Card: 3 / 40 |
|
|
Glycolysis |
Card: 4 / 40 |
|
|
True or False: Anaerobic respiration produces more ATP than aerobic respiration. |
Card: 5 / 40 |
|
|
False. Anaerobic respiration produces 2 ATP, while aerobic respiration produces 38 ATP. |

|
Catabolic |
Card: 16 / 40 |
|
|
Which plant part does not respire? |
Card: 17 / 40 |
|
|
None; all plant parts respire. |
Card: 18 / 40 |
|
|
True or False: Respiration and photosynthesis are identical processes occurring in plants. |
Card: 19 / 40 |
|
|
False. They are opposing processes; the products of one are the reactants of the other. |

In aerobic respiration, what are the end products? |
Card: 21 / 40 |
|
|
CO₂ and H₂O |
Card: 22 / 40 |
|
|
What is the role of enzymes in respiration? |
Card: 23 / 40 |
|
|
They catalyze each step of the respiration process. |
Card: 24 / 40 |
|
|
Riddle: I am the gas taken in during respiration and released during photosynthesis. What am I? |
Card: 25 / 40 |
|
|
Oxygen (O₂) |
Card: 26 / 40 |
|
|
What happens to the water level in the delivery tube of a flask containing germinating seeds during respiration? |
Card: 27 / 40 |
|
|
The water level rises, indicating oxygen use. |
Card: 28 / 40 |
|
|
Fill in the blanks: Anaerobic respiration produces ______ and CO₂. |
Card: 29 / 40 |
|
|
Ethanol |
Card: 30 / 40 |
|
|
What is the main difference between respiration and burning (combustion)? |
Card: 31 / 40 |
|
|
Respiration occurs in multiple steps and is enzyme-catalyzed, while burning occurs in a single step and releases all energy as heat. |
Card: 32 / 40 |
|
|
In which part of the plant does the Krebs cycle take place? |
Card: 33 / 40 |
|
|
Mitochondria |
Card: 34 / 40 |
|
|
True or False: Anaerobic respiration can sustain plant parts for long durations. |
Card: 35 / 40 |
|
|
False. Anaerobic respiration cannot sustain plant parts for long and leads to their death after a few days. |
Card: 36 / 40 |
|
|
Riddle: I am a process that occurs in the dark and produces gas that turns limewater milky. What am I? |
