Aerobic & Anaerobic Cellular Respiration Flashcards
What is Cellular Respiration?
A series of reactions that break down glucose needed to carry the functions of life.
What are the overall reactions for aerobic cellular respiration?
Oxygen
Glucose
What are the overall products of aerobic cellular respiration?
36-38 ATP
Where does cellular respiration occur within the cell?
Cytoplasm
Mitochondria
In what organelle does MOST of aerobic cellular respiration occur?
Mitochondria
What are the 4 stages of aerobic cellular respiration?
- Glycolisis
- Link reaction
- Kreb cycle
- Electron transport chain
What happens during glycolysis?
Glycolysis is the first stage of cellular respiration of both aerobic and anaerobic: fermentation
This process occurs in the abscence of oxygen
2 NADH and 2 ATP are formed
Which stage occurs in the abscence of oxygen?
Glycolysis
What happens during the Link Reaction stage?
In the presence of oxygen, glucose is converted into 2 pyruvate molecules and they enter the mitochondria converting into AcetylCoA
In what stage is AcetylCoA converted into citric acid and 2 ATPs are produce, as well as 2 NADH and 4 FADH
Kreb Cycle
What is the name of the final stage of aerobic cellular respiration, where NADH and FADH enter and 32-34 ATPs are formed?
Electron Transport Chain
What is fermentation?
A way of making ATP from glucose in the absence of oxygen.
What stage does aerobic cellular respiration and fermentation share?
Glycolysis
In what part of the cell does fermentation occur?
Cytoplasm
What is the starting reactant in fermentation and how many ATPs are produced?
Glucose
2ATPs
What are the two types of fermentation?
Lactate fermentation
Alcohol fermentation
Human muscle cells carry out what type of fermentation when they can´t get enough oxygen to meet their energy needs?
Lactate fermentation
What is the starting reactant of lactate fermentation?
Glucose
What are the final products of lactate fermentation?
2 ATPs
2 lactates
NADH is regenerated to ADP
Many bacteria and yeast carry out what type of fermentation, and they are used to make yogurt, bread, wine and biofuels.
Alcohol fermentation
In what type of fermentation is the starting reactant is glucose and the final products are 2 ethanols and 2 carbon dioxides.
Alcohol fermentation
