Bio chapter 7 part 3
Oxalocetic acid Citric acid
As acetate enters the Krebs cycle, it is combined with the 4 carbon compound called blank to produce the 6 carbon compound called?
Acetate
As pyruvic acid enters the mitochondria, it will be converted into what 2 carbon compound?
2 ATP
At the end of the Krebs cycle the molecule of glucose has been completely oxidized. How many ATP have been produced per molecule of glucose during the Krebs cycle?
A. The cytoplasm and mitochondria B. Anaerobic and aerobic respiration C. Glycolysis and Krebs cycle
Bridge reaction between?
If the cell relied only on glycolysis for ATP production, the cell would quickly run out of NAD+ to accept the hydrogen electrons. Without NAD+, the cell can't keep the glycolysis going and ATP production would stop.
Disadvantage of glycolysis?
2
During the bridge reactions how many NADH are produced per pyruvic acid?
Oxygen is essential for getting rid of low energy electrons and hydrogen ions.
During the cellular respiration, specifically the etc, what is the ultimate purpose of oxygen?
1 ATP
How many ATP are produced per one turn of the Krebs cycle?
1 FADH2
How many FADH2 are produced in one turn of the Krebs cycle?
3 NADH
How many NADH are produced in one turn of the Krebs cycle?
10 ATP
If 10 molecules of acetate were available for the Krebs cycle, how many ATP would be produced at the completion of the Krebs cycle?
Released as heat.
Not all of the energy contained in glucose is put into ATP begat is the rest of the energy released as?
Undergo aerobic respiration
Pyruvic acid is produced at the end of glycolysis. What will happen to the pyruvic acud in the presence of oxygen?
Pathways of fermentation
Pyruvic acid is produced at the end of glycolysis. What will happened to the pyruvic acid in the absence of oxygen?
Cristae
The inner membrane has many folds and loops called?
Glycolysis
The process in which one molecule of glucose is oxidized to produce two molecules of pyruvic acid
Hydrogen atoms ATP Carbon dioxide
The purpose of the Krebs cycle is to churn out what three molecules?
Used to pump hydrogen proteins across the membrane from the matrix to the inner membrane space.
Throughout the ETC, the movement of electrons generates energy. What is this energy used for in regards to the hydrogen ions?
A. Enter the mitochondria for the Krebs cycle B. May stay in the cytoplasm for fermentation.
What are the two possibilities for the path that pyruvic acid will take after the first stage of respiration ends with the production of pyruvic acid?
1. Doesn't require oxygen 2. The process is so fast that 1000's of ATP are produced in just a few milliseconds. 2 ATP per molecule of glucose.
What are two advantages of glycolysis?
If there is or isn't oxygen present. ( aerobic, anaerobic)
What determines which path the pyruvic acid will take?
Used in the next step to generate huge amount of ATP
What happens to the NADH and FADH2 that are produced?
Released when you exhale
What happens to the carbon dioxide that had been produced?
The cristae
What increases the surface area for the reactions of the respiration process?
To carry high energy electrons to the etc
What is the purpose of NAD+ and FAD in cellular respiration?
2 CO2 1 ATP 3 NADH 1 FADH2
What is the total amount of CO2, ATP, NADH and FADH2 that is produced during one turn of the Krebs cycle?
4 CO2
What is the total number number of carbon dioxide molecules that are produced per molecule of glucose
2 FADH2
What is the total number of FADH2 produced per molecule of glucose?
6 NADH
What is the total number of NADH produced per molecule of glucose?
Matrix
What name is given to the center potion of the mitochondria; it contains enzymes, ribosomes, and mitochondrial DNA.
CO2
What waste product is produced during the Krebs cycle
Cell membrane
Where does aerobic respiration occur in a prokaryotic cell?
Cristae membrane
Where in the mitochondria does the ETC occur?
Matrix of mitochondria
Where in the mitochondria does the Krebs cycle take place?
