Question

Anaerobic respiration normally occurs?

• A. Grass
• B. Cactus
• C. Coconut
• D. Baker's

Answer 1

The correct option is A Grass

When no oxygen is present, plants can temporarily use anaerobic respiration to create energy. It is not as efficient, since the glucose molecule does not break down completely, but rather changes into ethyl alcohol and carbon dioxide and creates only two molecules of ATP, or adenosine triphosphate. ATP is a means of storing energy in the form of sugars at the cellular level. Plants cannot keep up the anaerobic respiration process for long, only a few days at most. High temperatures increase the respiration process so more carbohydrates are used. When temperatures become very high for an extended period, the turfgrass plant may use so much of its carbohydrate supply that too little remains for growth and the plant goes dormant.

So the correct option is 'grass'.
