1. RESPIRATORY SYSTEM = System that supply O2 from the blood and removes

CO2 and other waste product

2) ANABOLISM = Synthetic metabolism where small molecule unite

to form larger molecule

3) CATABOLIS = Destructive metabolism that breaks own large

m0lecules which used energy

3) METABOLISM = Anabolism and catabolism that occur with chemical

change in living things

5) RESPIRATION = Chemical breakdown of food to release energy for

living things

6) AEROBIC = Process of food breakdown that involve oxygen

7) ANAEROBIC = Food oxidised without using oxygen

8) RESPIRATORY SURFACE = The site of gaseous exchange

INTERN L RESPIR TIONC6H12O6+ 6O2 6CO2 + 6H2O + ATP

AEROBIC

Glucose + O2

CO2 + Water + ATP(2880kJ)

ANAEROBIC

Muscle cells

Glucose Lactic acid

(2C3H6O3) + ATP (150kJ)

Plant cells

Glucose Ethanol(2C2H5OH) + CO2 + ATP(210kJ)

AEROBIC ANAEROBIC

SIMILARITIES

Both cellular respirationUse glucose for energy (ATP)Occur in plant an animalCatalysed by enzyme

DIFFERENCES

Use oxygen Without oxygen

Occur - cytoplasm- mitochondria

Occur - cytoplasm

Complete oxidation Incomplete oxidationRelease 38 ATP molecules Release 2 ATP molecules

Occur- all higher organism

Occurlower organism- Cell of higher organism

Breathing or process of exchanging oxygen and carbon dioxide between

organism and its environment

PHOTOSYNTHESIS RESPIRATION

SIMILARITIES

Occur intracellularlyDepends on the exchange of gas via stomata and lenticelsCatalysed by intracellular enzyme

DIFFERENCES

Carbohydrate as energy ATP as energyUse-CO2-water

Use-O2-Glucose

Involve anabolic process Involve catabolic process

Occur when cell contain-Chlorophyll- sunlight

Occur all the time

Gain dry mass Loss dry mass

Food consume Mitochondria


10/10

EXERCISE1. State two types of respiration
