historical history day

well, last friday was my last day touching history in my whole life...i hope...and it was practically a HISTORICAL HISTORY day...u know if u know and son need to know if u dont...

through what happened i realised lotsa things...life is really not only bout exams and test...if you realised you had disappoint someone who care and concern bout you so much, how would u feel???

i really dunno what else can i ask for when i know i have lotsa ppl around me who care and love me... im gonna try my best and strive for the best to make everyone proud of me.i know i can do it!!

heart filled with appreciation....

revenge

so yeah, my body is taking its revenge..and i partially lose to it...hope i'll get well soon and continue to fight for the coming war...

final lap of mine...

the last 2 weeks that i can changed nothing to something....gonna give all out and pray that god bless me...i hope what i did is enough to reach my target...and i know I CAN DO IT!! :)

hope that you will be with me till the very end through this long and tough journey...

anaerobic respiration in human muscle cells

1.during vigorous activities, the breathing rate and heart beat rate increases to supply sufficient oxygen for rapid muscles contraction

2. however, the supply of oxygen is still not enough and muscle cells have to carry out anaerobic respiration

3. the main substrate is anaerobic respiration.

4. glucose is broken down to form lactic acid and energy for muscles contraction. only a small amount of energy is produced cause the glucose broken down partially.

5. the energy released is used to produce ATP. some lost as heat.

6. accumulation of lactic acid causes muscles fatigue.

7. lactic acid is transported back to the liver. 20% lactic acid is used for aerobic respiration to produce energy, CO2 and water.

8. oxygen is required for aerobic respiration. rapid breathing and heart beat rate continues. oxygen break down lactic acid built in muscles.

9. energy produced frm aerobic respiration used by liver cells to convert back lactic acid to glucose

10. oxygen debt occurs because the oxygen demand is more than the supply of oxygen. when all the lactic acid is oxidised, oxygen debt is paid

11. chemical equation : C6H12O6 = 2C3H6O3 + energy

anaerobic respiration in yeast

anaerobic respiration respiration is the oxidising of glucose in cell to produce energy ATP without the presence of oxygen.

1. anaerobic respiration occurs in the cytoplasm in yeast during the absence of oxygen.
2. the main substrate is glucose
3. oxidation of glucose produce ethanol, CO2 and a little energy.
4. reaction is catalysed by ZYMASE . only a little energy is produced because break down of glucose is not complete.
5. energy produced generate ATP
6. anaerobic respiration of yeast is called FERMENTATION
7. chemical equation : C6H12O6 = 2C2H5OH +2 CO2 energy
8. products of frementation is used as raising agent in baking or wine.

aerobic respiration

aerobic respiration: oxidation of glucose in the cell to produce energy with the presence of oxygen

1. aerobic respiration occurs in e cytoplasm and proceed to the mitochondria...
2. aerobic respiration occurs when there is adequate oxygen supply
3. the main substrate of e aerobic respiration is GLUCOSE
4. glucose is oxidised to produce co2, water and energy. oxygen is used in oxidation.
5. each stage is catalyst by an enzyme
6. most energy is converted to ATP from ADP. some energy is lost by heat
7. chemical equation : C6H12O6 + 6O2 = 6CO2 + 6H2O + energy

time flies...

seriously...after 11 years of school days, my life is left with 10 official school days...should it be a happy or sad news?hmmm...i think i wil really miss school life but everything will remain as memories...

1o days to finish school, 18days to spm, and another 11exam days and my schooling life will really end with a FULLSTOP!

GOD save my soul...guide me pls to overcome these coming about 2 months...my future will be all depend on it....pray hard and i gonna do all i can...i'll do my best and i believe GOD will do the rest for me...

i'll keep trying till the last day and i'll never say i give up!!

never say never will be my SPIRIT!!!
