Glycolysis |
Breakdown of glucose for energy |
Definition |
|
|
Equations of glycolysis |
Glucose + 2 NAD + 2 ATP + 2Pi yields 2 pyruvic acid + 2NADH +2ATP |
Start with glucose |
|
|
Which can be used to generate additional ATP? |
Pyruvic acid and NADH |
Glycolysjs |
|
|
Which process is aerobic in glycolysis? |
Pyruvic acid + acetyl coA |
|
|
|
Which process is anaerobic in glycolysis? |
Conversion to lactic acid |
|
|
|
What is lactic acid pathway? |
Anaerobic respiration |
|
|
|
What is anaerobic respiration? |
Lactic acid pathway |
|
|
|
What is lactic acid pathway (anaerobic respiration) process? |
Conversion of glucose to lactic acid by reduction of pyruvate (as opposed to oxygen) |
|
|
|
Lactic acid pathway ( anaerobic respiration ) occurred in which condiction? |
Lacking of oxygen |
|
|
|
What is the end product of lactic acid pathway (anaerobic reapiration) ? What does it do? |
End products are lactic acid with a net gain of 2 ATP per glucose |
|
|
|
Where are lactic acids most relevant? |
Red blood cell and skeletal muscle cells |
|
|
|
What is ischemia? |
Lack of blood flow |
|
|
|
What is angina? |
Chest pain |
|
|
|
What is infarct? |
Heart attack |
|
|
|
What is vasodilators (nitroglycerin, ACE inhibitors, NO)? |
These drugs reduce ischemia |
|
|
|
Why do cells not store glucose? |
Because due to osmotic and permeability |
|
|
|
What is the storage form of glucose? |
Glycogen |
|
|
|
What is the two primary sources of glycogen? |
Liver and skeletal muscle |
|
|
|
The formation of glycogen from glucose is called? What are the two primary sources? |
Glycogenesis. Skeletal muscle and liver |
|
|
|
What is glycogenolysis? |
The breakdown of glycogen to glucose-6-phosphate, which enters the glycolytic cycle |
|
|
|
The cori cycle- |
Gluconeogenesis |
|
|
|
Glycogenolysis produces what? |
Glucose-6-phosphate |
|
|
|
Can G-6-P transported out of the cell? |
No |
|
|
|
Describe the Cori Cycle |
Cori cycle-gluconeogenesis. Glycogenolysis produces Glucose-6-phosphate. G-6-P cannot be transported out of the cell. In liver, G-6-P can be converted to glucose and released to the blood, via the enzyme glucose- 6-phosphatase. This reaction occurs in the liver because cells in the liver make enzyme. Lactic acid, amino acids, and glycerol can also be converted to G-6-P and glucose by the liver. |
|
|
|
What can also be converted into G-6-P and glucose by the liver? |
Lactic acid, amino acid, and glycerol |
