Final answer:
Healthy human brain cells and heterotrophic plant cells have similar energy metabolism processes, including the use of ATP and glucose as sources of energy.
Step-by-step explanation:
The energy metabolism of healthy human brain cells (neurons) and heterotrophic plant cells, such as root cells of the rice plant, are similar in several ways.
First, both types of cells use ATP as their main energy currency. ATP is produced through processes like glycolysis, which occurs in both brain cells and plant cells.
Second, both brain cells and plant cells rely on glucose as a major energy source. Glucose is broken down through glycolysis to generate ATP for cellular metabolism.
