Respiration
Nat5 Unit 1 Section 8 DHS
| Question | Answer |
|---|---|
| The high energy molecule formed during respiration. | ATP |
| When oxygen is present; this is the total number of high energy molecules produced by the second chemical reaction of respiration. | 36 |
| The number of high energy molecules produced by the first stage of respiration. | 2 |
| When oxygen is present; this is the total number of high energy molecules produced by the breakdown of a glucose molecule by respiration. | 38 |
| When oxygen is not present; this is the total number of high energy molecules produced by the breakdown of a glucose molecule by respiration. | 2 |
| These substances are required to increase the rate of the chemical reactions which take place during respiration. | Enzymes |
| This liquid is produced by plants and yeast during respiration without oxygen. | Alcohol/ Ethanol |
| This type of respiration needs oxygen. | Aerobic respiration |
| When oxygen is present; the second stage of respiration takes place in these cell structures | Mitochondria |
| This is the name of the first stage of respiration. | Glycolysis |
| This type of respiration occurs when oxygen is not present. | Anaerobic respiration |
| This piece of equipment is used to measure the rate at which an organism is carrying out respiration. | Respirometer |
| This substance joins to a phosphate molecule to form the high energy molecule made during respiration. | ADP |
| This substance is broken down during the first stage of respiration. | Glucose |
| In plants and yeast; this is an alternative term used to describe respiration without oxygen. | Fermentation |
| The first stage of respiration takes place in this cell structure. | Cytoplasm |
| In the first stage of respiration; this substance is made by the breakdown of glucose . | Pyruvate/ Pyruvic Acid |
| In animals; this acid is formed in the second stage of respiration when oxygen is not present. | Lactic acid |
| This gas is formed during respiration. | Carbon Dioxide |
| This gas is combined with pyruvate during the second stage of aerobic respiration. | Oxygen |
| These substances are formed by the breakdown of ATP. | ADP + Pi |
