20 ATP
What happens to excess ATP in the cell?
It is hydrolyzed back into ADP and Pi
It is stored for later use
It is converted into glucose
It is excreted as waste
What is the correct order of events in glucose oxidation
Glycolysis
Krebbs cycle
Oxidative phosphorylation
(electron transport chain)
(chemiosmotic coupling)
What is the term for the amount of energy required to raise the temperature of 1 gram of water by 1 degree Celsius?
Which process involves the breakdown of glucose to produce ATP in the absence of oxygen?
Anaerobic glycolysis
Aerobic respiration
Krebs cycle
Electron transport chain
What is the term for the amount of energy expended at rest to maintain basic physiological functions?
