The Types of Respiration
100
What are the three stages of cellular respiration in order?
1. Glycolysis 2. Krebs Cycle 3. ETC (electron transport chain)
100
What is glycolysis?
A biochemical pathway in which one six-carbon molecule of glucose is oxidized to produce two three-carbon molecules of pyruvic acid
100
What is the Krebs Cycle?
A biological pathway in which a single pyruvate molecule is made into carbon dioxide
100
What is the ETC?
Is a sequence of electron carrier molecules that shuttle electrons down a series of reactions that release energy; used to make ATP.
100
There are two types of Cellular Respiration, what are they?
Aerobic and Anaerobic Respiration
200
What is Cellular Respiration?
The process in which cells make energy in the form of ATP by breaking down organic compounds
200
What is the Net Yield of ATP in Glycolysis?
2 ATP (a total of 4 ATP were made but 2 were used initially in this biological pathway)
200
What is the Net Yield of ATP in the Krebs Cycle?
2 ATP
200

What is the Net Yield of ATP in the ETC?

~30 ATP

200
Compare and Contrast Aerobic and Anaerobic Respiration
anaerobic respiration Both processes include glycolysis. In aerobic respiration oxygen (O2) is needed and in anaerobic respiration no oxygen needed. Aerobic produces 36 ATP; Anaerobic produces 2 ATP.
300

Total amount of ATP produced in Cellular Respiration

Roughly 32 ATP molecules

300
Where does Glycolysis occur in the cell?
In the cytosol or cytoplasm
300
Where does the Krebs cycle take place?
in the mitochondria specifically the mitochondrial matrix.
300
Where does the ETC take place?
Inner membrane of the mitochondria
300
What are the two types of Fermentation?
Lactic acid and alcohol fermentation
400
What is the formula for Cellular Respiration
C6H12O2 + 6O2 ------> 6CO2 + 6H20 + Energy (ATP)
400
What are the products of Glycolysis?
2 ATP, 2 NADH, and 2 pyruvates
400

What are the products of the Krebs Cycle(per cycle)?

 3 NADH, 1 FADH2, 1 ATP (GTP), 2CO2

 

400
Another name for the ETC?
Oxidative phosphorylation
400
What organisms undergo fermentation?
Bacteria, yeasts, and muscle cells
500
How are Photosynthesis and Cellular Respiration dependent on each other?
The reactants found and in cellular respiration are the products made in photosynthesis.
500

Explain what occurs during glycolysis 

glucose a six molecule carbon becomes 

2 pyruvates molecules 3 molecule carbon 

 makes 4 total ATP in the process and makes 2 NADH 

500

In the mitochondrial matrix, what happens to the leftover carbon molecule? 

stays in the cycle

500
What enzyme causes the phosphorylation of ATP
ATP Synthase
500
Compare and contrast lactic acid fermentation and alcohol fermentation
Plant cells and unicellular organisms undergo alcoholic fermentation while our muscle undergo lactic acid fermentation when we work out and don't have enough oxygen in our bodies. However both types of fermentation don't require oxygen, use pyruvic acid, and turn NADH to NAD+.
