Cellular Respiration Flashcards
What carrier is produced in Glycolysis?

What is the final electron acceptor?
Oxygen
A child born without mitochondria relies on what to produce ATP?
Lactic Acid Fermentation
The Electron Transport Chain is located where?
The inner membrane of the mitochondria
Does Glycolysis require oxygen?
No
Where does Fermentation take place?
Cytoplasm
What are the steps of cellular respiration?
Glycolysis→Krebs Cycle→Electron Transport Chain
What steps does cellular respiration go through if oxygen is not present?
Glycolysis→Alcoholic Fermentation or Glycolysis→Lactic Acid Fermentation
Does the Kreb Cycle require light?
No
What type of molecule carries the most energy?
It ends with H
Why do cells use fermentation?
It allows ATP to be produced in the absence of oxygen
Aerobic
Needs air
Anaerobic
Does not need air
Chemical formula for cellular respiration
C6H12O6 + 6O2→6CO2 + 6H2O + ATP
What is used to kickstart Glycolysis?
2 ATP
Which metabolic pathway is common in anaerobic and aerobic metabolism?
Glycolysis
If you are asked to go up and down stairs what are they going to measure?
Lactic Acid build up
During what process is water produced?
Electron Transport Chain
What is the main difference between photosynthesis and cellular respiration?
Cellular respiration produces a usable energy molecule and photosynthesis produces a molecule of stored energy
What organelle does cellular respiration occur in?
Mitochondrion/Mitochondria
What is the total net ATP produced from aerobic respiration?
