UPDATE 2024/2025
What is the purpose of cellular respiration?
ATP production
During metabolism organic compounds are__________to harvest energy from the chemical bonds.
oxidized
Oxidation involves__________ an ___________from an atom.
removing; electron
What is used to transfer electrons down to an electron acceptor?
electron carriers
What is the result of passing electrons down from one carrier to another?
Energy is released that can be used to produce ATP.
Why must the electrons be passed down through carriers as opposed to being passed directly to the
acceptor?
The cell might combust is you passed them directly to the electron acceptor because too much energy
might be released.
, What is the purpose of oxygen in respiration?
Oxygen acts as an electron acceptor during aerobic respiration.
Explain the process of aerobic respiration.
Glucose is oxidized into CO2 through the passing of its electrons to an O2 acceptor via electron carriers.
What step is glycolysis in respiration?
Glycolysis is the first step in respiration.
Where does glycolysis take place?
In the cytoplasm.
Glycolysis is the process of what?
Splitting glucose
How many reactions take place in glycolysis?
Ten
What are the first three reactions in glycolysis considered?
Priming reactions
What do priming reactions do?
They prepare glucoses to be split.
How many reaction are considered priming reactions?
Steps 1-3
What is Phosphorylation?
