In the combined processes of glycolysis and cellular respiration, what is consumed and what is produced?
- Carbon dioxide is consumed, and water is produced.
- Water is consumed, and ATP is produced.
- Glucose is consumed, and carbon dioxide is produced.
- ATP is consumed, and oxygen is produced.
Glucose is consumed, and carbon dioxide is produced.
2
Which of the following describes the process of glycolysis?
- It represents the first stage in the chemical oxidation of glucose by a cell.
- Glycolysis occurs in the mitochondria.
- Glycolysis produces 30 ATP from each molecule of glucose.
- It requires ATP and NADH.
It represents the first stage in the chemical oxidation of glucose by a cell.
3
Most of the energy that the cell obtains from the oxidation of glucose is stored in NADH and FADH2.
- True
- False
True
4
The oxidation of compounds by the citric acid cycle requires molecular oxygen.
- True
- False
False
5
In the absence of oxygen, what is the net gain of ATP for each glucose molecule that enters glycolysis?
- none, because in the absence of oxygen, no ATP can be made
- none, because all of the available energy remains in either lactate or ethanol
- four ATP
- two ATP
two ATP
