Respiration is the breakdown of sugar to produce what molecule? | ATP |
What 2 molecules make ATP? | ADP & Pi |
What type of respiration requires oxygen? | aerobic respiration |
What type of respiration does not require oxygen? | fermentation |
In which part of the cell does fermentation occur? | cytoplasm |
In which part of the cell does most of aerobic respiration occur? | mitochondria |
What is the net gain of ATP during aerobic respiration? | 38 ATP |
What is the net gain of ATP during fermentation? | 2 ATP |
What type of sugar is broken down during respiration? | glucose |
What molecule is glucose initially broken down into? | pyruvate |
Apart from ATP, what 2 other molecules are produced during aerobic respiration? | water & carbon dioxide |
Apart from ATP, what other molecule is produced during fermentation in plants? | ethanol |
Apart from ATP, what other molecule is produced during fermentation in animals? | lactic acid |
Why is fermentation lethal to plant cells? | ethanol is produced which builds up and becomes toxic to cells |
