Question 35

Mitochondria generate energy for the cell.

Mitochondria are often referred to as the powerhouses of the cell because their primary function is to generate energy in the form of adenosine triphosphate (ATP) through the process of cellular respiration.

A) Control the cell

This option is incorrect because while mitochondria play a role in energy production, they do not control cellular activities. Control of the cell is primarily managed by the nucleus, which regulates gene expression and cellular functions.

B) Generate energy

This option is correct as mitochondria are essential for producing energy through oxidative phosphorylation. They convert nutrients into ATP, which is vital for cellular processes and functions.

C) Synthesize proteins

This option is incorrect because protein synthesis occurs primarily in the ribosomes, not in the mitochondria. Mitochondria do contain some genetic material and can produce a few proteins, but their main role is not protein synthesis.

D) Package waste for removal

This option is also incorrect. Waste packaging and removal are functions typically associated with the cell's lysosomes and the endoplasmic reticulum. Mitochondria do not serve this purpose.

Conclusion

Mitochondria are crucial for energy production, making option B the definitive correct answer. Other options misrepresent the functions of the mitochondria, focusing on roles that are primarily attributed to other cellular components, such as the nucleus and ribosomes.
