Cellular Respiration Flashcards
During the citric acid cycle oxaloacetate combines with the acetyl group of acetyl co-enzyme A.
What is the name of the product formed?
Citrate
During the citric acid cycle, how many intermediate molecules are formed when citrate is converted back into oxaloacetate?
3
The following items refer to some metabolic pathways that occur in cells.
- Glycolysis
- Electron transport chain
- Carbon fixation
- Citric acid cycle
Which are the pathways involved in aerobic respiration?
1,2 and 4
Glycolysis, the citric acid cycle and the electron transport chain are all processes that occur during aerobic respiration.
Where does each take place
Glycosis = cytoplasm
Citric acid cycle = matrix of the mitochondria
Electron transport chain = inner membrane of the mitochondria
The electron transport chain is the third stage of aerobic respiration.
What is pumped across the membrane?
Hydrogen ions
The following refer to different substances present in aerobic respiration.
- Acetyl Coenzyme A
- Oxaloacetate
- Pyruvate
- ATP synthase
Which of these contain substances which are associated with the citric acid cycle?
1 and 2
Glycolysis is a pathway that takes place during aerobic respiration.
Where within the cell does glycolysis take place?
Cytoplasm
During glycolysis, energy is required for what process?
Phosphorylation of glucose and intermediates
The electron transport chain takes place during aerobic respiration.
Where within the cell does the electron transport chain take place?
Inner membrane of the mitochondria
Dehydrogenase enzyme removes hydrogen ions and electrons and passes them to the co-enzyme NAD to form NADH.
In which stage(s) of aerobic respiration does this process take place?
Glycolysis and the citric acid cycle
Aerobic respiration comprises different stages that all take place in different locations within the cell.
Which stage of aerobic respiration occurs within the matrix of the mitochondria?
Citric acid cycle
What substance is glucose broken down into during glycolysis?
Pryruvate
Glycolysis, Citric acid cycle and the Electron transport chain are three processes which occur in cells.
Which metabolic process involves all 3 pathways?
Aerobic respiration
The citric acid cycle takes place during aerobic respiration.
Where within the cell does the citric acid take place?
Matrix of the mitochondria
Below are statements that refer to some metabolic pathways that occur in cells.
1.Glycolysis
2. Electron transport chain
3. Carbon fixation
4. Citric acid cycle
Which pathway is NOT involved in aerobic respiration?
3
Aerobic respiration comprises different stages that all take place in different locations within the cell.
Which stage of aerobic respiration occurs within the inner membrane of the mitochondria?
Electron transport chain
During glycolysis more ATP is produced than is used.
What term describes the production of this energy?
Energy pay off phase
The electron transport chain is the third stage of aerobic respiration.
What releases energy as they are passed along the chain?
Hydrogen ions
The following refer to different processes that occur in aerobic respiration.
- Glucose converted to pyruvate
- Oxaloacetate combining with acetyl co A to form citrate
- Formation of carbon dioxide.
- Production of ATP
Which contain processes that take place in the citric acid cycle?
2, 3 and 4
Dehydrogenase is an enzyme that is involved in aerobic respiration. The function of dehydrogenase enzyme is . . .
Removing hydrogen ions and electrons
What is the name of the pathway that produces pyruvate from the breakdown of glucose?
Glycosis
Dehydrogenase enzymes remove hydrogen ions and electrons and passes them onto a co-enzyme.
Which term correctly identifies the name of the co-enzyme?
NAD
The breakdown of glucose and intermediates during glycolysis requires the use of ATP.
What term describes the use of this energy?
Energy Investment
Which substance must be present for the citric acid cycle to take place?
Oxygen
