energy systems, ATPase, endothermic reaction - Coggle Diagram
energy systems
ATP (adenosine triphosphate)
adenosine
+
P-P-P (phosphate)
= adenosine triphosphate
ATP is the biological currency of the body
adenosine
+
P-P
release 3rd phosphogen = ADP
ADP releases energy to fuel metabolic reactions
ATP is the only usable source of energy
powers movement (contractions)
exists in all cells
all cellular metabolic reactions are powered by ATP
stored for 2-3 seconds
can be resynthesised
ATPase is activating enzyme
resynthesising formulas = ADP + P + energy = ADP
ATP store
phsophogen system
releases energy into ATP store to resynthesise ATP from ADP
very powerful but very short (10s) and small
lactate store
also can help resynthesises of ATP
quick release, not quite as fast as phosphogen release (lasts up to 120s)
glycogen store
releases energy to resynthesise large amounts of ATP
slow release
fat stores
released to resynthesise ATP
extremely slow
3 energy systems
ATP-PC System (Phosphagen System)
Glycolytic System (Anaerobic System)
Oxidative System (Aerobic System)
anaerobic exercise
ATP-PC system

ADP

P

energy = movment
when ATP system levels falls it activates creatine kinase (enzyme - helps resyntheise)
PC (in sarcoplasm of muscle)
PC (phosphocreatine) in the presence of creatinekinase produces =
creatine
+
Phosphate
+
energy = ADP
1 more item...
however cant use this energy to produce movement so parts of it are donated (ADP leftover, Phosphate, energy)
subsequent reaction =
ADP leftover + Phosphate + binding agent (energy) = ATP
then we have got the ATP back so can restart this process
