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?)

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)

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)

Small organisms have large surface area available for gaseous exchange per unit volume of

organisms.

Large organisms have small
