Answer:
D. a very fast run
Explanation:
Fermentation :
The second step of anaerobic respiration is fermentation. It involve the fermentation of pyruvate into lactic acid or alcohol depending upon the organism in which it is taking place. There is no ATP produced, however carbon dioxide is released in this step.
Anaerobic respiration in plants:
Anaerobic respiration in plants produced ethanol which if accumulate then cause the harmful effect in plants. It is also occur in some microorganisms such as yeast.
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂
Anaerobic respiration in animals:
Anaerobic respiration in animals pyruvate converted into lactic acid and it is not as harmful as ethanol in plant if accumulate. It is produced during exercise because oxygen is not supplied to muscles. It can produce the cramps which can be cured with massage.
C₆H₁₂O₆ → 2C₃H₆O₃
There is approximately 1.62g of KF depending on the rounding used
Answer:
3. is an endothermic process.
Explanation:
Generally, reactions can be classified into two. Depending on whether they absorb heat -energy or release energy.
Endothermic Reactions are those reactions in which the reaction absorb heat form the surroundings.
Exothermic reactions are those reactions that release heat to the surroundings.
This means the correct option is;
3. is an endothermic process.
