Q

what is the fuel source for ATP-PC

A

creatine phosphate

17
Q

what enzyme breaks down PC

A

creatine kinase

18
Q

glucose is broken down into what during aerobic glycolysis

A

pyruvic acid

19
Q

what happens in the Krebs cycle

A

enzyme A is broken down to generate two ATP molecules and also the production of hydrogen and co2

20
Q

what happens in the glycolysis stage

A

if oxygen is present pyrucvic acid is converted to acetyl enzyme a and enter kerbs cycle
