Phosphocreatine made up of creatine with high energy phosphate bond. Creatine is a supplement that anaerobic athletes use to increase PC stores. PC is used to re-synthesis ATP enzyme-creatine kinase

anaerobic- type of reaction
sarcoplasm- site of reaction
phosphocreatine- fuel
creatine kinase- controlling enzyme
no by products
2-10 seconds
pro - no delay for oxygen
PC readily available in the muscle cell
cons- low ATP yield and small PC stores lead to rapid fatigue.

glycogen -> glucose ( glycogen is broken-down by the enzyme GPP- glycogen phosphoryase).
 glucose -> pyruvic acid (glucose is made in to pyruvic acid using PFK- phosphofructokinase, an enzyme which catalyzes the breakdown of  glucose).
glycolysis  is the partial breakdown of glucose into pyruvic acid, this process leads to energy being released, 2 phosphates and 2 adp which bind to the phosphate ions to become re-synthesized ATP.
pyruvic acid-> lactic acid( from the enzyme LDH, lactate de hydrogenase). the lactic acid causes pain, fatigue through the inhibiting of enzymes; for example PFK ATPase.
SUMMARY:
type of reaction- anaerobic.
site of reaction- sarcoplasm
fuel- glycogen/glucose
controlling enzyme- GPP,PFK and LDH
ATP yield- 1:2
by products- lactic acid.
intensity & duration- maximal intensity and short duration (up to 3 minutes depending on the intensity).
STRENGTHS:
no delay for O2
relatively fast fuel breakdown for atp
provides energy for high intensity exercise.
WEAKNESSES:
fatiguing by products: lactic acid 
relatively low atp yield

Glycogen catalysed by GPP, creates glucose. Fat/triglycerides (by lipase) and proteins can be broken down into glucose. Glucose is then broken down by PFK into pyruvic acid/pyruvate. This process (glycolysis) creates energy + 2ADP + 2P to resynthesize 2ATP in sarcoplasm. As it has sufficient oxygen, no lactic acid is produced so pyruvic acid, in a linked reaction, is catalyzed by co-enzyme A to create Acetyl CoA which allows access to mitochondria. ``

Kreb's cycle:
Takes place in mitochondria and produces high levels of energy. This enables performance at a low-moderate intensity for a long period of time. Acetyl CoA combines oxaloacetic acid to form citric acid. Citric acid is then oxidised thorugh the cycle of reactions known as the webs cycle. What happens as a result? CO2 and H2O produced. Another 2ATP produced. This occurs in the matrix of the mitochondria. Hydrogen ions are formed and removed into next stage.

Electron transport chain:
The ETC takes place again in mitochondria, but this time in the Christae. HYDROGEN IONS ARE CARRIED BY CO ENZYMES NAD AND FAD (HYDROGEN CARRIERS) . tHIS THEN SPLITS H INTO HYDROGEN IONS AND HYDROGEN ELECTRONS. hYDROGEN IONS OXIDISED AND REMOVED AS H2O. PAIRS OF HYDROGEN ELECTRONS ARE CARRIED BY NAH (NADH2) WHICH RELEASES ENOUGH ENERGY TO RESYNTHESISE 30ATP.

All together this produces enough energy to resynthesise 38ATP which gives a yield ratio 1 mole of glucose:38 moles of ATP.

You can use your books, the internet and each other for this task. ]]> 2021-04-25 19:51:08 UTC https://padlet.com/maxwenley97/jy39mtrppr7a4nox/wish/1456903538
