(Kadar denyutan jantung meningkat)
The respiratory structure and breathing mechanisms in humans and animals
(Struktur respirasi dan mekanisme pernafasan dalam manusia dan haiwan)
2. The respiratory structure and breathing mechanisms in humans and animals (Struktur respirasi dan mekanisme pernafasan dalam manusia dan haiwan)
In this section, (Dalam bahagian ini) :
1. What is respiratory structure? (Apakah struktur respirasi ?)
2. What is the relationship between surface area per volume ratio of organism with their gas exchange? (Apakah perkaitan antara luas permukaan per isipadu dengan proses pertukaran gas)
3. What are respiratory structure and breathing mechanism of insects, amphibian, fish and human? (Apakah struktur respirasi dan mekanisma pernafasan dalam serangga, amfibia, ikan dan manusia)
What is gaseous exchange process? Where exchanges of respiratory gases occur? (Apakah proses pertukaran gas? Di manakah
pertukaran gas respirasi berlaku)
In respiratory surface (Dalam struktur respirasi)
Diffusion (Resapan)
Thin surface layer of
respiratory structure
Large surface area for
respiratory structure
Entire plasma membrane (Seluruh membran plasma)
Large surface area compared to
volume of their body
Moist plasma membrane
( Membran plasma yang lembap)
Surface area available for gaseous exchange per unit volume of organisms.
Before we learnt about surface area per volume ratio, lets we know what is
surface area per volume ratio.
Relationship between surface area per volume (SA /V) ratio of organisms with their gas exchange process (Perkaitan antara luas permukaan per isipadu dengan proses pertukaran gas)
large
besar
Small organisms have large surface area
available for gaseous exchange per unit
volume of organisms.
Large organisms have small surface area available for gaseous exchange per unit volume of
organisms.
