Cellular Respiration (7) Flashcards
What is cellular respiration?
It is a series of metabolic pathways (under the control of enzymes) that bring about the release of energy from glucose and the regeneration of the high energy molecule ATP.
What causes the release of energy in a cell during respiration?
Oxidation of glucose using dehydrogenase enzymes
What does the release of energy through oxidation lead to?
The removal of hydrogen ions and the production of ATP
What does ATP stand for?
Adenosine Triphosphate
What is transferred from ATP in order for it to be used as a source of energy?
Chemical energy
What functions in a cell require energy (ATP)?
Muscle Contraction
Protein Synthesis
Active Transport
Nerve Transmission
Cell Division
DNA Replication
Where do the 3 stages of respiration take place?
Mitochondria
What are the 3 stages of respiration?
Glycolysis
Citric Acid Cycle
Electron Transport Chain
Where does glycolysis take place?
Cytoplasm
In what conditions does glycolysis take place?
During the presence or absence of oxygen (fermentation)
Where does the Citric Acid Cycle take place?
The central matrix of mitochondria
Where does the Electron Transport Chain occur in mitochondria?
It takes place in the mitochondrial membrane
