    ~Carbon dioxide and energy
}

Which of the following causes muscle cramps after an intense workout? {
    ~Ethanol
    ~Carbon dioxide
    =Lactic acid
    ~Pyruvate
}

The fermentation is defined as\: {
    ~The breakdown of glucose in the presence of oxygen.
    =The conversion of glucose to ethanol and carbon dioxide in the absence of oxygen.
    ~The process of ATP generation in the mitochondria.
    ~The synthesis of glucose in plant cells.
}

Which of the following is a characteristic of aerobic respiration? {
    ~It occurs in the absence of oxygen
    ~It produces ethanol as a byproduct
    =It occurs in the mitochondria
    ~None of the above
}

Which process yields more ATP? {
    =Aerobic respiration
    ~Anaerobic respiration
    ~Both produce the same amount
    ~None of the above
}

Anaerobic respiration in yeast is commonly known as\: {
    ~Photosynthesis
    =Fermentation
    ~Glycolysis
    ~Electron transport chain
}

    ~36 ATP
    =2 ATP
    ~38 ATP
    ~4 ATP
}

//True or False

Respiration is not breathing. {T}

Cellular respiration is the reverse of photosynthesis. {T}

A large supply of oxygen is necessary for anaerobic respiration. {F}

Anaerobic respiration and fermentation mean the same thing. {F}

A small amount of energy is produced during aerobic respiration. {F}

Ethanol is toxic and unsuitable for human consumption. {T}

Aerobic respiration requires oxygen to produce energy. {T}

Yeast undergoes aerobic respiration to produce ethanol. {F}

Aerobic respiration produces more energy than anaerobic respiration. {T}

//Match the following

Match the following items from Column A with their correct corresponding options from Column B\:
{
=Aerobic respiration -> Requires oxygen
=Anaerobic respiration -> Occurs in the cytoplasm
=Fermentation -> Produces ethanol in yeast
=Mitochondria -> Site of aerobic respiration
=Lactic acid -> Produced in muscle cells under low oxygen conditions
}
