Formation Of ATP Flashcards
Name the three ways ATP can be formed:
Phosphocreatine reaction
Glycolysis
Oxidation
Respiration is an exergonic or endergonic reaction?
Exergonic
Is the Phosphocreatine reaction aerobic or anaerobic?
Anaerobic
The Phosphocreatine reaction takes place in the ?
Cytoplasm
One mole of ATP is equal to how many calories?
7
We only store around ?? Of energy in the form of ATP at any one time
5-6
In the Phosphocreatine reaction, which molecule is used to store ATP?
Phosphocreatine
What is Phosphocreatine used to recombine?
ADP + Pi into ATP
Glycolysis is the breakdown of glucose into what?
Two molecules of pyruvate acid (aerobically) Lactic acid (anaerobically)
What is the net gain of glycolysis?
Two ATP
Name the two Lachesis of glycolysis?
Energy investment phase
Energy generation phase
The krebs cycle is also known as the ?
Citric acid cycle
Where does the Krebs cycle take place
In the matrix of the mitochondria
What happens during the process of reduction?
Electrons are gained
Foods contain energy in the …..?
Chemical bonds between molecules in the macronutrients
Name the three macronutrients
Carbohydrates
Protein
Fats
What type of energy is an ATP molecule?
Chemical energy
The usable energy in ATP is stored in….?
Bonds between the phosphate groups
ADP
Adenosine diphosphate
ATP
Adenosine triphosphate
ATP consists of which groups?
Adenosine and
Ribose groups
Attached to the triphosphate group
The liberation of energy from ATP is a ? reaction?
Catabolic (breakdown)
The splitting process of ATP into ADP + Pi + free energy is called?
Hydrolysis
The breakdown of ATP is catalysed by which enzyme?
ATPase
Pi is an?
Inorganic phosphate
What is the simplest method of re-synthesising ATP?
The Phosphagen System
Describe the Phosphagen System…..
Energy is stored in the molecule Phosphocreatine (PCr). The energy in PCr is released and used to recombine ADP and Pi as ATP
Which enzyme catalyses the reaction to release energy from the PCr molecule?
Creatine kinase
Which enzyme catalyses the reaction to store some energy with the ATP molecule?
ATPase
Energy transfer in phosphate bonds is called?
Phosphorylation
The Phosphagen System is the main energy system used to resynthesise ATP for about ?-? seconds of exercise
6-9 seconds
The PCr hydrolysis and adenylate kinase reactions generate?
Pi - inorganic phosphate
ADP - adenosine diphosphate
AMP - adenosine monophosphate
The byproducts of the Phosphagen System stimulate?
Glycogenolysis
Glycolysis
Respiratory pathways of mitochondria
Describe the adenylate kinase reaction, part of the Phosphagen System?
Two ADPs are used to resynthesise one ATP molecule with the production of an AMP molecule
