Answer :
Answer:
C. oxygen
Explanation:
Oxygen is needed to help the process of turning glucose into ATP. The initial step releases just two molecules of ATP for each glucose.
The molecules must be present in order for energy production to occur in the mitochondria of an animal cell - c. Oxygen.
In order for energy production to occur in the mitochondria, the process known as cellular respiration takes place.
- In the mitochondria Kreb's cycle, the second phase of cellular respiration takes place.
- Cellular respiration can be either aerobic in presence of oxygen or anaerobic in absence of oxygen.
- In animals, aerobic cellular respiration takes place that requires oxygen and glucose in order to produce energy and carbon dioxide.
Thus, The molecules must be present in order for energy production to occur in the mitochondria of an animal cell - c. Oxygen.
